Abstract

The invention discloses a traffic road information detection system based on a cellular network and a detection method thereof, and mainly solves the problems of high cost, poor traffic flow information accuracy of the prior art. The detection system comprises a vehicle-mounted terminal, a cell base station and an assistant handheld terminal, wherein the cell base station is provided with a traffic information extraction module and a traffic information processing module. The vehicle-mounted terminal transmits the acquired traffic information of a monitored vehicle to the cell base station through the existing cellular network. At the same time, the handheld terminal also transmits road situation information observed by an authorized user to the cell base station, the cell base station utilizes the received traffic information to judge the congestion state of a road section by calculating the congestion function value of the road section and finally the cell base station transmits the information of the congestion state of the road section to the nearby vehicle-mounted terminal in a form of broadcasting. The traffic road information detection system based on the cellular network and the detection method disclosed by the invention have the advantages of low cost, high practicability and easiness in popularization and application.

Description

technical field [0001] The invention belongs to the technical field of information detection and relates to a traffic flow monitoring system, which is used to realize the monitoring of traffic flow and road congestion state. Background technique [0002] With the development of urbanization and the improvement of people's living standards, the number of cars has increased year by year, resulting in a large increase in highway traffic flow and more and more frequent traffic jams. For the convenience of travel, people always hope to know the traffic flow situation of each road section they pass, so as to adjust their driving route, avoid congested road sections, and reach their destination as soon as possible. [0003] At present, for the monitoring of traffic flow, the method adopted is mainly to install cameras on each road section to monitor traffic conditions and vehicle violations, and the cameras will send the collected image information to the monitoring center, and the...
