The invention discloses a method for querying a traffic record in real time based on ETC Bluetooth communication in the technical field of query records, which comprises a vehicle monitor, a communication system and a controller, the vehicle monitor exchanges data with the controller through the communication system, the vehicle monitor comprises a data acquisition device arranged on an urban road, and the data acquisition device is connected with the controller through a wireless communication module. The system is used for monitoring roads in real time and transmitting obtained monitoring data to a controller, the controller analyzes the monitoring data and evaluates the traffic states of the roads, the roads are firstly combined by obtaining key road combinations, overall judgment is carried out according to the road combinations, and the traffic states of the roads are judged according to the overall judgment. The key degree of the road combination is evaluated by adopting different indexes, and the key degree of the road combination is quantified through the self-defined comprehensive key degree evaluation function, so that the key road combination in the road network is objectively evaluated, and an accurate basis is provided for the system to monitor the road and prevent congestion.

    本发明公开了查询记录技术领域的基于ETC蓝牙通讯实时查询通行记录的方法,包括车辆监控器、通信系统和控制器,所述车辆监控器通过所述通信系统与所述控制器实现数据交换,所述车辆监控器包括设置在城市道路上的数据采集装置,用于对道路进行实时监控,将获取的监控数据传输到控制器,控制器对所述监控数据进行分析,评估道路的交通状态,通过获取关键道路组合,首先对道路进行组合,并且根据道路组合进行整体评判,采用不同指标对道路组合的关键程度进行评判,并通过自定义综合关键程度评估函数对道路组合的关键程度进行量化,客观地评估出道路网络中的关键道路组合,为系统对道路的监控及拥堵预防提供了准确的依据。
