The invention discloses a method and system for calculating the traffic congestion degree based on radio frequency identification. The method comprises the steps of motor vehicle identification, motor vehicle number acquiring and congestion degree acquiring. According to the step of motor vehicle identification, a reader-writer is used for conducting automatic identification on motor vehicle license plate information carried in a vehicle-mounted radio frequency identification label, and related identification information is recorded. According to the step of motor vehicle number acquiring, the number of times for the reader-writer to identify motor vehicles and the number of the motor vehicles which actually pass through the working area of the reader-writer within a certain period are accumulated. According to the step of congestion degree acquiring, the normal traffic constant flow under the normal condition is acquired, the normal traffic constant flow and the number of the times for the reader-writer to identify the motor vehicles are compared with the number of the motor vehicles which actually pass through the working area of the reader-writer, the traffic congestion degree is acquired in real time, and a management person or system is timely informed of the congestion condition.
Description
technical field [0001] The invention relates to a monitoring method, in particular to a method and system for monitoring the degree of road traffic congestion by using radio frequency identification in intelligent traffic applications. Background technique [0002] With the development of social economy and the improvement of urban modernization level, problems such as traffic congestion have become common problems faced by various cities. If the degree of traffic congestion on urban roads can be perceived in a timely manner, the traffic management department can carry out reasonable traffic flow control, improve transportation efficiency, and ensure traffic safety. [0003] In the current situation, the means of sensing the degree of road traffic congestion include ground sensing coils, radar speed measurement, video surveillance, etc. Using the ground sense coil to sense the degree of traffic congestion requires road construction, which will affect the road and traffic. ...
