区域交通优化服务是交通信号控制系统的重要子系统,能否动态地调整优化配置参数是影响优化服务效果的重要因素,如在利用遗传算法解决区域交通优化配时中的多目标优化问题时,常常遇到优化配置参数不易调整,进而影响了优化算法使用效果的问题。本文设计出一种区域交通优化信号配时数据结构,并开发了相应软件,使得修改、保存优化配置参数等操作更简便。结果表明,设计的数据结构和软件可使交通信号控制优化算法的执行效果更好,其用于区域交通优化服务是稳定可靠的。
Regional traffic optimization service is an important sub-system of traffic signal control system. Whether it can dynamically adjust and optimize the configuration parameters is an important factor that affects the optimization of service performance. For example, when solving the multi-objective optimization problem of regional traffic optimization with genetic algorithm, Often encountered optimization of the configuration parameters is not easy to adjust, thus affecting the optimization algorithm to use the effect of the problem. In this paper, a kind of regional traffic optimization signal timing data structure is designed, and the corresponding software is developed to make it easier to modify, save and optimize the configuration parameters. The results show that the designed data structure and software can make the traffic signal control optimization algorithm perform better, and it is stable and reliable for the regional traffic optimization service.
