| 摘 要： | 针对当前城市干道瓶颈交叉口交通拥堵状况,从信号控制角度提出了1种红波双向协调控制模型,对于缓解此类问题具有现实意义.模型是在流量均分思想和绿波协调控制时距图分析方法基础上建立的1种双向协调控制模型,能够针对干道瓶颈交叉口上下游交通流不同的交通控制需求分别实施红波协调控制和绿波协调控制,并通过引入红波控制参数,可以满足不同的交通控制策略需求.以佛山市顺德区南国西路为案例,通过对Vissim仿真评价数据进行协调前后对比分析,结果表明模型能够有效减小瓶颈交叉口排队长度39.48%,缩短行程时间22.01%,验证说明了模型的有效性.

| Abstract: | With urban intersections acting as congestion bottlenecks, this paper proposes a red wave two-way coor- dination control model, which may have a good potential of mitigating such congestion. The model is a two-way flow co- ordinated control model, which is developed based on the Green Wave coordinated control space time chart and equalizing traffic flows. The proposed method can implement either red wave or green wave coordinated control and it can choose different red wave control parameters in order to meet different traffic conditions upstream/downstream. By using Nanguo West Road of Shunde District, City of Foshan as the case study, a before and after study is carried through a Vissim sim- ulation analysis. The study results show that the model can effectively reduce the bottleneck queue lengths at the intersection by 39. 480/oo, and the time delay by 22.01%. Thus, the effectiveness of the model is proved. |
