基于事件驱动的城市交通信号控制方法

随着城市交通信号控制需求的不断提高，各种新智能交通信号控制算法不断被提出和改进。然而受到现有设备固有控制方式和不同类型信号机无法协同的局限，智能控制算法多停留在理论研究和仿真试验阶段。为实现不同交通信号控制算法的统一模式，提出一种基于事件调度的交通信号控制模型（ED-Model）。该模型将控制算法拆分为状态检测与请求调度两大功能模块，通过扩展后状态检测的抽象概念事件统一了系统输入，通过交通信号控制请求调度系统实现系统输入的响应模式，从而实现各类交通信号控制算法的统一实现架构。分析表明，ED-Model可以有效地实现当前各类常规控制需求，并对其他各类智能算法的移植实现具有较好的可扩展性。

Urban Traffic Signal Control Method Based on Event Scheduling

Because of the increasing requirement of the traffic signal control, many new intelligent signal control algorithms are presented. However, limited by the traditional equipment and the difficulty for different traffic signal machine integration, intelligent signal control algorithms stay in theoretical research and computer simulation phase. To obtain unified pattern of different control algorithms, the article presented a new traffic signal control model based on event scheduling. This model divided the algorithms to state inspection module and request scheduling module, and unified the input of system by extended state inspection concept. The article obtained response model of system input by request scheduling system. The analysis result shows that ED-model can satisfy general control requirements, and it has good portability for other intelligent signal control algorithms.
