Mode shift is at the core of sustainable transport in all world cities; yet we know comparatively little about it. The Crossmodal project has sought to shed light onto this knowledge gap. Crossmodal studies cross-modal demand effects in urban passenger transport, that is, the demand effect on one transport mode of an alteration to another mode., e.g. how petrol prices affect bus demand. Such knowledge is crucial for policy makers who want to change the transport system towards a more sustainable modal mix. Methodologically, the project has focused on cross-elasticities of demand, diversion factors, mode choice and suppressed/induced demand. These are central concepts in economics, modelling/engineering and mathematics. A general finding relates to the fact that there are strong limits as to how much the quality of one mode can affect the demand for another mode - e.g. the impact on car use of reducing public transport fares. That said, we find travel time elements to have the strongest impact across transport modes. If the aim is to reduce car use, it is more effective to improve public transport travel times than to reduce their fares.The project has maintained focus on stakeholders throughout, with an active user group which has followed the project. The project has been an international cooperation between TØI (Norway) and Leeds ITS (UK). An expert panel has overseen the scientific quality of the project.
