The invention discloses a public traffic supply-demand detection and prediction system and method. The system comprises a processing device, a detection device, a roadside communication device, a bus-mounted device and a taxi-mounted device, wherein all devices are combined to form a wireless sensor network; the detection device or the roadside communication device can be connected in a wireless mode, and can be connected with the processing device in a wireless mode, so that information of the detection device or the roadside communication device can be transmitted to the processing device in a multi-hop mode; the bus-mounted device and the taxi-mounted device can be only communicated with the roadside communication device, and access the network in a dynamic mode.
Description
technical field [0001] The invention belongs to the technical field of urban traffic control, in particular to a system and method for detecting and predicting the state of public transport supply and demand. Background technique [0002] With the continuous expansion of the city, various large-scale activities that may cause crowds are increasing, and there is a great demand for transportation capacity such as buses, subways, and taxis around commercial centers, transportation hubs, and stadiums. Timely detection and prediction of the supply and demand status of public transportation around the site, in order to take effective measures to dispatch traffic capacity in time, will play an important role in alleviating urban traffic congestion and improving the urban environment. [0003] Invention patent application "method and device for crowd gathering detection" (application number: 201210071625.8), "a crowd density detection method and device" (application number: 20091023...
