Alpha-shaped urban interchange with small steering angle and urban interchange group combination method
The invention discloses an alpha-shaped urban interchange with a small steering angle, which comprises two mutually staggered two-way roads, and inner side lanes of the roads are straight lanes; the middle lane of the rear half section of the third road is connected with a first sinking lane through a first downhill section, and the first sinking lane is communicated with the middle lane of the rear half section of the first road through a first left-turn lane; the middle lane of the rear half section of the fourth road is connected with a second sinking lane through a second downhill section, and the second sinking lane is communicated with the middle lane of the rear half section of the second road through a second left-turn lane. The invention further discloses an urban interchange group combination method which comprises at least two alpha-type urban interchange bodies with small steering angles, and the adjacent urban interchange bodies are connected through the urban road grids. According to the alpha-shaped urban interchange with the small steering angle and the urban interchange group combination method, the traffic flow of a crossroad is increased by four times through a single interchange; the urban grid road network interchange group is combined, and the peak traffic flow of the urban road network is exponentially improved.
本发明公开了一种小转向角的α型城市立交，包括两条相互交错的双向道路，各道路的内侧车道均为直行车道；第三道路后半段的中部车道通过第一下坡段连接有第一下沉车道，第一下沉车道通过第一左转车道与第一道路后半段的中部车道连通；第四道路后半段的中部车道通过第二下坡段连接有第二下沉车道，第二下沉车道通过第二左转车道与第二道路后半段的中部车道连通。还公开了一种城市立交群组合方法，包括至少两个小转向角的α型城市立交，相邻城市立交之间通过城市道路网格连接。本发明提供的小转向角的α型城市立交以及城市立交群组合方法，单个立交四倍提升十字路口通行流量；组合成城市方格路网立交群，指数级提高城市路网峰值通行流量。
