设置辅路的城市主干路交叉口设计方法
|
摘要
由于城市主干路存在着大量的通过性交通,一般要求较高的通行速度,若沿线所有进出口均直接进入主车道,将严重影响主车道的通行功能。故对于交通量大的干线性城市主干路,通过设置辅路对沿线进出口起到控制和集散作用以保证沿线主线交通的快速通行。设置辅路的道路的交叉口设计较为复杂,设计成功与否直接影响整条道路的通行功能。现结合工程实例,对设置辅路的城市主干路交叉口设计进行探讨,希望能对类似工程起到借鉴作用。
Because there is a lot of transit traffic on urban trunk roads, generally the higher speed is required.If all entrances and exits along the line enter the main lane directly, the traffic function of the main lane will be seriously affected. Therefore, for the trunk linear urban roads with large traffic volume, the auxiliary roads are set up to play the role of control, collection and distribution for the entrances and exits along the line in order to ensure the rapid traffic of the main trunk road along the line. The design of intersections of road with auxiliary road is more complex. The design quality will directly affect the traffic function of the whole road.Combined with the engineering examples, this paper discusses the design of intersections of the urban trunk roads with the auxiliary roads, which can be referred for the similar projects.
