Neighborhood electric vehicles (NEVs) are small, very efficient EVs that are designed to be used for urban trips at relatively low speeds. They provide the potential for greatly reduced air pollution, energy use, petroleum imports, greenhouse gas emissions, and roadspace. Because they are very...

With the passage of the Global Warming Solutions Act of 2006 (AB32), California has begun an ambitious journey to reduce in-state GHG emissions to 1990 levels by 2020. Under the direction of executive order S-20-06, a mandated Market Advisory Committee (MAC) charged with studying market-based...

This article reviews major events and trends in metropolitan transportation planning and policy during the 1990s in three divergent Pacific Rim jurisdictions: New Zealand, Chile, and California. Major metropolitan areas in each country have seen rising motorization, increasing congestion, and...

Over the past five years, analysts and policymakers have become increasingly interested in the “full social cost†of motor vehicle use. Not surprisingly, there is little agreement about how to estimate the social cost or why, with the result that estimates and interpretations can...

The computer program CAL3QHCR has been recommended by the U.S. Environmental Protection Agency (EPA) for modeling carbon monoxide (CO) concentrations at intersections. EPA's guidelines for modeling CO concentration ([CO]) levels at roadway intersections outline a procedure to identify...

This paper addresses methodological issues in the estimation of travel-related impacts of telecommuting, based on findings from eight telecommuting pilot programs. Several of the studies address energy use (both travel-related and home-based) and one provides information on emissions of air...

Hydrogen has been proposed as a low-polluting alternative transportation fuel. This dissertation analyzes the lifecycle air quality impacts of hydrogen and gasoline use in light duty vehicles, including impacts from fuel production, delivery, and vehicle use. The analysis is conducted for...

Several electric vehicle (EV) cost studies have been prepared in recent years. These studies employ a broad range of assumptions and methodologies, and the disparate results that they report are a testament to the uncertainties surrounding the potential manufacturing costs of EVs. This report...
