Embodiment Construction

[0023] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0024] A statistical method for personnel travel parameters based on mobile phone signal data, the specific steps are as follows:

[0025] (1) Establish a virtual sensor network;

[0026] (2) Obtain real-time signal data sent by all mobile phones within a fixed time interval T from the mobile phone network;

[0027] (3) Preprocessing the data obtained in step (2), including deleting invalid data, processing data generated due to base station drift, and analyzing and processing mobile phone data that has not generated signals for a long time;

[0028] (4) Read the city electronic map information from the urban zoning database, superimpose all the mobile phone data of the i-th mobile phone obtained in the previous step on the electronic map, and obtain the moving track of the i-th mobile phone in the electronic map, which is defined as the first El...

Abstract

The invention discloses a statistical method for personnel travel parameters based on mobile phone signal data. The main steps are: establishing a virtual sensor network, obtaining real-time signal data sent by all mobile phones within the time interval from the mobile phone network at a fixed time interval; and real-time signal data to obtain the user's electronic footprint; judge the user's travel and whether there is a secondary trip according to the electronic footprint; then calculate the travel distance according to the road network matching; finally obtain the travel OD matrix of the entire statistical area and related travel parameters. The present invention fully relies on the existing mobile communication network resources and utilizes the information in the existing mobile communication network to complete a large-scale investigation of traffic travel characteristics in the city in a short time, and at the same time, the initial investment is relatively small, the data coverage is large, The data precision is high.

Description

technical field [0001] The invention relates to the technical field of traffic planning and management methods, in particular to a statistical method for personnel travel parameters based on mobile phone signal data. Background technique [0002] Urban traffic survey and traffic planning need to obtain accurate and reliable travel status data information on a large scale, especially the travel characteristic data of residents. Traditional resident travel surveys often use sampling questionnaires. The sampling rate is generally 2-5% or even lower, and the survey cost is high. Organization and coordination require a lot of manpower, material resources and time, and the cycle of data collection and processing is also long. At this stage, China's urban economy is growing rapidly, infrastructure construction is advancing by leaps and bounds, and land use is more frequent. However, a comprehensive traffic survey is usually conducted every few years. Only relatively static current ...
