Regulators, policy analysts, automobile manufacturers, environmental groups, and others are debating the merits of policies regarding the development and use of battery-powered electric vehicles (BPEVs). At the crux of this debate is lifecycle cost: the annualized initial vehicle cost, plus...

The purpose of this paper is to examine the relationships between travel behavior and immigrant status. The National Household Travel Survey (NHTS) allows us to explore the relationships between travel behavior and characteristics that are usually hard to discern in surveys with smaller samples....

We report the results of a survey of the potential demand for electric vehicles (EVs) among a subset of California households. We limit our analysis to one group of potential hybrid households. These households own two or more light duty vehicles and buy new vehicles of the body styles we expect...

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...

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...
