4th International Symposium on Transportation Network Reliability

July 22-23, 2010

University of Minnesota

The aim of the International Symposium on Transportation Network Reliability (INSTR) is to bring together researchers and professionals interested in transportation network reliability, to discuss both recent research and future directions in this increasingly important field of research. The scope of the symposium includes all aspects of analysis and design to improve network reliability, including:


This event will be held on campus at the University of Minnesota. More details will be available as the date approaches.

This conference is being sponsored by CTS at the University of Minnesota.

Ian Parry and policies to reduce climate change emissions from vehicles

In the “papers I wish I had written” department, there’s:

Parry, I. 2007. “Are the Costs of Reducing Greenhouse Gases from Passenger Vehicles Negative?” Journal of Urban Economics. 62: (2): 273-293.

You can find it here.

From the abstract:

Energy models suggest that the costs of reducing carbon emissions from transportation are high relative to those for other sectors. This paper discusses why taxes (or equivalent permit systems) to reduce passenger vehicle emissions produce large net benefits, rather than costs, when account is taken of (a) their impact on reducing other highway externalities besides carbon and (b) interactions with the broader fiscal system. Both of these considerations also strengthen the case for a tax-based approach over fuel economy regulation, while fiscal considerations strengthen the case for taxes over grandfathered emissions permits. The paper also comments on the practical relevance of automobile fuel taxes, or their policy equivalents, to broader legislation intended to mitigate climate change.
