Abstract

The invention discloses a WIFI signal-based macro traffic flow detection algorithm. According to the algorithm, a detection device system is deployed along a traffic road; the detection device systemincludes a plurality of sub-networks; each sub-network includes one host and a plurality of extension sets; the extension sets (single detection devices) acquire broadcast type data packets through awireless passive sensing mode, 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 datapackets marked with the extension set labels to the host, wherein the broadcast type data packets are randomly sent to an ambient environment by mobile terminal devices based on a WIFI protocol; thehost 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 detected through data analysis.

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 kinds of 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 damage the road surface. Theref...
