Transportation Propulsion, Fuels and Emissions
Alternative fuels will play an increasingly large role in reducing harmful pollutants created by vehicle exhaust emissions, as well as reducing dependence on imported fossil fuels. TRSC research includes life-cycle analysis of biofuels, tar sands and other non-traditional sources, hydrogen, electric and hybrid (including plug-in) vehicles, reduction of greenhouse gases and other transportation-related emissions, and establishment of low-carbon fuel standards.

Advanced Vehicles and Intelligent Transportation System (ITS)
The term Intelligent Transportation Systems (ITS) refers to the application of advanced technologies, such as electronics, communications, and information processing, to vehicles and transportation infrastructures. TSRC research involves the use of ITS for smart cars, smart parking for trucks, goods movement, and virtual weigh stations.

Policy and Planning
This area of research encompasses smart growth, alternative land use, transit, carsharing and car-free housing.

Mobility for Special Populations
By 2029, there will be some 770 million Americans over the age of 65. As the population ages it will be imperative to find new ways to meet the transportation needs of those citizens who will eventually become unable to drive. In addition, as the immigrant population grows, it is necessary to look more closely at their travel patterns to understand how best to use limited transportation resources. People with disabilities also need transit alternatives. TSRC researchers are examining non-traditional transportation modes, transit, and non-motorized travel for all these populations.
