摘要
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 driver＇s driving behavior in diverging area of freeway interchange, a detailed site investigation to many freeway interchange diverging areas was carried out, and a large number of research data was obtained by using NC200 detector and video detection. By analysis of extracted speeds and video observation, three afflux processes to the deceleration lane were summed up, and the characteristics that the drivers begun to slow down before entering the diverging area and the drivers＇ desired speed is greater than the ramp limit speed when reaching the end of the deceleration lane （ triangle side） were also summarized. There is some difference between the findings and the original assumptions. It is significant to guide the design of length of deceleration lane and transition curve parameters.
