摘要：
In terms of car-following critical condition, the characteristics of freeway rear-end mechanism was analyzed. The four kinds of situation of freeway rear-end collision were studied and the quantified index of rear-end collision risk was inferred according to the rear-end collision kinetic theory. Considering the random effect of driver's reaction time, brake deceleration, the Monte Carlo method was used to calculate the value of rear-end collision risk. The scope of threshold value was then obtained by fuzzy clustering method. The results can provide the theoretical foundation for early warning of freeway driving safety.
