The invention discloses an automatic traffic management system based on digital twinning, and particularly relates to the field of digital twinning. Comprising a road map drawing module, a road information import module, a road area monitoring equipment setting module, a road area division module, a data acquisition module, an automobile and pedestrian data preprocessing module, a secondary data acquisition module, a secondary data processing module, a data analysis module, a density characteristic value judgment module and a traffic light control module. The method comprises the following steps: drawing a to-be-measured map, inputting the map into a digital twin system to generate a road map, collecting the number of automobiles passing through an intersection in each monitoring sub-region and the data of pedestrians passing through the intersection, and calculating a first metric value through the collected data; collecting the date in each monitoring sub-area, the weather at the intersection and the average speed of passing of the automobile again, feeding back the data to the intelligent traffic digital model, and calculating an environment characteristic value through the data; the first measurement value and the environment characteristic value are sorted and analyzed to obtain a density characteristic value, then the density characteristic value and a density characteristic value threshold value are compared to output different instructions, the different instructions are conveniently output to a traffic light control module, and corresponding measures are taken according to the different instructions.

    本发明公开了一种基于数字孪生的自动化交通管理系统,具体涉及数字孪生领域,包括道路地图绘制模块、道路信息导入模块、道路区域监测设备设置模块、道路区域划分模块、数据采集模块、汽车和行人数据预处理模块、二次数据采集模块、二次数据处理模块、数据分析模块、密度特征值判断模块、红绿灯控制模块,本发明通过绘制待测地图并将地图输入到数字孪生系统中生成道路地图,采集个监测子区域内路口通过的汽车数量和行人通过的数据,再通过采集的数据计算得出第一度量值;再次采集各监测子区域内日期,路口的天气和汽车通过的平均速度,再将数据反馈到智慧交通数字模型中,通过数据计算得出环境特征值;将第一度量值和环境特征值整理分析得出密度特征值,再将密度特征值和密度特征值阈值进行对比输出不同指令,以便输出到红绿灯控制模块,根据不同指令做出相应措施。
