文摘The desired speed will help the drivers control their driver behavior that could directly influences the traffic safety.This paper presents a basic definition of a driver's desired speed,and analyzes the effects of road geometer parameter,driver behavior and vehicle performance on the desired speed.By setting the familiar horizontal curve as the research environment,the generating process of the desired speed was described.Then,combined with the desired trajectory,the effect of driver's identification of vehicle dynamic on the desired speed was highlighted.Based on the vehicle dynamic theory,a desired speed model that consisted of the desired trajectory,the driver's experience and vehicle parameter was established and numerically analyzed.
