The invention relates to the technical field of traffic engineering, and provides an array type left-turn secondary signal control method for a large four-way roundabout. The large four-way roundabout comprises an east-direction road, a south-direction road, a west-direction road, a north-direction road and a central roundabout at the intersection position of the four roads, and each entrance lane is provided with a plurality of lanes; a first stop line and a signal control lamp are arranged at the entrance of the entrance lane; a second stop line and a signal control lamp are arranged in front of the conflict position of the traffic flow of each entrance lane and the straight left-turn traffic flow of the opposite entrance lane on the loop; a third parking line and a pre-signal control lamp are arranged behind the first parking line of each entrance lane, no special lane is divided between the first parking line and the third parking line except the right-turn lane, and a left-turn lane, a straight lane and a right-turn lane are sequentially arranged behind the third parking line from left to right. By adopting the scheme, the traffic capacity of the large four-way roundabout can be improved, the average delay of vehicles is reduced, and the congestion is reduced.
本发明涉及交通工程技术领域,本发明提供了一种大型四路环形交叉口阵列式左转二次信号控制方法:大型四路环形交叉口包括东向路、南向路、西向路、北向路、和四条路相交位置的中心环岛,且每条进口道均设有若干车道;在进口道入口处设置第一停车线和信号控制灯;在环道上各进口道车流与对向进口道直行左转车流的冲突处之前设置第二停车线和信号控制灯;再在各进口道第一停车线之后设置第三停车线和预信号控制灯,第一停车线和第三停车线之间除右转车道外不划分专用车道,第三停车线后从左至右依次为左转车道、直行车道和右转车道。采用上述方案,可提高大型四路环形交叉口的通行能力,降低车均延误,减少拥堵。
