Abstract

The invention discloses a traffic section flow speed prediction algorithm based on a WIFI (Wireless Fidelity) signal. The traffic section flow speed prediction algorithm comprises the following steps:deploying a predicated equipment system along a traffic road, wherein the predicated equipment system comprises a plurality of sub-networks and each sub-network comprises a host and a plurality of extensions; acquiring a broadcasting data packet, which is sent by mobile equipment based on a WIFI signal protocol in an ambient environment, by the extensions based on a WIFI protocol through a wireless passive perception mode; screening a data packet carrying ID (Identity) information of mobile terminal equipment and searching; after marking extension labels, uploading the extension labels to thehost; carrying out uniform storage on the collected data by the host and marking time labels; uploading the collected data into a data server and storing; analyzing the data to obtain a road sectionflow speed evaluation and predication result. According to the traffic section flow speed prediction algorithm disclosed by the invention, data mining and analysis of the acquired data of a mobile terminal are realized and the traffic section flow speed prediction algorithm can be applied to detection of a traffic section flow speed.

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...
