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...

The invention discloses a personnel travel parameter statistical method based on mobile phone signal data, which comprises main steps of: establishing a virtual sensor network, and acquiring real-time signal data sent by all mobile phones within a time interval from a mobile phone network at fixed time intervals; acquiring electronic footprints of a user according to electronic map information and the real-time signal data; judging whether the user travels or whether secondary travel exists according to the electronic footprints; calculating a travel distance according to road network matching; and finally acquiring a travel OD matrix of an entire statistical area and related travel parameters. The personnel travel parameter statistical method based on the mobile phone signal data fully relies on the existing mobile communication network resources, utilizes information in the existing mobile phone communication network, can complete large-scale traffic travel feature investigation in a city within short time period, and is relatively small in initial investment, large in data coverage area and high in data accuracy.
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 ...
