Traffic early warning method and device of population movement track

Abstract

The invention provides a traffic early warning method and device of a population movement track. The traffic early warning method comprises the following steps: acquiring telecommunication data of a mobile terminal to obtain longitude and latitude data of three target base stations; calculating distances among the mobile terminal and the three target base stations, and mutual distances among the three target base stations, so as to determine a current position of the mobile terminal; and pre-estimating a future moving position of the mobile terminal according to position information records of the mobile terminal, so as to judge the population density in a monitoring region at a certain moment in the future according to the pre-estimated future moving position of the mobile terminal, and carry out traffic early warning of the population movement track of the monitoring region. According to the method provided by the invention, the cost of early warning of the population density is effectively reduced and the complexity of calculating the population density is reduced; and meanwhile, the change condition of the population density in the monitoring region is obtained according to the moving track pre-estimated by the position data of the mobile terminal, and identification and early warning services can be provided for a population traffic jam condition; and the accuracy of predicating the traffic can be effectively improved.

Description

technical field [0001] The invention relates to traffic flow monitoring technology, in particular to a traffic early warning method and device for population flow trajectory. Background technique [0002] With the rapid development of social economy, the continuous improvement of people's living standards, and the increasing number of public activities, how to ensure the personal safety of public places for public activities and the smooth flow of personnel for large-scale public activities have become important issues for ensuring social public safety and stability. [0003] In the prior art, the following three methods are usually used for early warning of population density in public places: 1. Video surveillance + image recognition technology, by installing video surveillance equipment at the entrances, passages or key positions of public places, collecting surveillance videos, and then passing Image recognition technology, identifying the portraits in it, and then judgi...

Problems solved by technology

[0004] The traffic early warning method and device of the population flow trajectory of the present invention are used to solve the defects of inaccurate and high investment consumption in the prior art population density early warning in public places, and provide a mobile terminal position determination and population flow based on base station data The traffic early warning method of trajectory prediction, which determines the population density by analyzing the base station data of mobile terminals carried by people in the target monitoring area, does not rely on video surveillance equipment, sensors, and GPS positioning services of mobile terminals, etc., which can effectively reduce the population density. The cost of density early warning can reduce the complexity of population density calculation; at the same time, according to the location data of mobile terminals, the trajectory of population movement can be estimated, the change of population density in the monitoring area can be obtained, and the identification and early warning service of traffic congestion can be provided effectively. Improve the accuracy of traffic warning
