The invention relates to the technical field of traffic monitoring, in particular to a Beidou-based traffic flow real-time monitoring method and system, and the method comprises the following steps: receiving signal data and analyzing a signal source based on a Beidou short message communication terminal, extracting vehicle positioning information and road occupation information in vehicle operation state data, and transmitting the vehicle positioning information and the road occupation information to a Beidou short message communication terminal; and analyzing the vehicle speed and the traffic flow density, and carrying out matching operation on the analysis result and the road section number to obtain traffic flow state data. According to the method, vehicle positioning and road occupation information is extracted through signal analysis, efficient acquisition and integration of traffic state data are realized, road section numbers are matched to improve data space precision, traffic pressure is reflected, dynamic flow analysis is supported, adjacent road section data are integrated, abnormal areas are positioned, shunting paths and proportions are optimized, and emergency response efficiency is improved. Real-time regulation and control of traffic flow are realized through dynamic pushing, the flexibility and responsiveness of traffic operation are enhanced, and the monitoring precision and the road network operation efficiency are comprehensively improved.

    本发明涉及交通监测技术领域,具体为基于北斗的交通流量实时监测方法及系统,包括以下步骤:基于北斗短报文通信终端,接收信号数据并对信号源进行解析,提取车辆运行状态数据中的车辆定位信息与道路占用信息,分析车辆速度与车流密度,将分析结果与路段编号进行匹配运算,得到交通流量状态数据。本发明中,通过信号解析提取车辆定位与道路占用信息,实现交通状态数据高效获取与整合,匹配路段编号提升数据空间精度,反映通行压力并支持动态流量分析,整合相邻路段数据,定位异常区域并优化分流路径与比例,提升应急响应效率,通过动态推送实现交通流量实时调控,增强交通运行的灵活性与响应性,全面提升监测精度和路网运行效率。
