The invention discloses a WIFI signal-based macro traffic flow prediction algorithm. According to the algorithm, a prediction device system is deployed along a traffic road; the prediction device system includes a plurality of sub-networks; each sub-network includes one host and a plurality of extension sets; the extension sets acquire broadcast type data packets through a wireless passive sensingmode, screen out data packets carrying mobile terminal device ID information, retrieve the data packets, mark the data packets with extension set labels, and transmit the data packets marked with theextension set labels to the host, wherein the broadcast type data packets are randomly sent by mobile terminal devices to an ambient environment; the host stores collected data in a unified manner, marks the data with time labels, and uploads the data to a data server for storing the data; and macro traffic flow is evaluated and predicted through data analysis. With the WIFI signal-based macro traffic flow prediction algorithm of the invention adopted, the data mining and data analysis of the acquired data of the mobile terminals can be realized. The algorithm can be applied to macro trafficflow prediction.
Description
technical field [0001] The invention belongs to the mobile Internet technology, and in particular relates to the improvement of macroscopic traffic information monitoring algorithms. Background technique [0002] Traffic flow data is an important source of information for the traffic operation dispatching command system, which can provide decision-making basis for command dispatching, traffic flow control and traffic guidance. There are many existing traffic flow detection technologies, which can be divided into contact detection methods and non-contact detection methods according to the installation method. Among them, the contact detection technology includes piezoelectric, pressure tube detection and loop coil detection. The main disadvantage of this technology is that the service life of the detector is short due to the rolling of the vehicle on the road. When the detector is deployed, it is necessary to interrupt the traffic and destroy the road surface. Therefore, it ...
