Abstract: The use of new telecommunication technologies represents an important factor to improve road safety. In such context, simulations have been carried out in order to estimate the effectiveness of the Advanced Driver Assistance Systems (ADAS) on board of heavy vehicles. Specifically a general framework for safety evaluation of Adaptive Cruise Control (ACC) and Cooperative ACC (CACC) in rear-end collisions is described. Considering probabilistic distributions for reaction time, tyre performance, braking deceleration and vehicle time gaps, various Monte Carlo simulations were carried out for different values of traffic speeds and pavement conditions, so as to calculate the probability of multi-vehicle collision.

Keywords: heavy vehicles; vehicle safety; ADAS; advanced driver assistance systems; multi-vehicle collisions; road safety; reaction time; tyre performance; braking deceleration; vehicle time gaps; Monte Carlo simulation; adaptive cruise control; rear-end collisions; traffic speed; road conditions.
