This summary report incorporates into a single document the design, construction, and performance data for the I-710 Freeway Rehabilitation Project in Long Beach, California. Included are the following: summaries of the asphalt mix and structural pavement section designs; construction sequence...

Proton Exchange Membrane fuel cell (PEMFC) technology is one of the most attractive candidates for transportation applications due to its inherently high efficiency and high power density. However, the fuel cell system efficiency can suffer because of the need for forced air supply and...

Will people recharge a vehicle that does not have to be recharged? This, and the degree to which plug-in hybrid electric vehicle (PHEV) designs emphasize gasoline or electricity, are central to assessing the energy and environmental effects of PHEVs. Plug-in conversions of hybrid vehicles are...

In this paper I discuss general conceptual issues in the estimation of the impacts of CO2 emissions from soils and biomass, over time, as a result of land-use change (LUC) due to increased demand for energy crops. The effect of LUC on climate depends generally on the magnitude and timing of...

Energy consumption could be reduced if more people shared rides rather than driving alone yet carpooling represents a small proportion of all potential carpoolers. Prior research has found that many who might carpool were concerned about reduced flexibility with carpooling. If flexibility is one...

The Institute of Transportation Studies at UC Davis (ITS-Davis) is a multi-faceted, internationally recognized program with more than 60 affiliated faculty and researchers, 100 graduate students, and a $6 million annual budget. Its primary program components are research, education and outreach....

Through mechanisms of industrial globalization, modern societies are moving ever closer to capitalist ideals, emphasizing consumer choice and free competitive markets. Despite these ideals, relatively few choices currently exist for the typical personal vehicle consumer with respect to...

California led the nation by passing the first global warming legislation in the U.S. California is tasked with reducing green house gas (GHG) emissions to 1990 levels by 2020 and 80% below 1990 levels by 2050. The California Air Resources Board estimates that significant GHG reductions from...

Our collective transportation choices have far-reaching effects both locally and globally, from traffic congestion to global warming. While the concerted actions of many travelers working together could make significant inroads into solving these problems, a single traveler working alone could...
