Federal, state, and local governments spend over a hundred billion dollars per year to build and maintain roads and provide a variety of services, such as highway patrol, for motor-vehicle users (see report #7 in the author's social-cost series). To pay for these infrastructure and service...

Over the last several decades, hydrogen fuel cell vehicles (FCVs) have recently emerged as a zero tailpipe-emission alternative to the battery electric vehicle (EV). FCVs have some important differences from gasoline internal combustion engine vehicles, and they have only been on the road for a...

The use of ultracapacitors in plug-in hybrid vehicles (PHEVs) with high energy density lithium-ion and zinc-air batteries is studied. Simulations were performed for various driving cycles with the PHEVs operating in the charge depleting and charge sustaining modes. The effects of the load...

Smart parking management technologies may provide a cost-effective tool to address near-term parking constraints at transit stations. Smart parking management systems have been implemented in numerous European, British, and Japanese cities to more efficiently use parking capacity at transit...

The problem of hydrogen station location is often studied through understanding refueling behavior or reviewing the experience of gasoline stations. Driven by the notion "where you drive more is where you more likely need refueling", this paper develops a new approach where station siting is...

A geographic information system (GIS) framework is appealing to model supply-side decisions because spatial relationships commonly used by developers to evaluate building sites, such as the proximity to transportation facilities, existing land uses, political boundaries, and environmentally...

Various alternative fuels and vehicles have been proposed to address transportation related environmental and energy issues such as air pollution, climate change and energy security. Hydrogen fuel cell vehicles (FCVs) are widely seen as an attractive long term option, having zero tailpipe...

This paper concerns the economic and environmental challenges confronting California and the potential role for clean energy systems and hydrogen as an energy carrier in helping to address these challenges. Hydrogen in particular has recently gained great attention as part of a set of solutions...

Route 5 near the Florin Road overcrossing (PM 17.2/17.9) in Sacramento County is one of the eight quiet pavement test sections where traffic noise measurements are being conducted by the Caltrans Division of Environmental Analysis Team. This section is a rubberized asphalt concrete open graded...

Suburban sprawl has been widely criticized for its contribution to auto dependence. Numerous studies have found that suburban residents drive more and walk less than residents in traditional neighborhoods. Accordingly, smart growth programs have been advocated as a means to reduce auto travel....
