摘要:

为了实现城市交通优化控制,提高城市道路通行能力,本文首先提出了城市交通多线路协调控制优化仿真模型,并在此模型基础上给出了时空相位演化算法和改进的遗传优化算法(GA),然后总结了城市交通多线路协调控制优化仿真系统的基本结构、数据结构和技术路线,并完成了城市交通多线路协调控制优化仿真系统设计与开发。该仿真系统结构简单,建模方便,可以适用于任何城市交通优化控制,解决了城市交通多线路协调控制(多线路绿波带)难题。通过对佛山市某路网的实际建模与仿真,该系统取得了较好的交通优化效果。

Abstract:

In order to optimize urban traffic control to ease urban traffic, a multiline coordination control optimization and simulation model of urban traffic is  proposed. And the algorithm of spacetimephase evolution and the improved genetic algorithm (GA) based on the model are  given also. After summing up the system architecture, data structure and technical course, a multiline coordination control optimization and simulation system of urban traffic were completed. The simulation system and its modeling are simple, and it can be applied to any optimization of urban traffic control, in order to solve the problem of multiline coordination of urban traffic control (multiline green wave).By the actual modeling and simulation on a road network of Foshan city, the system achieves good results on urban traffic control optimization.
