Car-Following Model Based on Driving Behavior and Research on the Stability of the Model

Established car-following model based on driving behavior, and look forward to be applied in traffic simulation, traffic safety and intelligent transport control. Researched on different driving behavior and established car-following model correspondingly. By analyzing the model, determined the reasonable value range of the parameters and simulated various car-following processes. The car-following model established based on driving behavior can simulate actual driving behavior precisely. The value range of parameters of car-following models established according to different driving behavior is different. Different driving behavior requires different safe headway. When the values of the parameter exceed the rational range, the corresponding car-following behavior is unsafely. We drew the conclusion by simulation of car-following motorcade: taking safe time headway as definition of safe headway is superior to using safe space headway; vehicles in fluctuant motorcade must keep longer safe headway than in stable motorcade; the accelerating or decelerating performance of vehicles has small influence to safe headway; vehicles have better accelerating performance must keep longer safe headway, and vehicle has worse decelerating performance requires longer safe headway.
