考虑车辆价值的倒计时信号交叉口 驾驶员驾驶行为建模

为了发现车辆价值是否对驾驶员在倒计时信号交叉口的驾驶行为产生影响， 以激进型驾驶行为、普通型驾驶行为和保守型驾驶行为为典型的驾驶行为，运用交叉口 录像获取数据方法，采集了车辆经过典型倒计时信号交叉口时的车辆价值、车速、倒计时 剩余时间、所在车道等具体数据，并对3 种驾驶行为进行了判定，建立了分时段的倒计时 信号交叉口驾驶行为Logistic 模型.结果表明，在红灯倒计时显示的3~0 s 时间段内，与保 守型驾驶行为相比，激进型驾驶行为与车辆价值、车速、所在车道有关系，普通型驾驶行 为仅与车辆价值、车速有关系；在绿灯倒计时显示时间为3~0 s 与n ~3 s 的时间段内，激进 型驾驶行为与普通型驾驶行为与车辆价值、车速有关系.结果说明，驾驶员所驾驶的车辆 价值对驾驶员在倒计时信号交叉口的驾驶行为产生影响.

Modeling of Driving Behaviors at Countdown Signalized Intersections Considering the Value of Car

In order to find out whether the value of car impacts on the driver's driving behavior at countdown signalized intersections, to aggressive driving behavior, common driving behavior and conservative driving behavior as typical driving behaviors, the use of video and data collection method, the value of vehicle, the speed, the countdown time remaining, the located lane and other specific data are obtained, three kinds of driving behavior are determined, and then that the Logistic models of driving behaviors are established for countdown signalized intersections. The results show that in the countdown period of 3s to 0s, compared with conservative driving behavior, aggressive driving behavior has a relationship with vehicle value, speed and located lane, and common driving behavior just has a relationship with vehicle value and speed. In the countdown periods of 3s to 0s and n s to 3s, aggressive and common driving behaviors have a relationship with vehicle value and speed. This indicates the value of car has influence on driving behaviors at countdown signalized intersections.
