National and European transport models become increasingly important. The broadening of national transport policy from strategic infrastructure investments to infrastructure management strengthens the need for advanced and more policy sensitive tools of analysis. The increase of interregional and international mobility requires forecasting tools that go beyond the urban or regional level. The competition for national infrastructure investments among regions and for Trans-European investments among nations has to be resolved by decisions and decision support systems at the appropriate spatial level. Environmental impacts transcend regional and national boundaries and transport policies affecting these environmental impacts involve all spatial levels. This volume presents the state of the art and prospects of a sample of the most advanced national and European transport models within a comparative framework.

The transport system is central to our lives as our means to travel, but also has major impact on our environment. This has become most salient in recent years through its contribution to climate change. However, this perspective has only had a minor impact on the conventional economic analysis and modelling of transport investments, creating a dissonance between the traditional objectives of investment and the strategic need to reduce carbon emissions to Net Zero by 2050. Travel Behaviour Reconsidered in an Era of Decarbonisation argues that our transport networks are mature, and the objective should be to improve operational efficiency. Over the past half century, large public expenditures in roads and railways were justified by an analytic approach to the benefits of investment, primarily the value of the time saved through faster travel, to both business and non-business users of the networks. However, average travel time has not changed over this period. People have taken the benefit of faster travel as better access to people, places, activities and services, with the ensuing enhanced opportunities and choices. This book argues that the basis of orthodox transport economic analysis has been misconceived and a fresh perspective on economic analysis is now needed.
