Abstract

The invention discloses a standard grid division method and device based on road circulation capacity. The method comprises the following steps: dividing to obtain a plurality of basic grids corresponding to road network information; calculating flow capacity values of road sections forming boundaries of the plurality of basic grids; and merging the plurality of basic grids according to the flow capacity value and a grid information threshold of a standard grid, and obtaining the standard grid according to a merging result. According to the scheme, the basic grids are merged according to the flow capacity value of the road section and the grid information threshold value of the standard grid to obtain the standard grid, so that the obtained standard grid meets the actual geographical segmentation significance while meeting the grid information threshold value limitation; moreover, the division scheme is small in calculation amount and high in division efficiency, and standard grids canbe quickly obtained.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for standard grid division based on road circulation capacity. Background technique [0002] Geographical segregation is an important factor affecting the range of activities of people. Based on this, services can be provided based on geographical segregation. It can be seen that the division of geographical segregation is an important prerequisite for providing good services. In practice, it is more common to divide geographical divisions by geographical features such as roads, water systems and / or green spaces. In the Chinese patent application with the application publication number CN109669999A, it is disclosed that the initial map is divided into a plurality of initial grids with the road as the dividing line to obtain a grid map; in the grid map, the designated grid adjacent to the initial grid is searched. Geographic features, wherein the specified g...
