摘要
城市支路设计缺乏统一标准,不合理的支路系统将影响主次干路与支路间的协调作用,使整个城市道路网络运营效率降低。文章从驾驶员心理感受、操作的方便性、速度调整3个方面研究了支路应该满足的最小长度;并针对城市支路存在的一些问题提出了相应的改善措施,从而为支路的规划和设计提供参考。
Our country usually ignores the importance of road branch in planning and design of city road in the network. There exists some problem in network of branch system such as incompletion,low density,irrationality of layout and so on. Branch road often stays in a passive position in order to match the arterial road. The design of the city branch is lack of uniform standard. Unreasonable branch system will affect the coordination effect between arterial road and branch road and reduce the efficiency of road network. This paper researches the shortest length of branch road from three perspective of driver’s psycho- logical feel and convenience of operation and adjustment of speed. Finally,it puts forward some suggestions so as to provide a certain amount of specifications and standards for planning and design.
