EVALUATION OF AUTOMATIC BRAKING FOR COLLISION AVOIDANCE

The aim of this paper is to evaluate the influence of a vehicle with automatic braking system in a platoon on a highway. Automatic braking system is one function of collision avoidance systems that belong to ACC. Using the Monte Carlo method, the effect of longitudinal collision avoidance of an ACC vehicle included in a group of manual vehicles is simulated. The simplicity of the motion and collision models means that the lateral and vertical movements were excluded. If an ACC vehicle is in a platoon of 10 vehicles, and if it has automatic braking system and one-twelfth faster reaction time than a human driver, probability of collision in a platoon would be reduced to 85 to 90 percent of a result of a platoon without ACC. Also, total probability of fatality would be reduced to 30 to 80 percent of the result of a platoon without ACC. If ACC has only 15 percent better braking ability than other manual vehicles in the same platoon, it causes 10 percent more collisions in the platoon total. Especially the collsions on the vehicle behind ACC increases to 1.5 times in comparison to the case without ACC. The results suggest that ACC and collision avoidance systems would be safety equipment in case of "ACC assists only human reaction performance." However, if ACC outperforms human ability in ordinal traffic, ACC would be isolated and an unsafe element.
