低等级公路交叉口与城市道路非信号灯交叉口车辆运行速度特征比较分析
Characteristic Comparison of Vehicle Speed at Low-grade Highway Intersection and Urban Unsignalized Intersection
摘要
Abstract
Intersections are critical junctures for low-grade highway and urban road network and at the same time they are black spots. It is of great significance to obtain the knowledge about vehicle speed characteristics in different positions so as to take traffic management measures and improve transportation facilities. This study used vehicle test to collect vehicle speeds in three kinds of distances respectively———far from, less far from and near——— the centers of urban unsignalized intersections and low-grade highway intersections. After comparison and analysis about their characteristics, distribution functions of vehicle speed in different distances to intersec-tion centers were established. It then obtained the pattern of vehicle speed variation at low-grade highway inter-sections or urban unsignalized intersections, which provides some reference for traffic management and design of transportation facilities.关键词
