Method and device for determining urban core area

Abstract

The invention relates to a method for determining an urban core area. The method comprises the following steps: establishing a grid buffer area based on position service request data; establishing a flow buffer area based on the urban road traffic flow; and combining the grid buffer area and the flow buffer area to form an urban core area. The method can overcome the difficulty that the urban corearea cannot be effectively divided and dynamically updated at present based on dynamic and static traffic data of vehicle-mounted navigation and electronic map manufacturers. Dynamic determination ofan urban core area is realized from two dimensions of urban positioning request heating power and a vehicle passing area through an internet technology and by applying a traffic big data analysis means. By establishing a unified determination standard, effective data support is provided for expansion and development trends of different cities in different periods, and a data foundation is laid for city development planning, traffic state evaluation and comprehensive prediction analysis.

Description

Technical field [0001] The invention relates to the fields of intelligent transportation, electronic maps, car navigation, urban planning and the like, and in particular to a determining method and device suitable for determining the core area of ​​a city. Background technique [0002] Administrative division is the abbreviation of administrative division, which is the division of regions implemented by the state for hierarchical management; the state is divided into administrative districts by region, and the administrative divisions of various countries have different divisions and names. Built-up area refers to the non-agricultural production and construction area developed through expropriated land and actual construction within the municipal administrative area. It includes the concentrated and contiguous parts of the urban area and the scattered in the suburbs. It is closely related to the city and has basically complete municipal utilities. Urban construction land for faci...

Problems solved by technology

The determination and evolution of urban core areas can lay a data foundation for urban development planning, traffic status evaluation, and comprehensive forecast analysis. China's statistics department uses built-up areas to reflect the size of a city's urbanization area, but except for individual local standards, there are no such data throughout the country. There is no uniform definition of standards and operating procedures, and the method for determining the core area is even blank
