摘要
实测了3支无信号T型交叉口速度和车头时距数据,经过统计分析后发现交叉口附近内外侧车道车辆的平均速度差别很小、主路上进口车速85%位车速约为65.0km/h、进口处的速度方差和离散度不会随交叉口距离的变化而明显变化,初步标定了左转车辆车头时距分布模型.
The paper analyzed the characteristics of speed and headway of vehicles at unsignalized T- intersections with 4 lanes on major road and 2 lanes on minor road.Filed data was collected at 8 intersections. It was found the difference of average speed of vehicle between traveling on outside lane and traveling on inside lane was not clear.The 85 percent of speed of vehicles at major approach waved near 65.0 km/h.It was also interested to find the variance and disperse of vehicle speed did not change with the dis...
