National transport models recent developments and prospects

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.
