The invention relates to a roundabout passage and signal control method based on shift left turn, which comprises the following steps of: 1, setting the number of lanes and lane functions of each entrance of a roundabout according to the geometric conditions of an urban trunk road and the traffic flow distribution of each entrance lane of the roundabout, and planning traffic marking lines; drawing a traffic channelization scheme diagram of the roundabout; 2, determining the position of a left shift of the roundabout and the length of a shift section; thirdly, an inner side loop road and an outer side loop road of the roundabout are arranged; 4, determining a parking line and a parking area of left-turn vehicles on the inner side ring road of the roundabout; 5, setting a traffic signal lamp; sixthly, traffic signs are set; and 7, determining a signal phase scheme to obtain a roundabout traffic and signal control method. According to the method, the roundabout vehicles can be released only through two phases, the passing efficiency is high, the right of way is reasonably distributed at the shifting position outside the roundabout, and vehicle conflicts are reduced through signal control.
本发明涉及一种基于移位左转的环形交叉口通行及信号控制方法,包括如下步骤:第一步、根据城市干道几何条件及环形交叉口各个进口道交通流量分布,设置环形交叉口各进口的车道数量及车道功能,规划交通标线,绘制环形交叉口交通渠化方案图;第二步、确定环形交叉口左转移位的位置及移位段长度;第三步、设置环形交叉口的内侧环道与外侧环道;第四步、确定环形交叉口内侧环道左转车辆的停车线和停车区域;第五步、设置交通信号灯;第六步、设置交通标志;第七步,确定信号相位方案,得出环形交叉口通行及信号控制方法。本发明仅需两个相位就可以完成环岛车辆的放行,通行效率高,在环道外移位处合理分配路权,通过信号控制,减少了车辆冲突。
