为研究高速公路互通立交分流区驾驶员的驾驶行为,对国内多条高速公路互通立交分流区进行了调研,利用视频检测和NC200检测器获得了大量的调研数据。通过速度提取和视频观测分析,总结了驾驶员驶入互通立交减速车道的3种驾驶过程,以及驾驶员在进入分流区前已经开始减速和车辆到达减速车道终点(三角端位置)时驾驶员的期望车速大于匝道限速的特点。相关研究结论与原有假定不同。对指导减速车道长度、缓和曲线段等的设计具有重要意义。
In order to study the driving behavior of pilots in expressway interchange, a lot of survey data have been obtained by video detection and NC200 detector. Through the speed extraction and video observation and analysis, the author summarizes three driving processes in which the driver enters the decelerating lane of the interchange and the driver’s decelerations before entering the diverting zone and the arrival of the driver at the decelerating lane end point (the triangular end position) Expected speed is greater than the ramp speed characteristics. The relevant research conclusion is different from the original assumption. It is of great significance to guide the design of deceleration lane length and curve section.
