The invention discloses an urban traffic flow analysis and management method, relates to the technical field of traffic management and information, and solves the technical problems that an average vehicle speed deviation value and vehicle position data are lacked to evaluate a lane congestion condition and analysis of traffic flows of different weather types is lacked. The method includes the following steps that the number, types, timestamps, noise and image data of vehicles are collected through a collection system; constructing a cloud platform, transmitting the data to a cloud server, and processing the data through a Spark Streami ng stream processing technology to obtain a vehicle type noise weighted calculation value and a lane congestion evaluation value; through analysis of historical and real-time data, a public transport line length deviation value, a weather type assignment value and a traffic lane number value are collected to obtain an influence factor comprehensive weighted calculation value, and a traffic operation data value is constructed by combining a vehicle type noise weighted calculation value and a lane congestion evaluation value. And carrying out grade division on the predicted traffic jam condition and sending out a corresponding early warning signal.
本发明公开了一种城市车流量分析管理方法,涉及交通管理和信息技术领域,解决了缺少平均车速偏离值和车辆位置数据对车道拥堵情况进行评价,缺乏对不同天气类型的车流量进行分析的技术问题,包括以下步骤:通过采集系统采集车辆数量、类型、时间戳、噪声和图像数据;构建云平台,将所述数据传输到云服务器,通过Spark Streami ng流处理技术对数据进行处理,得到车型噪声加权计算数值和车道拥堵评价值;通过对历史和实时数据分析,采集公共交通线路长度偏离值、天气类型赋值和行车道数量值得到影响因素综合加权计算数值,结合车型噪声加权计算数值和车道拥堵评价值构建交通运行数据数值,对预测的交通拥堵情况进行等级划分并发出对应预警信号。
