Embodiment Construction

[0030] figure 1 The flow of the method for traffic network analysis in an embodiment is shown, including the following steps:

[0031] In step S10, geographic data, mobile phone base station positioning data, road network data and bus line network data are imported and organized and managed to obtain basic data. The mobile phone base station positioning data is the mobile phone location information obtained in the mobile communication network. The geographic data records the geographic coordinates, which are all original data. The basic data is obtained by organizing and managing the original data. This basic data records the population travel trajectory information. In one embodiment, if figure 2 As shown, the process of step S10 is specifically:

[0032]In step S101, geographic data and mobile phone base station positioning data are acquired, and the mobile phone base station positioning data are preprocessed according to the geographical data. In one embodiment, the pr...

Abstract

The invention relates to a method for analyzing a traffic network, comprising the steps of: importing, organizing and managing geographic data, mobile phone base station positioning data, road network data and public transportation net data to obtain base data; comprehensively processing the base data and establishing a population travel time-space characteristic model to obtain the comprehensive data; and analyzing the traffic management according to the comprehensive data. In combination with the mobile phone base station positioning data, the public transportation network data, the road network data, and the like, the traffic network analysis method ensures that the population travel information dynamic change is obtained, the traffic information based on the population travel characteristic is found, and the service quality reliability is analyzed through a traffic topology network, traffic accessibility and relative analysis. The invention provides convincement and effective decision support for traffic management, traffic plan, land utilization planning, urban planning, and the like, can effectively improve the use ratio of public traffic and a road network, relieves the pressure of the urban traffic, and provides a method for solving the problems in traffic management and traffic planning.

Description

【Technical field】 [0001] The invention relates to modeling technology, in particular to a traffic network analysis method and system. 【Background technique】 [0002] Urban traffic is the "blood" of the city, which continuously transmits the flow of passengers, goods and information in the city to ensure the normal operation of people's daily life. The quality of urban traffic conditions also directly affects the living standards of residents and the future of urban development, so it is necessary to analyze and evaluate the urban traffic conditions. The traditional transportation network analysis uses population censuses and population surveys to obtain population travel data. However, this traditional method of obtaining data has defects such as high data cost, long acquisition cycle, poor data quality, and very high cost. Grasp the dynamic characteristics of population travel information in real time. [0003] How to obtain population travel data through high-tech means ...
