A low carbon fuel standard (LCFS) seeks to reduce greenhouse gas emissions by capping an industry’s carbon emissions per unit of output. California has launched an LCFS for automotive fuels; others have called for a national LCFS. We show that this policy causes production of high-carbon...

Hydrogen has been proposed as a low polluting alternative transportation fuel that could help improve urban air quality. This paper examines the potential impact of introducing a hydrogen-based transportation system on urban ambient ozone concentrations. This paper considers two scenarios, where...

In articles about China in both technical journals and the popular press one often finds an implicit assumption that Chinese consumers are on a direct path that will lead to car ownership sometime in the near-to-mid-term future. The purpose of this paper was to determine if there is a...

This report provides a summary of the results of the various studies completed in the Partnered Pavement Research Program (PPRC) during the period 2000–2004. In addition, preliminary findings of investigations, initiated but not yet implemented during this period, are included. The...

The Merced County Association of Governments (MCAG) was chosen by the Federal Highway Administration, U.S. Environmental Protection Agency, and the California Department of Transportation to pilot a new program, Partnership for Integrated Planning (PIP), which aimed to: streamline planning and...

This paper examines past experience in controlling emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) from coal-fired electric power plants. In particular, we focus on US and worldwide experience with two major environmental control technologies: flue gas desulphurisation (FGD) systems...

The Low Carbon Fuel Standard (LCFS) can play a major role in reducing greenhouse gas emissions and stimulating improvements in transportation fuel technologies so that California can meet its climate policy goals. In Part 1 of this study we evaluated the technical feasibility of achieving a 10...

Cities around the world are trying out a multitude of transportation policy and investment alternatives with the aim of reducing car-induced externalities. However, without a solid understanding of how people make their transportation and residential location choices, it is hard to tell which of...

In recent years, transportation planners have devoted more attention to the goal of increasing the non-motorized trips of children and adults. Non-motorized trips are considered important as a mean of reducing motorized trips as well increasing physical activity. Indeed, lack of physical...

Using data collected from 164 French employees of a transportation institute and 1904 residents of the U.S. San Francisco Bay Area, we operationalize a segmentation of mobility patterns based on objective, subjective, and desired amounts of mobility by various modes and overall. We define a...
