Highway real-time traffic monitoring method based on mobile phone signaling

Abstract

The invention discloses a highway real-time traffic monitoring method based on mobile phone signaling. The method comprises the following steps: first, performing wireless network coverage test along a highway, carrying out 'virtual monitoring point' modeling, and obtaining base station positioning reference data along the highway; then, acquiring and parsing Mc interface signaling data, obtaining call behavior information of users, and establishing a single-user traffic event tracking model; and using a highway user recognition model to screen out highway user data, performing correlation matching on the highway user traffic event tracking result and the base station positioning reference data to calculate the average driving speed of highway users, and outputting highway traffic monitoring results according to road sections. According to the method, by introducing network measured data in model correction, the accuracy of highway real-time traffic calculation based on the signaling positioning technology is greatly improved, fusion of the mobile communication technology and intelligent highway management is realized, and convenient and accurate real-time traffic information is provided for highway traffic and management.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for monitoring real-time road conditions of expressways based on mobile phone signaling. Background technique [0002] The current traffic flow information monitoring platform mainly uses GPS information statistics, ground sensing coil information statistics, RFID information statistics, video monitoring systems and other sensing devices and Internet of Things technology applications to obtain traffic flow information. Most of the existing technologies require construction and renovation on roads or the installation of GPS and data return devices on operating vehicles. Considering the construction period, cost and difficulty of construction and renovation, it can only be deployed and deployed on the main roads of big cities at present. However, effective and accurate statistics cannot be achieved for a wider range of non-important roads in large cities, road...

Most of the existing technologies require construction and renovation on roads or the installation of GPS and data return devices on operating vehicles. Considering the construction period, cost and difficulty of construction and renovation, it can only be deployed and deployed on the main roads of big cities at present. However, effective and accurate statistics cannot be achieved for a wider range of non-important roads in large cities, roads in small and medium-sized cities, and expressways.
