Car-following Safety Algorithms Based on Adaptive Cruise Control Strategies

Driving dynamic behaviour has been becoming increasingly complex in urban traffic, it is very difficulty to realistically measure the driver´s car-following safety behaviour because some vehicles have been equipped with the ACC (adaptive cruise control) system. In order to understand the acceleration and deceleration performance of ACC system, the comprehensive analysis of vehicle-to-vehicle safety interactions is very essential to devise some control laws for preventing rear-end collisions in the car-following situations. This paper presents the deceleration and acceleration algorithms for describing driver´s car-following safety behaviour based on adaptive cruise control strategics, the main objectives of our research are to investigate driver´s car-following safety behaviour by considering the influence of ACC, and then to develop an integrated car-following safety simulation for evaluating congested urban traffic at the microscopic level.
