Problems solved by technology

At present, the population estimation is mostly concentrated on the grid scale. The grid population estimation has the advantages of simple calculation, convenient storage, and strong regularity. However, the grid will cause the division of natural features, and there are large features in the grid. Heterogeneity, there are few population estimates at the building scale, and there is a lack of true description of the spatial distribution of population information

Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0054] In the present invention, IC card mainly refers to the corresponding various IC cards such as bus card, subway card, monthly card, annual card etc. that realizes traffic travel function, and the present invention takes IC card as example, but those skilled in the art know, The present invention is not limited to an IC card, as long as it is a card capable of recording and obtaining traffic travel records.

[0055] The present invention lies in: using the IC card based on the traffic card to obtain the trave...

Abstract

A method for estimating the commuter population of a building based on IC data and a storage medium, the method includes sorting out travel records based on traffic IC card data, identifying occupation and residence and identifying commuters, integrating POI and AOI data, identifying commuters and occupation and residence and other technologies to achieve a smaller-scale description of the spatial distribution of the commuter population. The present invention uses buildings as the basic unit to estimate commuter population distribution, and lays a solid foundation for randomly occurring security incidents, mastering the population distribution of each region, dredging people's flow and other emergency rescue arrangements, and emergency management based on public affairs.

Description

technical field [0001] The present application relates to a method for estimating population, in particular to a method for estimating commuting population of a building based on IC card data and its storage medium. Background technique [0002] The separation of residents and jobs in physical space is the root cause of commuting activities. Therefore, the commuting pattern of urban residents reflects the spatial relationship between jobs and housing to a certain extent and interprets the urban spatial structure. The daily activities of residents are basically based on urban buildings, and the regional distribution of population also occurs in time stages. Compared with other resident activities, commuting activities have greater invariance in time and space. The dynamic grasp of the spatial distribution of urban commuting population is to understand the law of commuting population activities, understand the urban spatial structure, and configure urban infrastructure and pub...
