Abstract:Electric Vehicles are the only type of cars that get “cleaner” over time, as electrical power generation begins to convert slowly over time to lower-polluting energy sources. Hybrids, plug-in hybrids, and battery electrics are conservatively estimated to reach a five percent national car park by 2030. Drastic increases in the price of gasoline resulting from oil shocks or major shifts in national energy and environmental policy, however, may push Electric Vehicles (EV) quickly beyond this small share. Should such critical changes occur, EVs will be poised to move beyond their current niche to gain wider scale acceptance and integration into transportation and energy infrastructure.
Currently a number of automobile manufacturers are considering use of higher cost composite materials and other strategies to reduce the weight and improve the mobility range and performance of EVs.
At the behest of consumers and freight and transit fleet operators, automobile manufacturers have to date designed, manufactured, and marketed EVs primarily as an urban mobility solution.
Crash avoidance applications, designed to reduce vehicle-vehicle crashes such as forward collision warning and blind spot detection, would likely greatly benefit unconventional vehicle categories.
Vehicle-to-Vehicle cooperative crash avoidance systems, such as one that utilizes vehicle Dedicated Short Range Communications (DSRC) technology, is a potential future solution to reduce the safety impact of differences in vehicle size and structural compatibility. The benefits of widespread deployment of DSRC for Vehicle-to-Vehicle cooperative safety may spillover into the development of Vehicle-to-Infrastructure (V2I) applications.
