Urban area division method and device

Abstract

The invention provides an urban area division method and device, and the method comprises the steps: firstly, collecting the multi-dimensional data in an urban area, extracting the character trajectory data from the character behavior data in the multi-dimensional data, and then generating first trajectory information; Determining a regional vehicle life and work index according to the vehicle track data, determining density values of various interest points according to the interest point data, determining a regional power consumption evaluation index according to the power consumption data,and fusing the determined data into a corresponding track point in the first track information to obtain second track information; Performing clustering processing on the second track information, andidentifying a class label of the track of the second track information according to a clustering result; And finally, dividing an urban area according to the category label of the track. According tothe invention, the regional characteristics can be effectively extracted from the multi-dimensional data in the city region, and the city region is divided through the regional characteristics, so that the accuracy of city region division is improved.

Description

technical field [0001] The invention relates to the technical field of urban functional area division, in particular to a method and device for urban area division. Background technique [0002] Urban planning and management often have their own planning during urban construction and renovation. However, with the continuous development of the city, the layout and functions of the city are also changing. How to evaluate and classify the various areas of the city can be used for Provide support for urban management and reconstruction; the most common method of dividing urban areas is to use POI (Point of Interest) to divide urban areas functionally. The performance may be very different, and it is difficult to distinguish between simple divisions. At the same time, it is very difficult to define some POI complex areas. In the prior art, it is also proposed to use data such as bus routes, human behavior, and vehicle trajectories to define urban functional areas. However, it is...

[0002] Urban planning and management often have their own planning during urban construction and renovation. However, with the continuous development of the city, the layout and functions of the city are also changing. How to evaluate and classify the various areas of the city can be used for Provide support for urban management and reconstruction; the most common method of dividing urban areas is to use POI (Point of Interest) to divide urban areas functionally. The performance may be very different, and it is difficult to distinguish between simple divisions. At the same time, it is very difficult to define some POI complex areas. In the prior art, it is also proposed to use data such as bus routes, human behavior, and vehicle trajectories to define urban functional areas. division, but this method is difficult to effectively extract regional features from trajectory data, so that the accuracy of urban division is poor
