Proceedings of the National Hydrogen Association Annual Hydrogen Conference (NHA 2006), March 12 - 16, 2006 The development of a hydrogen refueling infrastructure is a challenging proposition, especially in the transition where the number of hydrogen vehicles is low. These challenges include the...

Proton Exchange Membrane fuel cell (PEMFC) technology for use in fuel cell vehicles and other applications has been intensively developed in recent decades. Besides the fuel cell stack, air and fuel control and thermal and water management are major challenges in the development of the fuel cell...

Excessive speed is considered to be a major contributing factor to motor vehicle crashes and is thus an important focus of highway enforcement efforts. Automated speed enforcement programs have been widely applied outside the U.S. to address speeding-related safety problems. This literature...

State-of-the-art methods for the safe and efficient design of bicycle facilities are based on difficult to collect data and potentially dubious assumptions regarding cyclist behavior. Simulation models could offer a way forward, but existing bicycling models in the academic literature have not...

Carsharing provides members access to a fleet of autos for short-term use throughout the day, reducing the need for one or more personal vehicles. Over ten years ago, carsharing operators began to appear in North America. Since 1994, a total of 40 programs have been deployed—28 are...

The United States is experiencing dramatic growth in commercial vehicle truck travel on our nation's roadway system as well as critical shortages in truck parking. California ranks first in the nation's overall (private and public) commercial vehicle parking shortage. Recent estimates of the...

Diesel vehicle sales in the European Union have increased from 23% of all light duty vehicles sold in 1994 to 41% in 2002. This rapid increase in market penetration is due to four related factors: a voluntary agreement by European automobile manufacturers in 1998 to reduce CO2 emissions from new...

The University of California Information Center for the Environment (ICE) and the California Department of Transportation (Caltrans) are developing a GIS-based analytical framework to improve the effectiveness of biological mitigation throughout California. Goals include incorporating the best...

Presented at the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 The first step, in any program of self-improvement, is admitting you have a problem. My friends and colleagues, I would like to talk to you today about two big problems....
