Embodiment Construction

[0032] The concrete implementation process of the present invention is as figure 1 As shown, each step can be realized by processing data through computer programming. The program running hardware environment is Hewlett-Packard xw8600WorkStation, the operating system is Microsoft Windows XP Professional x64 Edition2003 SP2, and it is developed with Microsoft Visual Studio 2005.

[0033] The specific execution steps are as follows:

[0034] Step 1: Loading and matching of traffic area information and base station information

[0035] figure 2 It is a partial screenshot of the read traffic area and base station data displayed on the map. The polygonal area in the figure is the traffic area, and the number in the middle of the area is the traffic area number. The small black circles in the figure are base stations, and each base station has a corresponding actual number.

[0036] According to the positional relationship between the base station and the traffic area, each bas...

Abstract

The invention relates to a method for computing traffic trips by using mobile phone information. The method computes the information of trips among zones by analyzing and processing the mobile phone information and combining the traffic zone division, thereby providing reference for traffic planning and management. The concrete technical scheme of the invention comprises the following steps: firstly, reading traffic zone information and base station information from a database, and establishing a membership relative to each other according to the respective geographic positions; classifying the position points of mobile phone records according to users, and carrying out data processing of filtering improper users, filtering useless information and the like; and judging the lingering points of the users through the time difference of the uploaded information and event types, and further computing the trips among the traffic zones and the attraction amount generated in the traffic of each zone through pairwise continuous lingering points. The method does not need a door-to-door manual survey and post statistical processing of data, thereby saving a large amount of manpower and material resources.

Description

technical field [0001] The invention belongs to the field of traffic information collection and processing in traffic planning and management, and relates to a method for calculating the amount of travel and the amount of generation and attraction between traffic cells at the origin and destination by using mobile phone information. Background technique [0002] Traffic survey and travel analysis are the basis for traffic planning and traffic management policy formulation. At present, the travel survey of residents is mainly carried out through manual household survey, the sampling rate is low, and the collection and analysis process is long. With the rapid development of urban traffic construction, the change of traffic demand is accelerating, and the requirements for traffic survey and analysis work are constantly increasing. The traditional traffic demand analysis methods can no longer meet the current needs. The traffic demand analysis and planning decision support syst...
