| Abstract: | From the views of objective safety of road traffic system and subjective safety of road users, this paper analyzed the safety of vehicles in free flow and non-free flow by using traffic conflict technique, driving speed prediction method and simulation analysis on dynamics performance of the vehicle (spatial sight-distance model, artificial neural network model). Then the indexes of car-following risk, lane-changing risk and high-speed risk were proposed respectively. Finally, evaluation methods and criteria for road traffic system operating safety were set up. |
