In order to explore the mechanism of driver risk perception in car-following under emergency situations,a large-scale investigation of traffic conflict was conducted by using video drive recorder for the first time in China.Based on the rear-end conflict data recorded in real traffic environments,authors analyzed the relationship between driver braking operation and decision-making for safe and dangerous status,presented the model of driver risk perception in car-following based on Logistic regression.Results show that time headway and time to collision are important parameters for driver risk perception in car-following,and the model presented in the paper has good adequacy in city traffic by the test of goodness of fit and accuracy verification.
