The invention discloses a traffic coordination passing parameter calculation method based on Flink, and the method is based on an Flink streaming processing engine, and a vehicle route statistics module, a vehicle route extension statistics module, a route passing parameter statistics module and a route passing parameter extension statistics module are operated on the engine. The engine is used for carrying out vehicle statistics on all checkpoint passing vehicle data within an estimated time range according to lines in a continuous passing line configuration table at intervals, and outputting time and space parameters when vehicles pass through intersections on the lines in combination with signal machine lamp state data. And counting passing parameters of the line according to the vehicle passing time and space parameters, and providing the counted passing parameters of the line for a user or other systems for decision analysis so as to realize traffic coordination. According to the method, an Flink streaming processing engine is adopted, mass bayonet data can be subjected to statistical analysis in real time, and the value existing in the data can be mined in real time.
本发明公开了一种基于Flink的交通协调通行参数计算方法,该方法基于Flink流式处理引擎,在该引擎上运行车辆线路统计模块、车辆线路扩展统计模块、线路通行参数统计模块、线路通行参数扩展统计模块;利用该引擎,对于估算的时间范围内的所有卡口过车数据,按照连续经过线路配置表中的线路,每隔一段时间进行车辆统计,结合信号机灯态数据,输出车辆通过线路上交叉口的时间和空间参数,根据车辆通行的时间和空间参数统计线路的通行参数,将统计到的线路通行参数提供给用户或其他系统进行决策分析,以实现交通协调。本发明采用Flink流式处理引擎,能够实时对海量卡口数据进行统计分析,实时挖掘数据中存在的价值。
