EVALUATION OF THE ENVIRONMENTAL EFFECTS OF INTELLIGENT CRUISE CONTROL (ICC) VEHICLES

Intelligent Cruise Control (ICC) vehicles are already commercially available in Japan and should be ready for the North American market by next year. Though ICC controllers are local and string stable however, it is not clear how these vehicles perform environmentally. In this paper we show that ICC vehicles can accurately track a lead vehicle and attenuate position errors generated by the lead vehicle during smooth transients. Furthermore, the smooth response of ICC vehicles designed for human factor considerations filters out traffic disturbances caused by rapid acceleration transients. Such ICC vehicle properties have beneficial air pollution and fuel consumption effects that are significant when the manual vehicles perform aggressive rapid acceleration maneuvers. These results are obtained using Pipes human driver vehicle following model which models the slinky type effects observed in today's manual driving. In this paper the response of the Pipes model is compared with that of human drivers. It is observed that Pipes model gives a smooth approximation of human driver response during the presence of transients. We have demonstrated using simulations that the fuel consumption and pollution levels present in manual traffic can be reduced during rapid acceleration transients by 28.5% and 1.5%-60.6% respectively due to the presence of 10% semi- automated vehicles
