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...

In this paper, we discuss the greenhouse gas emission reduction potential from international shipping. Drawing from the International Maritime Organization's most recent assessment of maritime greenhouse gas emissions and other sources, we investigate the current level of emissions from...

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...

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...

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...
