摘要:
为了消除环形交叉口的冲突点、减少交织区车流量和左转与调头车辆行驶距离,在现有卫星岛式环形交叉口的基础上提出:将单一环形交叉改为内外双环形交叉;改变卫星岛式环形交叉口的分流方式.据此进行了卫星岛式内嵌双环形交叉口概念设计,且基于两者对比及模拟分析发现:在造价和用地相当的情况下,卫星岛式内嵌双环形交叉口不但可以保留卫星岛式环形交叉口带来的优势,且能消除其在车辆由卫星岛驶入中心岛时产生的冲突点,同时通过不同的分流方式避免了交织段车流量集中、车辆绕中心岛顺时针行驶(与常规驾驶习惯不符)以及部分路段对向行驶的问题,从而提高路段通行能力.
Abstract:
In order to eliminate the conflict points of roundabouts, reduce the traffic flow in the weaving area and the driving distance of left-turn and U-turn vehicles, it is proposed on the basis of the existing satellite island roundabouts: change a single roundabout to an inner and outer double roundabout; change the satellite The diversion method of the island roundabout. Based on this, the conceptual design of the satellite island embedded double roundabout is carried out. The satellite-shaped intersection can not only retain the advantages brought by the satellite-island roundabout, but also eliminate the conflict points when vehicles drive from the satellite island to the center island. Vehicles drive clockwise around the central island (contrary to conventional driving habits) and some road sections drive in the opposite direction, so as to improve the traffic capacity of the road section.
