This paper develops an empirical model of the relationship between road traffic accidents and traffic flows. The analysis focuses on the accident externality, which is determined mainly by the difference between the marginal and average risks. The model is estimated using a new data-set which...

This timely book deals with the problem of pricing passenger and freight transportation within Europe. The contributors argue that current legislation affecting pricing and regulation is increasingly less successful in dealing with market failures and externalities such as congestion, air...

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...

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...

This report organizes and discusses empirical estimates of the effects of fuel prices and fuel emission standards on consumer and firm behaviour. I touch only briefly on model-free estimates. The focus is on results based on explicit models, taken mostly from the industrial organization...

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 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...
