Evaluating Safety Benefits of Collision Mitigation Systems (CMS) : A Challenge

This paper present a new method for the evaluation of collision mitigation safety (CMS) benefits. The authors focus on an automatic CMS that can apply a 1g braking deceleration at TTC=0.5s, during 0.5s. The authors assume three different CMS sensor detection capabilities that generate then three CMS types. A global model of the CMS is then presented, from technical specification to market penetration, with appropriate hypotheses. This model enables a discussion of safety benefits and a sensitivity analysis with respect to the main parameters, as well as of error causes and margins. Their work includes as well a sensitivity analysis with variation in the parameters used: CMS activation; deceleration capability; the proportion of drivers that brake with appropriate force, with insufficient force or do not brake at all; and modeling errors in empirical curves plotting the individual probability to be injured versus equivalent energy speed (EES). The authors conclude by estimating that the use of CMS systems could result in up to 30% reduction in fatalities from automobile collisions, particularly in rural areas.
