Cooperative Adaptive Cruise Control

Traffic congestion is growing at a faster rate than can be alleviated solely by additional road construction. Various Intelligent Transportation Systems technologies aim to increase and improve transportation via non-traditional means. Cooperative Adaptive Cruise Control (CACC) is one such technology, intended to increase traffic throughput by safely permitting shorter following distances between vehicles. Both vehicle-to-vehicle and vehicle-to-infrastructure communications help such endeavors at the micro- and macro-levels of traffic management. This report identifies the various ways in which the CACC concept could be realized and the human-factors-related implementation issues. Several research areas are suggested to address these human-factors issues.
