Real-time information for more efficient freight transport

How can real-time information in intermodal freight transport mitigate impacts from disruptions – and thereby achieve a high efficiency for the transport operations? This is the subject of Per Wide’s doctoral thesis, where operational disruptions have been in focus. Those have minor impacts on the transport but they occur often, for example traffic problems in terms of congestions.

What challenges do you focus on in your research?

There are challenges in reducing extra costs that occur in intermodal freight transport operations due to disruptions. At the same time, there is challenges around to what extent the use of information from information systems, that can offer real-time information to manage these disruptions, influence these extra costs. High costs and inflexibility in intermodal transport operations provide issues to compete with road-based freight transports.

How do you address the problem?

To mitigate the impacts from disruptions and, in that way, lower extra costs on the intermodal freight transport operations my research has investigated real-time information around how a disruption is detected, and how its impacts are predicted, that then leads to an action to change the original plan with the aim to manage a disruption. Additionally, to increase the understanding around the challenges about information and its impacts on the management of disruptions, the efficiency impacts on intermodal freight transport operations are compared when different real-time information is given.

What are the main findings of your research?

The results show how real-time information creates new opportunities but also demands on the management of disruptions. For example, real-time information can support a management of disruption before impacts have occurred and mitigate impacts on transport operations. In that way real-time information can avoid reactive management of disruptions, when impacts on the transport operations have already occurred and the management relates to higher costs. The thesis also shows how coordination between actors influences the availability of real-time information when a disruption occurs. Moreover, the impacts on operational efficiency measures from disruptions are investigated for various scenarios for real-time information.
 
Real-time information has been found to take an active or a passive role for the management of disruptions in intermodal freight transport. The active role for real-time information needs understanding around real-time information and how actors involved in the transport chains coordinate their operations.

What do you hope your research will lead to?

I hope my research will lead to increased understanding about the weight real-time information has for management of disruptions, that can lead to less impacts from disruptions and high efficiency in intermodal freight transport. Hopefully the research can lead to a process view on how disruptions are managed with support of real-time information. Transport managers and planners can create an understanding for how their management of disruptions can be adjusted to avoid management after impacts from disruptions have occurred, that is linked to high extra costs compared to the planned transport. Hopefully can a high efficiency in intermodal freight transport create improved conditions for a shift from road-based transport.
