Embodiment Construction

[0037] Such as figure 1 As shown, a method for estimating population exchange volume based on signaling data combined with dynamic thresholds to determine travel validity includes the following steps:

[0038] 1. Calculate the stay time of travelers at each base station.

[0039] The residence time of a base station refers to the time during which the traveler communicates with the base station for signaling data.

[0040] Among them, the method for calculating the stay time of travelers at each base station includes:

[0041] 11) Sort the signaling data generated by the traveler in a day by time, mark the last record of the traveler’s communication in each base station, and record the time of obtaining this record (field start_time) as the departure time t when the traveler leaves the base station end ;

[0042] 12) Calculate the departure time of the previous base station of the adjacent base station in the travel chain record of the traveler Departure time from the next ...

Abstract

The invention discloses a population exchange amount estimation method for judging travel effectiveness based on signaling data and in combination with a dynamic threshold value, which can utilize thecollected signaling data generated during daily operation of a mobile phone network operator to obtain the population exchange amount information with different spatial scales and time scales necessary for traffic planning at low cost. According to the invention, the population exchange quantity of each level is obtained by using the signaling data, the method can be widely applied to the urban planning and traffic planning and management, and the limited public resources can be more reasonably and efficiently distributed. Besides, compared with a traditional mode of collecting population exchange data in a questionnaire and the like, the population exchange amount estimation method based on the signaling data is low in cost and high in accuracy and is one of the innovative representations of an urban traffic planning method in the big data era.

Description

technical field [0001] The invention relates to the technical field of traffic big data, in particular to a method for estimating population exchange volume based on signaling data combined with a dynamic threshold to determine travel effectiveness. Background technique [0002] In recent years, my country's economy has developed rapidly, and the number of motor vehicles has increased significantly. In 2010, the number of cars in my country was about 70 million. According to the data released by the Traffic Management Bureau of the Ministry of Public Security on July 16, 2018, as of the end of June 2018, the number of motor vehicles in the country reached 319 million. The rapid increase in the number of motor vehicles has brought severe challenges to my country's urban road traffic planning, and traffic congestion is becoming more and more serious. At present, the main measure to control traffic congestion in my country is to expand the road infrastructure, and its governan...
