Abstract

In order to improve road safety, the probability distribution of vehicle collision speeds and acceleration peaks were investigated in this paper. First, based on statistical data from the National Highway Traffic Safety Administration in the U.S., the probability density function of vehicle collision speeds was worked out. Next, a finite element model of trolley impact system was built. Through analyzing data generated by this simulation model, a regression model was developed to reveal the association between collision speed and acceleration peak. Then, the expectation and variance of acceleration peak were calculated. The results show that collision speeds follow a normal distribution and there is the biggest possibility of collision accidents happening at middle and low speeds. The numerical characteristics of acceleration peak are useful for optimizing of automobile safety system under the condition of random impact.
