Over the past 10 to 15 years, the growth of passenger vehicle travel volumes has decelerated in several high-income economies and, in some, growth has stopped or turned negative. Drawing from work presented to and discussions at the ITF Roundtable on long-run trends in travel demand, held in...

A brief review of long run projections of demand for road transport suggests that problems related to road network congestion and greenhouse gas emissions are likely to become more pressing than they are now. Hence we review, from a macroscopic perspective, popular policy measures to address...

The allocation of traffic between different transport modes follows transport user decisions which depend on the generalized cost of travel in the available alternatives. High Speed Rail (HSR) investment is a government decision with significant effects on the generalized cost of rail transport;...

Transport activities have adverse environmental and health impacts, of which local and regional air pollution, climate change, and noise impacts are the most important. This paper is a non-comprehensive overview of existing and potential policies to deal with these negative impacts, with a focus...

This paper discusses the role of transportation in policies to address energy security and climate change. It focuses on three elements: the impact of energy prices on transport demand, the potential contributions of the transport sector to energy policies, and the interaction between energy and...

Standard textbook analyses of road pricing tend to assume that users are homogenous, that there is no travel time risk, and to have a view of congestion as static. The simple analysis also ignores that real pricing schemes are only rough approximations to ideal systems and that the general...

The future of interurban public transport will be significantly affected by public sector decisions concerning investment in infrastructure, particularly the construction of new high-speed rail lines in medium-distance corridors where cars, buses, airplanes and conventional trains are the...

The case for including agglomeration benefits within transport appraisal rests on an assumed causality between access to economic mass and productivity. Such causality is difficult to establish empirically because estimates may be subject to sources of bias from endogeneity and confounding. They...

“Green growth” is an emerging paradigm that integrates several policy aspirations, including the durability of economic activity, reduced environmental impacts, and sustained growth in high-quality employment in such a way as to foster coherent, cross-sectoral policy design. Focusing on...

It is difficult to separate the individual effects of the recession and the 9/11 attack. Within this severe constraint, the national economic impact of 9/11 appears to have been both modest and short-lived. This is supported by the sharper decline in industrial production in 2001 than in 2002....
