Description

交通信号控制方案切换调整管理系统及方法Traffic signal control scheme switching adjustment management system and method 技术领域Technical field
本发明涉及一种交通信号控制方案切换调整管理系统及方法。The invention relates to a traffic signal control scheme switching adjustment management system and method.
背景技术Background technique
自上世纪90年代开始，国内各级城市均已建设有交通信号控制系统，随着近些年交通拥堵问题的日趋严重，干线及区域协调优化的方式不断被应用普及，因此交通信号控制方案以及控制方式的调度管理成为了交通信号控制研究的基础。Since the 1990s, domestic cities at all levels have built traffic signal control systems. As the traffic congestion problem has become more and more serious in recent years, the method of coordination and optimization of arterial lines and regions has been applied and popularized. Therefore, traffic signal control solutions and Dispatching management of control mode has become the basis of traffic signal control research.
现阶段以海信、莱斯、华通等交通信号机厂商为代表的交通信号控制系统虽可基于手机端/网页端实现交通信号控制方案配置，但存在如下缺点及问题，一来干线/区域协调优化时必须将信号控制方案全部导出，由信控专家或交管部门根据需求分别优化再分别导入各路口交通信号机上，该方法较为复杂且专业性能要求较高；二来针对已配置干线/区域协调的信号控路，某单点路口存在拥堵或其他交通问题需要调整方案时，该路口只能在现状方案的时段上进行配时方案的调整，而为避免其他协调路口控制方案时段不统一对路口秩序带来的影响，需要信控工程师或交管部门用户对其他路口方案进行一并人为更改调整，较为耗时耗力。At this stage, although the traffic signal control system represented by traffic signal manufacturers such as Hisense, Leiss, and Huatong can realize the configuration of traffic signal control schemes based on mobile phones/web pages, it has the following shortcomings and problems. First, trunk/regional coordination When optimizing, all signal control schemes must be exported, optimized by information control experts or traffic control departments according to requirements, and then imported into traffic signals at each intersection. This method is more complicated and requires higher professional performance; secondly, it is for the configured trunk/regional coordination When there is congestion or other traffic problems at a single-point intersection and the plan needs to be adjusted, the timing plan can only be adjusted in the time period of the current plan for the intersection, and to avoid other coordinated intersection control plans, the time period is not unified. The impact of order requires the information control engineer or traffic control department user to make artificial changes and adjustments to other intersection plans, which is time-consuming and labor-intensive.
因此针对现状问题，急需对基准方案和协调优化方案进行电子归档和综合管理，实现方案自动化的调整。Therefore, in view of the current situation, it is urgent to carry out electronic filing and comprehensive management of the benchmark plan and the coordinated optimization plan to realize the automatic adjustment of the plan.
