The invention discloses a traffic flow prediction method and system and an urban traffic signal machine control method, and relates to the field of urban traffic management, and the method comprises the steps: obtaining multi-mode perception data, matching map lane information with the multi-mode perception data, and obtaining a time series data set of each lane; analyzing and predicting the time sequence data set to obtain fixed vehicle flow and random vehicle flow of each single intersection; performing weighted average processing on the fixed vehicle flow and the random vehicle flow to obtain the intersection predicted vehicle flow of each single intersection; judging whether the global predicted traffic flow meets a global constraint condition or not according to the intersection predicted traffic flow, the spatial topological relation between the single intersections and the upstream and downstream driving-out and driving-in relation of the intersections; and if the global predicted traffic flow meets the global constraint condition, taking the global predicted traffic flow as a prediction result, so that the problem of low detection accuracy of a traditional method is solved, the traffic flow can be comprehensively and accurately detected, and the detection accuracy is improved.

    本发明公开一种车流量预测方法、预测系统及城市交通信号机控制方法,涉及城市交通管理领域,包括:获取多模态感知数据,将地图车道信息与多模态感知数据进行匹配,获得每个车道的时间序列数据集;对时间序列数据集进行分析预测,获得每个单路口的固定车辆流量与随机车辆流量;对固定车辆流量与随机车辆流量进行加权平均处理,获得每个单路口的路口预测车流量;根据路口预测车流量、单路口之间的空间拓扑关系以及路口上下游驶出驶入关系,判断全局预测车流量是否满足全局约束条件;若全局预测车流量满足全局约束条件,则将全局预测车流量作为预测结果,解决了传统方法检测准确率低的问题,可以全面准确地对车流量进行检测,提高了检测准确率。
