MODELLING REAR-END COLLISIONS AND COUNTERMEASURES

This paper presents the results of an analytical study of rear end collision-warning algorithms using the REAMACS simulation. REAMACS (Rear End Accident Model And Countermeasure Simulation) is a quasi-Monte Carlo simulation that models rear end collision situations in freeway traffic and estimates the benefits of collision-avoidance systems. Vehicle speed and following distance data are obtained from a file of actual freeway data. Other parameters such as driver reaction time and braking levels are sampled from known distributions. The analysis indicates that it is possible to provide an imminent crash warning with the potential to significantly reduce the number of rear end collisions in freeway type traffic without producing an excessive number of nuisance alarms. Full effectiveness is achievable with a system range less than 100 m. Adding a following-too-close warning is effective mainly against low speed crashes and could be a serious annoyance, at least to some drivers.
