Evaluation of the effect of cooperative infrastructure-to-vehicle systems on driver behavior

摘要

In-vehicle technologies and co-operative services have potential to ease congestion prob lems and improve traffic safety. This paper investigates the impact of infrastructure-to-vehicle co-operative systems, case of CO-OPerative SystEms for Intelligent Road Safety (COOPERS), on driver behavior. Thirty-five test drivers drove an instrumented vehicle, twice, with and without the system. Data related to driving behavior, physiological mea surements, and user acceptance was collected. A macro-level approach was used to evalu ate the potential impact of such systems on driver behavior and traffic safety. The results in terms of speeds, following gaps, and physiological measurements indicate a positive impact. Furthermore, drivers' opinions show that the system is in general acceptable and useful.
