Embodiment Construction

[0036] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0037] The technical solution proposed by the present invention is mainly based on the fact that the base station connected to the personal mobile phone will perform position switching, thereby forming a personal trajectory. If the base stations are regarded as points, and the position switching of mobile phones between base stations is regarded as the connection between points, then a network will be formed. For this network, after making statistics within a certain period of time, the analysis of network nodes can objectively reflect the characteristics of people's travel in certain places in the city. Complex network theory is very important for the study of large-scale nodes and complex connections between nodes, and mobile phone signaling data generally has a large amount of data, so based on complex network theory, the scientific nature of th...

Abstract

The present invention discloses a complex network and mobile phone signaling data-based urban transportation junction point evaluation method. According to the method, firstly, a base station of a mobile phone in a to-be-researched area is preprocessed. Secondly, based on the location switching features of the base station, the trajectory of each mobile phone in the to-be-researched area is obtained. Thirdly, according to the trajectory of the mobile phone, the relationship network between base stations is determined. That means, the contact strength between base stations can be reflected through the switching of the mobile phones of people in the base stations, so that the operating characteristics of people in the space can be further embodied. Finally, based on a complex network theory, base stations for representing urban transportation junctions can be determined. According to the technical scheme of the invention, a basis is provided for the position determination of urban transportation junction points and the making of associated traffic decisions based on the switching contact features of mobile phone base stations and the complex network theory.

Description

technical field [0001] The invention relates to the fields of urban planning and urban traffic, in particular to an evaluation method for urban traffic hubs based on complex networks and signaling data of mobile phones. Background technique [0002] There is no doubt that urban transportation hubs are of great significance to urban planning and traffic management. Although transportation hubs often appear as intersections of roads in cities, they are easy to be found and evaluated on the spot. However, it is often difficult to objectively reflect the characteristics of people's activities on urban transportation hubs, especially to evaluate the hierarchical system of transportation hubs based on people's travel characteristics. In recent years, mobile phone signaling big data has been widely used in urban planning, traffic management, social governance, etc., and has achieved remarkable results. These applications are mainly based on the large population coverage of mobile...
