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...

Emission inventory models are a key input to regional air quality plans, called State Implementation Plans (SIPs) in the US. These plans frequently include emissions caps, or “budgets,†to which transportation system emissions must be compared. When emissions models and vehicle...

Telecommuting centers have been in existence for more than a decade in countries outside the United States. More recently, in the U.S. the potential for these telecenters to relieve urban congestion, to contribute to air quality improvement, and to encourage local economic growth has been...

Both as a business response to internal business problems, and as a transportation demand management (TDM) strategy, telecommuting is gaining acceptance in the United States and elsewhere. Yet there is no consensus on what actually does and does not constitute telecommuting. This paper first...

Heavy duty engines are substantial contributors to NOX and PM emissions inventories in urban areas, and stringent emissions standards have been adopted as a consequence. CARB has passed very strict emissions standards for heavy duty engines beginning in 2007. Meeting these standards, especially...

Truck manufacturers and vehicle component manufacturer are exploring using fuel cell auxiliary units (APUs) in lieu of main engine idling. While fuel cell powertrains continue to face significant technical and economic barriers, the truck auxiliary power application may offer a viable near-term...

The objectives of this study were (1) to assess the responses of the auto ind ustry and consumers to changes in the exhaust emission and fuel economy standards that have occurred in the United States and California in the past thirty years (1975-2003), (2) to relate qualitatively these responses...
