Problems solved by technology

However, the requirements of various applications are very different, and often require different levels of data to meet. For example, the analysis of occupation and residence only needs the location coordinates to be accurate to a small area, while the analysis of road conditions needs to be accurate to a certain road; and the mobile phone signaling data involves personal l

Embodiment Construction

[0027] The specific implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings. Specific steps are as follows:

[0028] Step 1: Sort user U's mobile phone signaling location track data by time, see Table 1;

[0029] Table 1: The results of cell phone signaling location track data sorted by time

[0030]

[0031] Step 2: Discriminate between moving and staying states, according to user u i The relationship between time and space position, calculate the moving speed, when the speed of several consecutive position track points is less than a certain speed threshold, it is considered that the user is in the staying state, otherwise it is in the moving state, for example, calculate u 1 and u 2 The Euclidean distance between:

[0032]

[0033] calculate u 1 The moving speed v 1 = d 1,2 / t 2 -t 1 =1.36 / 10=0.136, the calculation process of other recorded moving speeds is similar to this, and the calcul...

Abstract

The invention discloses a general data set generation method based on mobile phone signalling position trajectory data. The general data set generation method comprises the steps of: sorting originaldata firstly, performing moving and staying state discrimination, compressing staying data, matching affiliated roads, and matching affiliated regions to obtain a general data set. The general data set can support a plurality of traffic applications such as road network operation monitoring, regional passenger flow monitoring, travel path identification, travel characteristic analysis, comprehensive traffic planning and traffic information service, and effectively improves the using convenience of mobile phone signalling data. The general data set generation method belongs to the technical field of transportation.

Description

technical field [0001] The invention belongs to the technical field of transportation and processes mobile phone signaling position track data into a general data set. The data set can be used to analyze user's job, residence and travel rules, and can also analyze road congestion conditions. Background technique [0002] When the mobile phone communicates externally, it will communicate with the nearby base station. The base station will record the serial number, communication time, communication type and base station serial number of the communicating mobile phone and send it back to the background data management center. Through long-term data accumulation, the continuous location track of the mobile phone can be recorded , known as mobile phone signaling position track data (hereinafter referred to as "mobile phone signaling data"), it has the following advantages: [0003] (1) A huge sample size, the basic data comes from mobile phone users, and has a very high usage rat...
