摘　　要：首先 ,将遇到黄灯时车辆所处状态细分为进退两难、减速停车、匀速通过和选择通过 4种状态 ,驾驶员根据车辆当前的位置和速度来确定其处于何种状态 .其次 ,在考虑不同的驾驶员具有不同的驾驶技术和攻击性性格的基础上 ,驾驶员根据车辆当前所处的状态做出相应的反应行为 ,这就是整个决策过程的建模思路 .通过计算机仿真以及对信号交叉口车辆的实地测量表明 :模型能够表现驾驶技术带来的判断和操作偏差 ,并能够表现出现实中存在于黄灯期车辆加速、减速、匀速和紧急刹车 4种典型行为 ,以及其中的违规现象 .从统计比对结果来看 ,仿真表现与现实是近似的 ,但还是有局部的差异 ,这种差异主要源于仿真中对行人行为的忽略 .该仿真模型可以用来表现混杂交通中驾驶员遇到黄信号灯时的反应行为 。When a driver meets with the yellow running, he is facing to four alternates-dilemma, braking, straight-through running, and option. The driver judges which situation is in according to his current speed and location; and then the instantaneous situation hints the driver to make the corresponding operation based on the driver's skill and aggressive character. This driving behavior model for the amber light is confirmed by the simulation result that the model not only represents four types of driving behaviors: accelerating, braking, straight-through running and full braking, but also represents red-running violations during an amber light, which is attributed to driving skill and aggressive character. It can be concluded from the contrast that the simulation result is rather statistically similar to the data acquired from the spot; but there is the partial difference which mainly derives from the neglect of the pedestrians and bicycles behaviors in the simulation. Therefore, this model, as a part of vehicle model, can offer a theory base to the algorithm of driving behavior during an amber light under the mixed and disordered traffic micro-simulation.
