The invention relates to a GPS (Global Position System) based traffic flow and road jamming detection system, comprising vehicle-mounted terminals arranged on monitoring vehicles, a server used for receiving information of the vehicle-mounted terminals and carrying out congestion calculation, wherein the vehicle-mounted terminals are in communication connection with the server through a wireless communication network, and each vehicle-mounted terminal comprises a GPS module, a first communication module, a display module and an information processing module; the server comprise a congestion state calculation module and is used for acquiring real-time traffic information through a congestion function according to coordinate information sent back by different vehicle-mounted terminals, and the congestion function is adopted for calculating congestion degrees of different rod sections, if the congestion degree is larger than a preset congestion degree threshold, a congestion state is judged to be, and otherwise, a smooth state is judged to be; and a second communication module is used for sending traffic states of different road sections to the vehicle-mounted terminals. The invention has the advantages of low cost, strong practicability and easy popularization.
Description
technical field [0001] The invention belongs to the field of traffic flow monitoring systems, in particular to an urban traffic flow monitoring system. Background technique [0002] Along with the increase of traffic flow in cities and highways, traffic jams occur from time to time. For the convenience of travel, people often hope to know the traffic flow situation of each road section they pass through, so as to adjust their driving route, avoid the road section with relatively congested traffic, and ensure that they reach their destination in a relatively short period of time. At present, in order to meet the needs of people traveling, the method adopted is often to place a camera for monitoring traffic conditions and vehicle violations on each road section. The camera can transmit the collected image information to the monitoring center, and the monitoring center will receive The image information received is automatically recognized, so as to obtain the traffic conditio...
