在一定的假设条件下,建立了环路交通信号联动管理的模型。首先引入交通顺畅程度的评价标准,确定出不同情况下的绿信比,建立了各路口的理想周期模型;之后提出红绿灯高效与否的评价标准;并进一步给出在车流量不同情况下,改变周期的可行性方案;基于综合分析,建立了求解绿灯启动延迟时间的模型,完成了联动管理。最后,利用实验数据对方案进行求解。然后对整体方案模型进行分析评价,并给出了改进方案和进一步的发展方向。
Under certain assumptions, a model for linkage management of loop traffic signals is established. First of all, the evaluation criterion of traffic smoothness is introduced to determine the green ratio in different situations and the ideal periodic model of each intersection is established. Then the evaluation standard of traffic light efficiency is put forward, and then given the change of traffic flow under different circumstances Cycle feasibility of the program; based on a comprehensive analysis, the establishment of a green light start delay time model, completed the linkage management. Finally, the experimental data is used to solve the scheme. Then, the overall scheme model is analyzed and evaluated, and the improved scheme and further development directions are given.
