英文摘要： By considering the influence of adaptive cruise control strategies upon the vehicle operation under various traffic situations,we determined the distribution of safe driving zone as well asdangerous areas during the driver's car-following process in urban traffic,and some relative experiment tests and simulation validations for vehicle-to-vehicle safety interactions has been carried out in our research. The emphasis on this project is placed on the development of a driver's safety approaching behavioural model by considering the variability of following vehicle's speed to the leading vehicle's one and the relative distances among vehicles. Furthermore, we have carried out simulation and analysis of driver's deceleration and acceleration behaviour under different driving situations after identified the key safety-related parameters. Finally the developed model has been validated by using detailed vehicle trajectory data that was collected in naturalistic driving environment. The results show that the safety-based approaching behavioural model could be used to analyze driver's car-following behaviour for driving support and to reveal the essence of traffic flow characteristics at the microscopic level.
