Air pollution at many types of intersections and other roadside “hot spots†is not accurately characterized by state-of-the-practice models. In this study, data were collected on traffic flows, second-by-second CO and NO2 ambient concentrations in Shanghai, China. The sampled data were...

From: A Short History of Carsharing in the 90's. Journal of World Transport Policy & Practice 5 (3), 18 - 40 The vast majority of automobile trips in U.S. metropolitan regions are drive-alone car trips. In 1990, approximately 90 percent of work trips and 58 percent of nonwork trips in the United...

Climate change has fully entered the public consciousness, but what to do and how fast to do it remains intensely controversial. Questions about how to mold transportation policy to help achieve climate goals were the focus of the Asilomar conference hosted by the UC Davis Institute of...

Greenhouse gas emissions in developing countries are increasing most rapidly in the transportation sector. Even people with low incomes are meeting their need for mobility, and projected income growth over the next two decades suggests that many more will acquire personal modes of...

Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS) (January 18, 2007), calls for a reduction of at least 10 percent in the carbon intensity of California’s transportation fuels by 2020. It instructed the Secretary of the California Environmental Protection Agency to coordinate...

Transport activity, a key component of economic development and human welfare, is increasing around the world as economies grow. For most policymakers, the most pressing problems associated with this increasing transport activity are traffic fatalities and injuries, congestion, air pollution and...

To reduce transportation emissions and energy consumption, policymakers typically employ one of two approaches – changing technology or changing behavior. These strategies include demand management tools, such as ridesharing and vehicle control technologies – cleaner fuels and fuel...

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...

A survey of vehicle owners was conducted in New York State and California to explore the potential target market for methanol in the household sector. Data were colleted on revealed and reported premium gasoline purchase behavior and willingness to pay for cleaner fuels and more power. We found...
