Abstract: Curve sections are commonly considered as accident-prone sections on highways,which is a hot issue in the field of road safety and traffic control simulation.On the basis of field theory in psychology,this study attempts to construct equipotential lines of driver psychology field in term of the concept of time-distance,and proposes a novel framework of a car-following model on curve sections of highways.An optimal strategy based on improved headway is proposed to enhance the anti-interference capacity of car-following model on curve sections.In this study,systemic modeling and digital simulation are conducted on CarSim and Matlab.The digital simulation results show that moderate speed,acceleration and headway on curve sections can be obtained using the proposed car-following model.
