The invention provides a traffic flow data prediction processing method and system in order to solve the problem of low traffic flow prediction accuracy caused by complex traffic flow space-time correlation in the prior art. The method comprises the steps of obtaining intersection parameters and historical traffic data, performing smooth fusion on the data, predicting traffic in an abnormal period, and judging whether a historical scheme meets a vehicle release requirement and outputs a period, a period and green light duration of each phase, and the system comprises a monitoring end and a processing end which are connected through wireless communication, according to the method, the change trend of the flow is calculated through the historical data, the original flow of the abnormal data is predicted, the problem that the traffic flow prediction accuracy is not high in the prior art is solved, and the finally obtained result is more accurate.
本发明为解决现有技术中交通流量时空相关性复杂导致的交通流量预测准确性不高的问题,提供一种交通流量数据预测处理的方法及系统,方法上包括获取路口参数及历史流量数据、对数据进行平滑融合并预测异常时段流量、判断历史方案是否满足车辆放行需求和输出时段、周期和各相位绿灯时长,系统上包括通过无线通信连接的监测端和处理端,本发明通过历史数据计算流量的变化趋势,预测出异常数据原本的流量,解决了现有技术中交通流量预测准确性不高,最终得到的结果会更加精确。
