This summarizes the event that Marine technology and Maritime studies hosted as part of the EU Horizon 2020 project AutoBARGE, which took place at Chalmers last week. For four days, representatives from academia and industry gathered from all over Europe to jointly pave the way for autonomous ship transport for inland waterways.</b></p>​<span style="background-color:initial">On 14 – 17 November, the divisions of Marine Technology and Maritime Sciences hosted an event within the framework of the EU Horizon 2020 project AutoBARGE, a European training and research network aiming to pave the way for autonomous ship transport for inland waterways. More specifically, the project is about both building highly qualified competence for autonomous shipping and further developing models for autonomous ships to be able to &quot;take over&quot; the role of the crew on board, as well as to satisfy socio-technical, logistical, economic and regulatory conditions for a successful and safe implementation of autonomous ships.<br /><br /></span><div>The event lasted for four days and consisted, among other things, of a two-day seminar held by leading researchers in the field from the Department of Mechanics and Maritime Sciences at Chalmers and from RISE.</div> <h2 class="chalmersElement-H2"><span>For knowledge exchange and relationship building</span></h2> <div><span style="background-color:initial">On site to take part in the event were the project's early-stage researchers and PhD students as well as representatives from industry and the EU Horizon Commission. And for a fair share of the participants, the event did not only entail knowledge exchange and education, but also a chance to see each other IRL for the first time.</span></div> <div><br /></div> <div>“The event went very well. It was the first time that a majority of the early-stage researchers, supervisors and industry beneficiaries got to meet face-to-face to build the nucleus of the interdisciplinary work and cooperation that should emerge from the consortium,” says Scott MacKinnon, professor at Maritime studies, who spoke on &quot;Human factors of maritime automation&quot; at the event.<br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/autobarge%20studenter%20750x340.jpg" alt="" style="margin:5px;width:680px;height:312px" /><br /><br /><span style="background-color:initial">“All</span><span style="background-color:initial"> the early-stage researchers involved in the AutoBARGE project got both technical and &quot;soft skills” training during the event. I believe they also started to understand the full scope of the project, which promotes the exchange of ideas and project cooperation among different research subjects within the autonomous inland shipping, such as ship systems, navigation systems, economics and law, and human factors,” says Wengang Mao, professor of ship mechanics, who together with Jonas Ringsberg, professor in Marine Structures at Marine Technology, gave a presentation themed &quot;Ship resistance and energy consumption&quot; at the event.</span><br /></div> <div>And Jonas Ringsberg especially wants to highlight the importance of the relationship-building values that come with the event.<br /><br /></div> <div>“The fourteen early-stage researchers had time on their own to discuss common research areas and get to know each other on a social and private level. We could see that they established valuable and friendly relationships, which is important and promising for their future research collaborations and personal development, says Jonas Ringsberg. <br /><br /></div> <div>During the event, a number of research areas were discussed through lectures by several researchers from the Department of Mechanics and Maritime sciences, including Monica Lundh, lecturer at Maritime studies, who lectured on &quot;Handling thick and rich data”, Henrik Ringsberg, instructor in technical and maritime management, who gave a presentation on &quot;Maritime analytic framework&quot; and Mikael Lind, adjunct professor at Maritime studies, who lectured on &quot;Port collaborative decision making&quot;.<br /></div> <h2 class="chalmersElement-H2">A European affair</h2> <div>The AutoBARGE project's long-term goal of developing an autonomous shipping transport for inland waterways is a concern for large parts of Europe. More than 37,000 kilometers of waterways connect hundreds of cities and industrial regions on the European continent and 13 countries in the EU share an interconnected waterway network. The AutoBARGE project unites European industry and academia with partners from seven universities, two high tech companies and one institute. And among the representatives from the project’s European Commission, the event seems to be considered a success.<br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/autobarge%20sal%20750x340.jpg" alt="" style="margin:5px;width:675px;height:310px" /><br /><br />“The project startup was given very positive reviews from the Project Manage of the EU Horizon Commission as well as from the early-stage researchers in attendance.<a href="https://marie-sklodowska-curie-actions.ec.europa.eu/"> The Marie Skłodowska-Curie Actions​</a> are unlike traditional research consortia where formal work plans and cooperative tasks are well defined and integrated. In this program, much self-organisation is required, and it was clear that this event sparked this process,” explains Scott MacKinnon.<br /><br /></div> <div>With the first event in place, the future looks bright for AutoBARGE, not least for the project's early-stage researchers who now are able to bring their collaborations to the next level. <br /><br /></div> <div>“The upcoming period will look exciting for them, as they will actively seek cooperation outside their host institutes and plan their secondment for research exchange and cooperation. We are also looking forward to welcoming at least three early-stage researchers from other institutes to exploit our current research results contributing to actual benefits of autonomous inland shipping,” says Wengang Mao. <br /><br /></div> <div>Text: Lovisa Håkansson</div>Thu, 24 Nov 2022 00:00:00 +0100https://www.chalmers.se/en/departments/m2/news/Pages/Full-house-at-the-inauguration-of-new-compressor-test-facility.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/Full-house-at-the-inauguration-of-new-compressor-test-facility.aspxFull house at the inauguration of new compressor test facility<p><b>​“It’s challenging and exciting to go from the application to what we have here in front of us today. You don't just throw together a facility of this magnitude while you're working on a PhD thesis,” says Isak Jonsson, researcher at the Division of Fluid Dynamics and design master mind of the new compressor facility that is now expected to take Chalmers' hydrogen research for aviation to the next level.</b></p>​<span style="background-color:initial">The inauguration of the new compressor test facility took place at the end of October at Chalmers Laboratory of Fluids and Thermal Sciences. On the guest list were about 30 people, primarily from GKN Aerospace who attended on site to learn about the rig's construction and applications for the aviation industry – as well as to get a closer look at the rig IRL. The compressor rig has been developed over the course of three years and has been made possible through funding from the EU project ENABLEH2, whose long-term aim is to enable hydrogen-powered aviation as a way to approach the EU's climate goal of a CO2 reduction in aviation by 75% from 2000 to 2050.</span><div><br /></div> <span style="background-color:initial">Present to talk about the rig's origin, development process and technical design were Tomas Grönstedt, professor of turbomachinery, Professor Valery Chernoray, Director of Chalmers Laboratory of Fluids and Thermal Sciences and researcher Isak Jonsson. And for Isak, who’s been in charge of the technical construction of the compressor facility, the day will mark a personal milestone.  <br /><br /></span><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/kompressor%20med%20folk%20750x340.jpg" alt="" style="margin:5px 10px;width:670px;height:308px" /><br /><em>Tomas Grönstedt and Isak Jonsson shows the new compressor facility to a curious guest</em><br /><br /></span></div> <div><span style="background-color:initial"><div>“I’m delighted to inaugurate this new resource at Chalmers today. This is actually my second facility for experimental studies in gas turbines with almost all components custom built, so regardless, it’s a huge undertaking in a three-year project like ENABLEH2. The fact that we’ve had to experience covid-19 with subsequent disruptions in supply chains did not exactly make the task any easier. Now, I’m looking forward to dedicating more time to education in the new MPMOB master's program and research projects such as MINIMAL,” says Isak Jonsson.</div> <h2 class="chalmersElement-H2">Aiming for a fossil-free aviation</h2> <div>The facility weighs about 8000 kilograms, consists of thousands of components and has a vertical deign. The test rig will now enable researchers to carefully study and measure air current behavior and heat exchange in a combustion engine when fueled with hydrogen – necessary knowledge when eventually introducing hydrogen as a possible fuel for the aviation industry.</div> <div><br /></div> <div>Tomas Grönstedt is the Director of Chalmers' newly established competence center TechForH2 whose overall purpose is to develop new technology in hydrogen propulsion as a step in the transition to a fossil-free transport system. For him, the newly inaugurated compressor brings new and great possibilities for future tests in the field.​<br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/kompressorrig%20tomas%20750x340.jpg" alt="" style="margin:5px 10px;width:670px;height:308px" /><br /><em>Tomas Grönstedt talks about emissions from aviation in relation to EU climate goals</em><br /><br /><div>“The scientific community and industry have tried to increase the electrification of aviation in order to reach the climate goals set by EU. But it hasn't worked. Batteries are very good but cannot offer enough range for heavier vehicles. Which is why we thought of the idea to use hydrogen as a way to increase the range. An electric-powered airplane would be able to travel 500 kilometers at most. With hydrogen, the range could increase to 3,000 kilometers,” explains Tomas.</div> <h2 class="chalmersElement-H2">Paving the way for future collaborations</h2> <div>With the completion of the compressor facility, the wind tunnel lab now houses three test rigs, which will broaden the possibilities for research and testing in even more application areas than today. And in recent years, hydrogen research has been of particular interest in the lab.  ​<br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/kompressorrigg%20Valery%20750x340.jpg" alt="" style="margin:5px 10px;width:670px;height:308px" /><br /><em>Valery Chernoray talks about application areas for the research carried out in the lab</em><br /><br /><div>“Recently, we’ve had three projects related to hydrogen in the lab and in the last three years we’ve had a total of 31 research projects in total with application areas in, for example, wind power, the shipping industry and the aviation industry, just to name a few - all aiming to make the world more environmentally friendly,” says Valery Chernoray.</div> <div><br /></div> <div>When it was time for question time, the crowd was particularly keen to know more about the construction details of the rig as well as its functionality.  </div> <div><br /></div> <div>“The compressor is a little over 1.2 m in diameter with several hundred blades, all made by very advanced manufacturing techniques. A problem with vertical design is the risk of dropping a screw into the compressor. Even if you use safety devices, it actually happened once and then I had to pick it up with the help of a magnet,” says Isak in front of a laughing audience and continues:</div> <div><br /></div> <div>“We normally run it at approximately 2,000 revolutions per minute and we test it for 10 - 12 hours straight, which means we have to work in shifts.”<br /><br />And the new facility sure seems to have sparked an interest among the invited guests.​<br /><br />“Having the opportunity to collaborate with Chalmers in research projects like these is a crucial argument in the conversations we have with our customers in the aviation industry. When we can get access to &quot;hard core evidence&quot; from research, we may also position GKN ahead of our competitors on the world map,” says Henrik Runemalm from GKN Aerospace.<br /></div> <div><br />Text: Lovisa Håkansson</div></div></div></span></div>Mon, 07 Nov 2022 00:00:00 +0100https://www.chalmers.se/en/news/Pages/funding-from-swedish-research-council-2022.aspxhttps://www.chalmers.se/en/news/Pages/funding-from-swedish-research-council-2022.aspxPrestigious funding to researchers at Chalmers<p><b>​​In their annual call for research grants, the Swedish Research Council distributes SEK 112 million to 29 researchers at Chalmers. </b></p><div><span style="background-color:initial">Chalmers was awarded grants in all announced areas, but most in natural and engineering sciences. </span><br /></div> <div><br /></div> <div>These researchers at Chalmers receive grants – sorted by department: <h2 class="chalmersElement-H2"> Architecture and Civil Engineering </h2> <div>Jelke Dijkstra </div> <div>Karin Lundgren </div> <h2 class="chalmersElement-H2">Biology and Biological Engineering </h2> <div>Rikard Landberg <br />Clemens Wittenbecher <br />Fredrik Westerlund </div> <h2 class="chalmersElement-H2">Electrical Engineering </h2> <div>Erik Ström <br />Henk Wymeersch </div> <h2 class="chalmersElement-H2">Physics </h2> <div>Riccardo Catena <br />Tünde Fülöp <br />Fredrik Höök <br />Thomas Nilsson <br />Timur Shegai </div> <h2 class="chalmersElement-H2">Chemistry and Chemical Engineering </h2> <div>Bo Albinsson <br />Anette Larsson <br />Christian Müller <br />Magnus Skoglundh </div> <h2 class="chalmersElement-H2">Mathematical Sciences </h2> <div>Klas Modin <br />Genkai Zhang </div> <h2 class="chalmersElement-H2">Computer Science and Engineering </h2> <div><span style="background-color:initial">Fredrik Johansson​</span></div> <div><span style="background-color:initial"></span>Moa Johansson <br />Paweł W.

The main focus is on a special measurement method developed by SSPA and Chalmers - which has already paid off for the sailing teams. “We’ve taken a big step forward in our sailing this year and now we have our eyes set on the Olympics in Paris in 2024 and after that the Olympics in Los Angeles in 2028,” says Ida Svensson, Swedish national sailor in the Olympic class NACRA 17.</b></p>​<span style="background-color:initial">We found ourselves at SSPA, the now RISE-owned maritime research and ship testing facility located on the Chalmers campus. From the outside, a fairly inconspicuous brick building. But on the inside – among huge tanks, workshop halls and laboratories – marine research at highest level is taking place. <br /><br /></span><div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Arash%20200x200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px" />Here we’re met by Arash Eslamdoost, Associate Professor in applied hydrodynamics at Chalmers, and Laura Marimon Giovannetti, researcher and project manager at SSPA. Together, they’ve developed a unique method to simulate and predict with great precision how hydrofoils behave in the water under a range of different conditions. Their research is of great interest to the shipping industry, which with the use of further developed hydrofoils can benefit electric vessels also over longer distances – while at the same time making the shipping industry significantly greener. How?<br /><br /></div> <div>“As the hydrofoils, like wings, lift up the boat hull and make the boat “fly” over the water surface, the resistance is reduced by as much as 80 %. Less drag means longer range for a battery fueled ship,” Arash explains.<br /></div> <h2 class="chalmersElement-H2">Speed increase of up to 50%</h2> <div>It also means that the speed of the boat can increase significantly. A phenomenon that sailing has already discovered. In recent years, hydrofoiling technology has revolutionized the sport, where the sailors today reach much higher speeds than they used to. The research that takes place at SSPA and Chalmers is hence of great interest to the competitive sailing community. And Laura's interest in hydrofoils is far from a coincidence.<br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Laura%20200x200.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 10px" />“I’ve previously competed in both the Italian and British national sailing teams and today I’m working as a technical advisor for the Swedish Olympic Committee and coach the Swedish teams,” she says.<br /><br /></div> <div>In her role, Laura technically advises the Swedish national sailing team in four different classes. One of the teams consists of sailors Ida Svensson and Marcus Dackhammar and today they are visiting the research facility to, with Laura's help, make advanced measurements on their hydrofoils in the hope of optimizing their sailing. </div> <div><br /></div> <div>For three years, the team has competed together in the Olympic class NACRA 17, that is, a 17-foot-long catamaran equipped with foils.<br /><br /></div> <div>“I’m the helmsman and Marcus is the one pulling the ropes,” says Ida.<br /><br /></div> <div><strong>The Olympic class has been in development</strong> for the last few years and has now completely switched to using foils. And there’s no doubt that the hydrofoils make a difference:</div> <div>“Previously, we only foiled downwind, but with the new rudder system introduced after Tokyo 2020, we are now able to fly upwind also, so going up against the wind, which means an increase in speed from about 10 – 11 knots to about 15 knots. In other words, an almost 50 % speed increase,” Marcus explains. <br /></div> <h2 class="chalmersElement-H2">The quest for the right degree of stiffness</h2> <div>Above all, it’s the hydrofoil stiffness that the team is interested in measuring at SSPA's facility. Ida and Marcus buy the foils from the boat manufacturer NACRA, but in order to find the hydrofoils with the best characteristics for sailing, they need to combine testing in the lab with testing in real life. <br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Ida%20och%20MArcus%20750x340.jpg" alt="" style="margin:5px 10px;width:675px;height:310px" /><br /><br /><span style="background-color:initial">“We’r</span><span style="background-color:initial">e here to measure the stiffness of the rudders and the daggerboards, which are a big part of making the boat go faster,” Marcus explains. And Ida fills in:</span><br /></div> <div>”The faster we go, the more important it becomes to have the right equipment. NACRA is a catamaran, and if we know in which side we sail faster, then we can find out which degree of stiffness results in the fastest speed.”<br /><br /></div> <div><strong>In the center of attention</strong> for today's foil testing is a measurement method that makes it possible to study the foils' stiffness at a detailed level and see how they’re affected if, for example, the load or speed increases or when the positioning of the foil changes.</div> <div>In the lab, the foils are &quot;set in place&quot; into a device and weights are attached to increase the load. Three advanced cameras document even the smallest changes in the hydrofoil and send the data directly to a computer where Marcus, Ida and Laura can see the results in real time, both in numbers and in 3D illustration.<br /><br /></div> <div>It’s a fine balancing act. The stiffer the hydrofoil, the higher the boat “flies” and the speed increases. But if the boat flies too high, the foils start to ventilate, which in turn may result in abrupt speed loss, slamming and risk of injury. <br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/marcus%20laura%20testar%20750x340.jpg" alt="" style="margin:5px 10px;width:670px;height:308px" /><br /><br /><span style="background-color:initial">“We</span><span style="background-color:initial">’ve tested a range of foils that have had a difference of 15% in stiffness and we can see that it’s a factor that makes a difference. Then of course it’s difficult to rule out other factors, such as waves, water temperature or how we behave on the boat, that is the human factor, which also might influence the sailing,” Marcus explains.</span><br /></div> <h2 class="chalmersElement-H2">&quot;We’ve taken a big step forward&quot;</h2> <div>Marcus and Ida have already noticed that the measurement in the lab pays off in their sailing. It’s not the team's first visit to the facility:</div> <div>“We were here last spring and tested the foils we had then. Now, we’ve bought new gear that we’d like to test. During this year, we’ve taken a big step forward in our sailing and now our eyes are set on the Olympics in Paris 2024 and after that the Olympics 2028 in Los Angeles,” says Ida Svensson.<br /><br /></div> <div>Although the tests that can be carried out at SSPA may be considered somewhat unique, it’s most likely that other nations also conduct similar tests on their foils. But exactly how is shrouded in obscurity.<br /><br /></div> <div>“There’s nowhere else we can get this data from. Thanks to Laura, we can connect the research done here to reality. It’s very likely that our competitors from other countries also do tests, but no one wants to share what technology they use or what the results look like,” says Ida.<br /><br /></div> <div><strong>After Ida and Marcus have completed</strong> their tests, a longer training trip to Lanzarote awaits this winter, where they will also have the opportunity to compare today's measurement results with how the foils perform in the water. The competition season starts in April and then the Olympics in Paris 2024 looms.<br /><br /></div> <div>“Right now, we’re in between 12th and 18th place in the world in our class. There are 19 countries participating in the Olympics, so first we have to get a place in the selection,” Marcus explains.<br /><br /></div> <div>And if all goes as planned, Laura and her hydrofoil research will follow the team for years to come.</div> <div>“I will continue to help the Swedish sailing team until the Olympics in Paris in 2024 and hopefully also until the following Olympics in Los Angeles in 2028,” says Laura.</div> ​<br />Text: Lovisa HåkanssonThu, 03 Nov 2022 00:00:00 +0100https://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Succes-for-premiere-of-Master-Thesis-Fair-Energy.aspxhttps://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Succes-for-premiere-of-Master-Thesis-Fair-Energy.aspxSucces for premiere of Master Thesis Fair Energy<p><b>​​On October 10, 2022, a master thesis fair with a focus on energy was held at Chalmers for the first time.

Now, new research from Chalmers University of Technology reveals a relatively unknown environmental culprit. The study shows that the discharge water from ships’ exhaust gas treatment systems, so-called scrubbers, is responsible for up to nine percent of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea, which is considerably more than was previously known.

In spite of this message, we have seen a significant increase in the number of scrubber installations as it is economically beneficial for the shipowner.

The study showed that scrubber wash water accounts for up to 9 percent of the emissions of certain cancer-causing polycyclic aromatic hydrocarbons (PAHs) into the Baltic Sea. The study also revealed that ships painted with copper-based antifouling paints account for a third of the total supply of copper to the Baltic Sea. Copper in antifouling paints is already a known environmental problem as the metal cannot be degraded in the environment and therefore leads to high levels in water, sediment and soil. But exactly how much of the load of copper boat and ship traffic accounts for, has previously been unknown. Also, the cancer-causing PAHs are difficult to degrade and can spread widely in the environment before breaking down. </span></div> <div></div> <div><br /></div> <div><a href="/en/staff/Pages/erik-ytreberg.aspx">Erik Ytreberg​</a>, Associate Professor and researcher at the Division of Maritime Studies at Chalmers University of Technology, is the lead author of the scientific study: <br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Erik%20Ytreberg%20250x300.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 10px;width:200px;height:240px" /><br />“Our results show that shipping accounts for a significant proportion of hazardous substances to the Baltic Sea, above all through antifouling paints and discharge of wash water from open loop scrubbers. PAHs are highly toxic to both humans and aquatic organisms as they are, among other things, carcinogenic. Worth noting is that the study's data was collected in 2018, and at that time there were approximately 180 ships with scrubbers in the Baltic Sea. Since then, these ships have increased significantly and in 2021 there were almost 600 ships equipped with scrubbers in the Baltic Sea,” says Erik Ytreberg. <br /></div> <h2 class="chalmersElement-H2"><br />Proposal for a future ban</h2> <div>The new research results have led the Swedish Transport Agency and the Swedish Agency for Marine and Water Management <a href="https://www.havochvatten.se/download/18.2910eb4e18168d823c8ce277/1656425767638/redovisning-ru-uppdrag-att-komplettera-tidigare-redovisning-om-utslapp-av-tvattvatten-fran-skrubbrar-pa-fartyg.pdf">to propose a ban on the discharge of so-called scrubber water into the internal waters of the Baltic Sea.</a> <span style="background-color:initial">If the Swedish politicians follow the line of the researchers and the authorities, Sweden will be the first country in the Nordic region to introduce the ban.<br /><br /></span></div> <div>Today, scrubbers are installed on over 4,000 ships around the world. In the Baltic Sea area, only Germany already applies the same legislation, even though several other countries in Europe regulate scrubber discharges in their ports. The Chalmers researchers welcome the proposal but hope for even more extensive regulation in the future.</div> <div><br /></div> <div>“The proposal that Sweden should ban the discharge of wash water into Swedish inland waters is good, but at the same time it means that only 1 - 2 percent of the discharges that occur from scrubbers in the Baltic Sea today will be regulated. Sweden could also propose a ban in our territorial waters, which would mean that roughly 15-17 percent of emissions to the Baltic Sea could be regulated. But the biggest effect would obviously come from an international ban, where all the countries around the Baltic Sea agree on a joint regulation of the discharge of scrubber water,” says Erik Ytreberg.<br /></div> <div><br /></div> <div><strong>Contact:</strong></div> <div><a href="/en/staff/Pages/erik-ytreberg.aspx">Erik Ytreberg,</a> Associate Professor and researcher in Maritime Environmental Studies at the Department of Mechanics and Maritime Sciences at Chalmers University of Technology: </div> <div>erik.ytreberg@chalmers.se +46-31-7722749.</div> <div><a href="/en/staff/Pages/idamaja.aspx">Ida-Maja Hassellöv</a>, Professor and researcher in Maritime Environmental Studies at the Department of Mechanics and Maritime Sciences at Chalmers University of Technology:</div> <div>ida-maja@chalmers.se +46-31-7723139.<br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Skrubber%20modell.jpg" alt="" style="margin:5px;width:675px;height:382px" /><br /><br /></div> <div><strong>More about the study and the research</strong></div> <div><ul><li><a href="https://www.sciencedirect.com/science/article/pii/S0025326X22005860?via%3Dihub">The scientific article Metal and PAH loads from ships and boats, relative other sources, in the Baltic Sea has been published in the Marine Pollution Bulletin</a>.

In addition, the interaction with the other students has really strengthened my network, which I think will certainly be helpful when I step into the professional world,” says Yue  Chen, one of the students who attended this year's edition of the IDEA League summer school in &quot;Analysis and Modeling of Road User Behaviour” at Chalmers.</b></p>​<span style="background-color:initial">The third edition of the IDEA League summer school in &quot;Analysis and Modeling of Road User Behaviour&quot; took place in September and, just as in previous years, it was the Crash Analysis and Prevention unit at Vehicle Safety that held the baton. 23 master's program students and doctoral students from the five different partner universities - <strong>TU Delft, ETH Zurich, RWTH Aachen, Chalmers, Politecnico di Milano</strong> – got together for a week to learn more about how road users behave in traffic. Included in the list of participants were students from a range of disciplines – computer science, psychology, geoengineering and vehicle automation, just to mention a few – all of whom were welcomed by course coordinator <strong>Giulio Bianchi Piccinini</strong>, Associate Professor of human factors in road traffic safety at M2. And it wasn't just the students who, after the pandemic's distance teaching, were looking forward to finally meeting for real.<br /><br /></span><div>“This will be my third year as course coordinator, but it is the first time that we can have the summer course on campus, which feels great. And we've made sure to include a lot of social activities in between the lectures so it will hopefully be a fun experience,” says Giulio Bianchi Piccinini. <br /><br /></div> <strong> </strong><div><strong>For course participant Yue Chen, </strong>who otherwise studies spatial development and infrastructure for systems and behaviors related to transport at ETH in Zurich, it was both the course content and the social surroundings that made her apply. <br /><br /></div> <div>“To me, the summer school is a good way to meet and develop friendships with people with different educations and cultural backgrounds. And Chalmers, with its reputation as a top-ranked technical university in Sweden and Europe, also attracted me,” says Yue Chen. <br /><br /></div> <div><strong>And her classmate Priyanka Dani</strong>, Master's student in &quot;Robotic system engineering&quot; at RWTH Aachen, agrees:<br /><br /></div> <div>“My future plan is to work in the field of autonomous mobility and the summer school felt very relevant for that purpose. In addition, there was a clear advantage in being able to visit Chalmers and experience student life here,” she says.<br /></div> <h2 class="chalmersElement-H2">Experiencing a car crash – free of risk</h2> <div>In addition to lectures on road user behavior, crash prevention and quantitative and qualitative data collection methods in the field, the course also included a visit to VTI, the Swedish National Road and Transport Research Institute. Here, the students were able to get a sense of what it’s like to try to avoid a collision at high speed - completely without risk.<br /><br /></div> <div>“This year we tweaked the course program with a visit to VTI, which has some of the most advanced driving simulators in the world. Here you can get the opportunity to simulate really dramatic scenarios that would be too risky to test in reality. But you still get to feel what it would be like to drive a car and suddenly have to brake as an elk crosses the road,” explains Giulio.<br /><br /></div> <div><strong>And for the students, </strong>the field trip was much appreciated.<br /><br /></div> <div>“It was great! It was a first time for me, and I found it very cool!” says Priyanka. <br /><br /></div> <div><div>“By watching the other students try out the simulators, I was able to learn the principles of driving simulators. And we don't have simulators like these at ETH Zurich,” says Yue. </div></div> <h2 class="chalmersElement-H2">From bicycle to electric skateboards<br /><img src="/en/departments/m2/news/Documents/IDEA%20league%20brödbild.jpg" alt="IDEA league brödbild.jpg" class="chalmersPosition-FloatRight" style="margin:5px 10px;width:250px;height:333px" /></h2> <div>And during the week-long summer school, there would be more opportunities to test drive a vehicle - also smaller ones. As it was time for <strong>Marco Dozza</strong>, Professor in Active Safety and Road-user Behavior, to give his lecture on micro-mobility, the students got to test drive segways, electric scooters, hoverboards,  electric skateboards and bicycles - all equipped with sensors to collect naturalistic riding data. The purpose? To gain a better understanding of why crashes happen and thereby also be able to better integrate micro-mobility vehicles into the transport system in a safe way.<br /><br /></div> <div>“It was fun! I got to test drive almost all the micro-mobility vehicles and also learn more about them from an engineering perspective,” says Priyanka.<br /><br /></div> <div>“I tested the electric scooter and it was interesting to see the others trying to drive the different micro-mobility vehicles and then get to talk about how they experienced them,” says Yue.<br /><br /></div> <div><strong>As the week came to an end, </strong>the students were able to collect their impressions and lessons learned from the summer school.<br /><br /></div> <div>“I thoroughly enjoyed the course! It was inspiring and informative. It was well-structured, it covered a wide field and the material we got for self-study was of high quality. Furthermore, the interaction with my colleagues really boosted my network which I believe will surely be helpful once I step into the professional world,” says Priyanka.</div> ​<br />Text: Lovisa HåkanssonWed, 28 Sep 2022 00:00:00 +0200https://www.chalmers.se/en/areas-of-advance/materials/news/Pages/2022-tandem-seminar.aspxhttps://www.chalmers.se/en/areas-of-advance/materials/news/Pages/2022-tandem-seminar.aspx2022 year's Tandem Webinars<p><b>​Here you will find 2022 all Tandem Webinars.

To remedy the problem, aircrafts and engines have historically been designed targeting efficiency improvements in order to reduce carbon dioxide emissions. But now a new international research project led by Chalmers will investigate how a new concept of designing may reduce not only carbon dioxide emissions but also other emissions – NOx, contrails and water vapor - which in short term are believed to have a relatively larger impact in global warming. Being the first of its kind, the design philosophy is considered a paradigm shift that is expected to have a major impact on the aviation industry:<br /><br /></span><div>“This will allow us to include the impact of global warming during the early stages of engine development and filter-out concepts that otherwise might look attractive.  If fully absorbed by industry, this new design philosophy has the potential to be a game changer,” says Carlos Xisto, Associate Professor in Fluid Dynamics at Chalmers University of Technology and coordinator of the project.<br /><br /></div> <div><strong>The project is called MINIMAL and was started on 1 September</strong> with funding from the EU and UKRI.

One of the most important outcomes of MINIMAL will be to bridge knowledge between atmospheric science and engine design to create more climate-friendly propulsion technology for aviation, says Carlos Xisto.<br /><br /></div> <div><strong>With funding from the EU and UKRI of six million euros</strong>, the researchers will now be able to carry out advanced experiments that, together with computational and aero-thermal-mechanical climate impact studies, can test new design concepts. The aspiration is to eventually introduce the concept to the industry for further development and brought to the market as early as 2035 – 2040, thus paving the way for an air traffic compatible with the environmental goals established in the Paris Agreement.<br /><br /></div> <div>“I hope that MINIMAL is one of those projects that could influence the aviation industry in the short-medium term.

In Hungary, it was the first time that Chalmers Formula Student competed with a driverless electric car and we still came in seventh place with 24 teams competing. So, one could say that we won the rookie league, which feels great,&quot; says Linnéus Karlsson from the Chalmers team that took part in two rounds of the world's largest engineering competition for students, Formula Student, this summer. </b></p>​<span style="background-color:initial">This year marks the 20th anniversary of Chalmers' participation in Formula Student, the world's largest engineering competition for students. Ever since 2002, students from Chalmers' Formula Student course have designed and built their own Formula cars to compete against teams from technical universities from all over the world. In the 2015 round, the combustion engines were replaced by electric motors and since 2017 a new competition class was introduced as it was due time for self-driving electric cars to enter the racetrack. <br /><br /></span><div><strong>During the summer it was time for the 2022 </strong>edition of the competitions to take place. First in Austria and a couple of weeks later in Hungary. And for the first time, the Chalmers team was able to roll out a customized electric car adapted for both manual and autonomous control to the starting grid. A result that has been prompted by a multi-year and fruitful cross-department collaboration. <br /><br /><span style="background-color:initial">“The fact that we were now going to make the car autonomous required additional skills in the team. Ever since electric cars were introduced in the competition, this project has taken place in collaboration between departments and this year we were able to bring in more to work with electronics and software. Which went very well,” says Björn Pålsson, Associate Professor of Dynamics at the Department of Mechanics and Maritime Sciences and course leader of the Formula Student course.</span><br /></div> <div><h2 class="chalmersElement-H2">“You work right to the wire&quot;</h2></div> <div>This year's Chalmers team included around 30 students, mostly Master's students from Mobility Engineering, who have worked hard since September last year to get a car ready to go on time. All stages must be completed within a few months: from pre-study, design work and building of the car and finally testing.<br /><br /><span style="background-color:initial">“It’s good engineering to start from previous designs and carry over some parts, but the majority of the parts of the car are improved and redone. According to the rules, the team must be able to demonstrate &quot;significant changes to the chassis structure&quot; for the entry to qualify. If the judges notice that the car is too similar to previous entries, they’ll be disqualified,” explains Björn.</span><br /></div> <div><br /></div> <div><strong>This year, the team also needed time to</strong> develop an autonomous part that was ready to be fitted for the self-driving race in Hungary but removed for the driver-controlled races in Austria. And the process has no doubt been paved with a considerable amount of stress.<br /><br /></div> <div>“You work right to the wire. Time is short. It’s a big task in itself to build a car and typically the ambition level is too high for the vehicle concept. The only thing we have been tampering with is the amount of test time. But the team has managed to realize their concept and their idea and I think they should be very pleased with that,” says Björn.<br /><br /></div> <div><div><strong>During the competitions, the cars are scored</strong> in static events that assess the design and financial aspects of the car, and dynamic events that include: acceleration, which means that the car should cover a distance in shortest possible time starting from standstill, a so-called &quot;skid pad&quot;, which means that the car drives in a classic figure eight-shaped track, and driving on tracks of various lengths. In the driverless race, competitors use a remote control equipped with only a start button and an emergency stop. Apart from that, the car needs to be able to get around the track autonomously.<br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/formula%20student%20lag%201%20750x340.jpg" alt="" style="margin:5px 10px;width:665px;height:306px" /><br /><br /></div> <h2 class="chalmersElement-H2">​&quot;One could say that we won the rookie league&quot;</h2> <div>So how did it go?</div> <div> </div></div> <div><strong>“In Austria, we came in tenth place in total</strong>. In Hungary, it was the first year that our team competed with a driverless electric car and we still came in seventh place with 24 teams competing. So, one could say that we won the &quot;rookie league&quot;, which feels great. And it probably beats our achievements in Austria. The other teams had been competing with driverless cars for a few years and the fact that we were able to succeed this well on the first go feels great. But we’re very pleased with our achievements in both Austria and Hungary,&quot; says Linnéus Karlsson, one of the members of the Chalmers team and master student in technical physics. <br /><br /></div> <div>“And of the 24 teams in Hungary, only four teams in total managed to get their car around the ten laps of the track drive course. And we were one of those four teams. Which we consider a success,” says Jakob Gunnarsson, also part of the Chalmers team that competed in this year's edition.<br /><a href="https://www.youtube.com/watch?v=FGendxLGk9s">Here you can watch a film from the driver controlled race in Austria</a> and <a href="https://www.youtube.com/watch?v=sQ7gVgm-L28">here you can watch one from the driverless races in Hungary! <br />​</a><br /></div> <div><strong>The Chalmers team performed best</strong> of the Nordic countries, and although their achievements are considered a success, it was – just like in previous years – the Germans who dominated on the winners’ stand. In the Austrian competition, it was the German team from Stuttgart that won the gold and in the driverless races in Hungary, the German team from Karlsruhe came in first place. <br /><br /></div> <div><div>“The German teams are very competitive, and they test more and have a lighter car. Our team at Chalmers can no doubt build a &quot;state-of-the-art&quot; car, but the best German teams are better at building a lighter car. And they also have great drivers,&quot; explains Björn. </div> <h2 class="chalmersElement-H2">Sharing of knowledge and arch-rivals</h2></div> <div>And despite the fact that the presentations that the teams give to the judges are closed to competitors, the sharing of knowledge is generous between the teams during the events. Which the Chalmers team tries to make the most out of ahead of upcoming competitions.<br /><br /></div> <div>“We’re looking at all the teams, but above all the German ones, in order to find out what is state of the art in this area. Most teams are open about their designs, and you can definitely learn from each other. And we’re developing our own power electronics within the framework of the course. So, we hope the car will be lighter next year. Currently, our car weighs a bit more than 200 kilos in the manual configuration. The best German cars only weigh about 170 kilos, says Björn.<br /><br /></div> <div><strong>The German teams may be a leading</strong> country in the field, but it’s a completely different competitor that the Chalmers team and - perhaps above all - their course leader Björn are trying to beat. <br /><br /></div> <div><div>“I’ve made NTNU in Trondheim our arch-rivals, just because it’s fun to have one and because they’re Norwegian. And this year they actually performed worse than Chalmers, even though they are normally very good. So, it's great if we can beat them once in a while. When NTNU's car broke down in 2018, the commentators said that the entire Chalmers team probably would be getting a round of beer for beating NTNU” says Björn, laughing.</div> <h2 class="chalmersElement-H2">&quot;You get to do something for real&quot; </h2></div> <div>Today, a couple of weeks after the 2022 Formula Student has been concluded, the team members are confident that the lessons learnt from the experience will bring benefits, not only in the preparations for next year’s round, but perhaps even more so for future studies as well as professional career. <br /><br /></div> <div><strong>“The best thing about this course</strong> is probably that you get to work both theoretically as well as practically. I come from Engineering Physics which is primarily theoretical. Here you really get the chance to participate and do something for real,” says Formula Student member Linnéus.</div> <div><br /></div> <div>And fellow student Jakob agrees:</div> <div>“Even in industry, you will never get the chance to get as involved in all stages of the chain. But here, you really do, from start to finish.”<br /><br /></div> <div>“A Formula student team basically faces the same challenges as a real vehicle manufacturer, but on a smaller and simplified scale. But the same skills are required. In addition, they get the practical experience of building and testing cars themselves in this project. And the course is very popular among employers. One of the main skills that the students will get is to better coordinate their skills with others and see exactly how exactly their qualities will fit into the whole entity,” says course leader Björn Pålsson.<br /><br /></div> <div><strong>In just a couple of weeks, </strong>the next Formula student course starts at Chalmers and recruitment is in full swing.</div> <div>“The students may originate from all kinds of programs at Chalmers, but mainly they tend to Master’s students from mechanical, electrical or computer science. So, just send in an application and we'll follow up with an interview,” says Björn.<br /><br /><a href="https://www.chalmersformulastudent.se/">Read here for more information about Chalmers Formula Student! ​</a><br /><br />The Chalmers Formula Student Driverless team has previously competed in the autonomous cathegory in 2018 to 2021, and the Chalmers Formula Student team has been comteting in the driver controlled cathegories between 2002 – 2021, making this year the first in which the Chalmers Formula Student team entered with an autonomous car. <br /><br />Text: Lovisa Håkansson<br /><br /></div>Thu, 01 Sep 2022 00:00:00 +0200https://www.chalmers.se/en/departments/m2/news/Pages/How-VR-technology-may-optimize-maritime-safety.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/How-VR-technology-may-optimize-maritime-safety.aspxHow VR technology may optimize maritime safety<p><b>​“VR technology is an engaging tool that can be used in a naturalistic way in maritime training to increase competence and safety on board, without a risk of accident, injury or environmental challenges,” says Scott MacKinnon, professor of maritime studies at Chalmers. Now, the technical university has been examining how these technologies can be incorporated into the curriculum for master mariner students. A first step is to help build a massive database as part of an international data collection project. The purpose? To create industry specific VR technologies that may optimize safety and efficiency in shipping. </b></p>​<span style="background-color:initial">The Department of Mechanics and Maritime Studies at Chalmers University of Technology has one of Sweden's most comprehensive simulator centers for research and education in shipping. In a realistic bridge environment with projected surrounding sea area, future Master Mariners are trained to navigate ships at sea in an efficient and safe manner. But soon the school’s maritime programs are about to become even more virtual – and thus making it one of the first of its kind. Recently, the Unit for Maritime studies entered a collaboration with <a href="https://marisot.turkuamk.fi/">MarISOT, &quot;Maritime Immersive Safe Ocean&quot;​</a>, a Finnish project that uses AI and machine learning to develop VR and AR solutions for the field of shipping.<br /><br /></span><div>“By using VR technology in maritime education, students can be trained to deal with challenging scenarios that may occur at sea - for example, if the ship were to end up in heavy traffic, or if there’s an engine failure, or perhaps a cyberattack targeting the ship. Using this sort of technology, we may increase safety and ensure that this type of challenges don’t lead to accidents. In addition, it also provides a great platform to test new navigation technologies before being put to use in real traffic,” says ​Scott MacKinnon, professor of maritime studies at Chalmers.<br /></div> <h2 class="chalmersElement-H2">Unique data collection using VR and simulators </h2> <div>As part of the MarISOT collaboration, Chalmers' undergraduate master mariner students are now assisting in collecting massive amounts of data to improve machine learning algorithms and thus making the VR technologies better for teaching and research activities in the field.</div> <div>The data collection consists of so-called synthetic data retrieved from a VR simulator developed within the MarISOT project and on loan at the unit for Maritime studies. In a realistic bridge and sea environment - and wearing VR glasses - the students get to experience virtual scenarios that may occur while at sea.<br /><br /></div> <div>“The main scenario was to navigate a ship according to a given route in open seas while avoiding other ships. A fairly ordinary day at sea, in other words,” explains Reto Weber, lecturer at Maritime Sciences at Chalmers.</div> <div>The participants' reactions and actions turn into valuable data that will be used to train algorithms to develop VR and AR programs for educating maritime students in the future – and subsequently also increasing competence and safety on board. <br /><br /></div> <div>“The VR glasses were not only used to visualize a given scenario, but with the help of so-called &quot;eye-tracking&quot; we were also able to obtain data on where the participants looked, for how long, and which functions were used in the equipment - radar, telegraph, control and so on. In addition, the researchers in MarISOT aim to measure changes in pupil size for a given scenario, which may indicate whether the person in question was stressed or not,” says Reto Weber.</div> <h2 class="chalmersElement-H2">VR-based learning for future shipping </h2> <div>As part of the project, senior maritime students have been functioning as instructors, thus training more junior students to maneuver ships from the simulator bridge in the VR-based exercises. The approach has come to be known as Student Based Simulator Training (SBST) and aims to not only let VR technology permeate the pedagogy as well as the technical competence, but also give them skills in communication, leadership, problem solving, organization and creativity in an increasingly digitized and AI -based shipping.</div> <div>While VR and AR are technologies that have already been integrated in a range of industries - such as in the aviation and energy industry - this is considered one of the world's first projects of its kind in the maritime education and research area. <br /><br /></div> <div>“With huge amounts of data, we may significantly improve the machine learning algorithms and thus make the VR technology better and more mature for teaching and research in shipping,” says Scott MacKinnon.<br /><br /></div> <div>For more information: <a href="/en/staff/Pages/Scott-MacKinnon.aspx">Scott MacKinnon </a>scottm@chalmers.se +46-31-7721465 or </div> <div><a href="/en/staff/Pages/reto-weber.aspx">Reto Weber</a> reto.weber@chalmers.se +46-31-7723884</div> <div>Read more <a href="https://marisot.turkuamk.fi/">about MarISOT here</a></div> <div><br /></div> ​Text: Lovisa HåkanssonTue, 16 Aug 2022 00:00:00 +0200https://www.chalmers.se/en/departments/m2/news/Pages/Autonomous-drone-system-could-save-lives-at-sea.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/Autonomous-drone-system-could-save-lives-at-sea.aspxAutonomous drone system could save lives at sea<p><b>​In recent years, thousands of refugees and migrants have fled across the seas as a result of humanitarian crises around the world.

The quadcopter – a drone that has four engines and therefore the ability to hover – can carry loads weighing up to about two kilograms.</div> <div><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/sjösättning%20drönare%20300x350.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px" /><br /></div> <div><strong>&quot;The project is based on the simple principle</strong> that different drones have different advantages, and by allowing several different types of autonomous drones to work together, search efficiency and rescue response speed can be significantly improved, with the potential to save more lives,&quot; says <strong>Xin Zhao</strong>, post-doc in the Fluid Mechanics Division at Chalmers.</div> <div><br /></div> <div><strong>Tomas Grönstedt,</strong> Professor in the Fluid Dynamics Division, says:</div> <div><br /></div> <div>&quot;In addition, the system could – in principle – be linked to any public service or to volunteers who could provide some form of assistance.&quot;</div> <h2 class="chalmersElement-H2">Automatic battery charging and launching the next stage</h2> <div>The marine drone,<strong> Seacat</strong>, provides an internet uplink as well as a local communication link that is used to coordinate the flying drones. It also includes a launch pad for the fixed-wing drones. All airborne drones are equipped with cameras and a positioning system. All drones can move fully autonomously – the marine drone follows a predefined route with a closed loop. Fixed-wing drones are automatically assigned to search areas according to an intelligent algorithm that makes best use of the number of drones available. When a fixed-wing drone detects objects in the water, the quadcopter is sent to the scene to take pictures. The photographs can then be sent to a rescue centre on land via the marine drone. The rescue centre, for its part, can send out the quadcopter with supplies. When one of the winged drones runs out of battery, it is taken out of service and lands in the water near the Seacat drone, where it can be picked up and recharged automatically, and then sent out again.</div> <div><br /></div> <div><strong>‘&quot;So far, we have succeeded in carrying</strong> out a quadcopter landing on Seacat, and the winged drones have been built and are in the process of being assessed,&quot; says <strong>Ola Benderius</strong>, Associate Professor in the Vehicle Engineering and Autonomous Systems Division, who has also led the project.</div> <div><br /></div> <div>‘&quot;As part of a continuation of the project, we will put the system together and test it in its entirety out at sea.&quot;</div> <h3 class="chalmersElement-H3">More about the project</h3> <div>The drone system has been developed in collaboration between the Vehicle Mechanics and Autonomous Systems Division and the Fluid Dynamics Division of the Department of Mechanics and Maritime Sciences.</div> <div><br /></div> <div>The marine drone and the winged drones are designed from scratch, built and tested at Chalmers.</div> <div><br /></div> <div>The team includes Tomas Grönstedt, Xin Zhao, Isak Jonsson and Carlos Xisto from the Fluid Dynamics Division, Ola Benderius from the Vehicle Mechanics and Autonomous Systems Division of the Department of Mechanics and Maritime Sciences, Leif Eriksson from the Earth Sciences and Remote Sensing Division of the Department of Space, Earth and Environment and Christian Berger from the Software Engineering Division of the Department of Computer Science and Engineering.</div> <div><br /></div> <div>The project is being run within Chalmers’ research infrastructure Revere, with funding from the Transport Area of Advance.

And compared to other collisions, truck accidents are three times more common to end in fatalities. “If we want to achieve the Vision Zero - no more traffic deaths - we need to address the over-representation of heavy goods vehicles in fatal crashes. With this framework, we can contribute to developers and society at large by getting better safety systems on the market and thereby reduce the number of collisions and injuries in the future,” says Ron Schindler. By analyzing data from truck collisions throughout Europe, he and his colleagues have developed a framework for developing better truck safety systems. </b></p>​<span style="background-color:initial">Each year, more than 1.1 million road crashes occur in Europe. Of these, 23,000 have a fatal outcome. And despite the fact that heavy trucks are involved in only about four percent of these crashes, their share in fatal crashes is three times higher. With his dissertation<a href="https://research.chalmers.se/publication/fa257c57-5742-4d59-94e0-137f304859c1"> &quot;A holistic safety benefit assessment framework for heavy goods vehicles&quot;​</a>, Ron Schindler, PhD student in the Crash Analysis and Prevention group at the division for Vehicle Safety at Chalmers, wants to find a way to increase road safety for heavy trucks. The result is a newly developed framework designed to better evaluate safety systems introduced for truck traffic.<br /><br /></span><div><strong>“If we want to achieve the Vision Zero</strong> - no more traffic deaths - we need to address the over-representation of heavy goods vehicles in fatal crashes.

Seat belts and airbags are examples of two passive safety systems, i.e. systems that are activated when the collision has already taken place. In recent years, there has been an increasing focus on the development of active safety systems that are activated before the crash takes place, such as automatic braking systems. Before introducing new safety systems on the market, it is important that they are evaluated in an effective way, to ensure that only the best ones are used in traffic. Until now, a large part of the research in road safety has focused on passenger cars, and no effective ways of evaluating safety systems have been available. <br /></span><br /></div> <div><strong>“A lot of research has so far focused on cars</strong>, but they are completely different from heavy goods vehicles. The vehicle design itself looks completely different and, also, those who drive the different vehicles do so under very different circumstances. So, we cannot just use all the work and research that has been invested into passenger car drivers, but we needed to work with data related to heavy goods vehicles,” explains Ron. <br /><br /></div> <div>When evaluating safety systems, virtual simulations based on driver behavior models are used. However, these models are based on drivers in passenger cars and information on how truck drivers behave in critical situations has not been available. To create an effective framework, Ron and his research colleagues have therefore analyzed data from truck collisions from all over Europe.<br /><br /></div> <div>“<strong>We needed to collect data on typical crash patterns</strong> that involved heavy goods vehicles from various European crash databases. We have also collected and analyzed detailed driver behavior data from a test track experiment and developed a new methodology to create synthetic populations of drivers,” explains Ron. </div> <div>The result is a unique framework that aims to provide manufacturers and system developers with a tool to understand how well a newly designed safety system would work in real truck traffic.<br /></div> <h2 class="chalmersElement-H2">Paves the way for increased truck safety</h2> <div>In the study results, Ron and his research colleagues were able to see how the behavior of truck drivers changed in situations where so-called vulnerable road users - pedestrians and cyclists - were present. The research group could identify differences both in the trucks’ movement patterns as well as in the truck drivers gaze behavior when a vulnerable road user was nearby. The results have implications for new regulations and system evaluation strategies (such as done by Euro NCAP for example), and may not only be used when designing frameworks that evaluates safety systems, but can also inform the design of new safety systems for truck traffic in the future.<br /><br /></div> <div><strong>“If we can identify the driver's behavior </strong>change when a cyclist is present, we can suppress a warning to not &quot;disturb&quot; the driver. If a cyclist is present, but the driver behaves instead in a way that is normal for when no cyclist is present, a warning could be triggered as it is likely that the driver has not noticed the cyclist and that there is an imminent danger for a conflict or collision,” says Ron.<br /><br /></div> <div>Read more about the research project <a href="https://research.chalmers.se/publication/fa257c57-5742-4d59-94e0-137f304859c1">A Holistic Safety Benefit Assessment Framework for Heavy Goods Vehicles</a></div> <div><br /></div> <strong> </strong><div><strong>Contact info: </strong></div> <div>Ron Schindler, PhD student in the Crash Analysis and Prevention group at the division for Vehicle Safety at Chalmers at the department of Mechanics and Maritime sciences, Chalmers. </div> <div>+46-31-7721536 </div> <div>ron.schindler@chalmers.se</div> <div><br /></div> <div>Text: Lovisa Håkansson</div>Fri, 01 Jul 2022 00:00:00 +0200
