Modeling of Driver Controlling at Car-Following Based on Preview Follower Theory

The driver controlling model of car-following based on preview follower theory is advanced by analyzing the relation of direction controlling and velocity controlling on the following car and regarding the whole car-following course as preview-follow to the velocity of the leading car for n times. The model could describe the car-following behaviors more truly due to the safety decision index is the time headway, not the headway distance. And how to establish the comprehensive evaluation object function is analyzed mainly. The model could imitate the controlling course of car-following in different operation conditions, show the differences among different drivers, so it could adapt for the change of traffic environment by setting the felicitous parameters for each driver. It is with portability.
