适于双周期的干道绿波信号协调控制模型

针对现有双周期干道绿波信号协调控制方法存在的不足，首先推导了适于双周期 协调控制的等式约束条件，其次详细分析了现有研究成果存在的缺陷，再次以双向权重绿波 带宽之和最大为优化目标，建立了适于双周期协调控制的绿波协调控制模型；最后以义乌市 望道路为例，利用VISSIM 仿真平台对比本文模型与改进MULTIBAND模型生成的协调控制 方案之间的优劣.仿真结果对比表明，相比于改进MULTIBAND模型，本文模型生成的协调控 制方案在高、中、低交通需求下均能够有效减少平均延误时间与停车次数，从而验证了本文所 建模型的有效性与实用性.

Arterial Signal Coordination Control Model for Double-cycle Signal Control

In order to solve the deficiency of the existing arterial signal coordination control methods based on double-cycle, Firstly, a new loop integer constraint suitable for double-cycle is derived. Secondly, the deficiencies of the existing methods are analyzed thoroughly. Thirdly, a double-cycle signal coordination model with maximizing the sum of weighting bi- directional progression bandwidths is established. Finally, taking Wangdao road in Yiwu city as an example, the VISSIM simulation software has been used to make contrastive analysis of advantages and disadvantages between the signal coordination plan generated by the established model and the signal timing plan generated by revised MULTIBAND model. The simulation results show that compared to the signal timing plan generated by revised MULTIBAND model, the signal coordination plan generated by the proposed model can efficiently decrease the average delay and stops in high, medium and low traffic demand, which indicates that the proposed model is effective and practicable.
