Method for obtaining resident travel characteristic parameter based on mobile phone positioning data

Abstract

The invention discloses a method for obtaining a resident travel characteristic parameter based on mobile phone positioning data. The method comprises the following steps of: (1) collecting mobile phone positioning data; (2) filtering the mobile phone positioning data, matching the mobile phone positioning data to traffic zones, and obtaining the matched mobile phone positioning data; (3) using users as units, ordering the matched mobile phone positioning data in one day by time, merging the continuous data in the same one traffic zone into one piece, and obtaining mobile phone positioning pretreatment data; (4) according to the number of emerged pieces and influence duration, judging residing points, restoring a travel path between two residing points, and obtaining the travel distance and the travel speed, and then obtaining a travel log table of all users; (5) on the basis of the matched mobile phone positioning data, statistically obtaining a place of residence and workplace result table; and (6) and conjointly analyzing the travel log table and the place of residence and workplace result table, and obtaining resident travel characteristic parameters. The method has the characteristics of low cost, large sample quantity, high precision and high time validity.

Description

technical field [0001] The invention relates to the technical field of traffic information collection and processing, in particular to a method for acquiring travel characteristic parameters of residents based on mobile phone positioning data. Background technique [0002] The travel survey of residents refers to a comprehensive investigation of a certain proportion of citizens in the survey area for a day's travel, in order to understand the total amount of urban traffic trips, main sources of attraction, travel purposes, mode structure, time-space distribution, travel time consumption, travel time, etc. Travel characteristics of residents such as distance. [0003] The travel survey of residents is an important basic work of urban comprehensive transportation planning. It is the main means to grasp the characteristics and laws of urban transportation. The law of evolution plays a key role and has extensive application value for the study of social and economic development...

AI Technical Summary

Problems solved by technology

[0005] (1) It requires a lot of manpower and material resources, and the development cycle is long (from planning to implementation)

[0006] (2) Due to the huge cost, the survey interval is long (generally more than 5 years), and the data update is not timely enough

[0007] (3) The accuracy of the results is restricted by many factors, including sample size (the sample rate is generally within 5% of the urban population), sample deviation, the responsibility of the investigators, the degree of cooperation of sample users, the accuracy of input data and verification data, etc. The results are often less accurate

However, there are still a number of disadvantages to using GPS devices for traffic surveys:

[0009] (1) Need to purchase additional GPS equipment

[0010] (2) Data cannot be collected indoors, under bridges, subways, etc.

[0011] (3) The sample size is small and cannot be carried out on a large scale

[0013] Existing technologies that use mobile phone positioning data to extract some travel characteristic parameters, such as the Chinese invention patent application number 200910092031.3, only obtain the start and end points of travel, but cannot comprehensively reflect the overall characteristic parameters of the residents' travel survey. The method needs to use " However, in the actual communication process, data loss occurs from time to time, which seriously affects the quality of the analysis results and makes the method very limited in practical applications.
