(2) The fifteen-minute life circle is a daily life range of residents, and is not suitable for crossing major traffic roads or rivers and other obvious barriers. (3) The fifteen minute life circle generally corresponds to the scale of the community and can be defined in combination with the community boundary. Based on the living circle range requirement, the embodiment utilizes the pre-acquired obstacle position data in the region to be segmented to segment the region to be segmented, and a plurality of segments are obtained. Specifically, intersecting the boundary of the region to be delineated with the obstacle position data, several divided regions are obtained as shown in fig. 2. For the region which does not meet the requirement of the life circle range after the primary segmentation, the region needs to be segmented again by using an editing tool of the ArcGIS so as to meet the requirement of the life circle range.
As an alternative embodiment, the ArcGIS is used to identify the center point of each divided area, specifically: and respectively creating an 'x' field and a 'y' field for each segmented region, respectively selecting the attribute of the 'x' field and the 'y' field as the 'x coordinate of the centroid' and the 'y coordinate of the centroid', and performing calculation geometric processing to obtain the central point of each segmented region.

and extending the preset travel distance along the direction away from the central point based on the central point of each divided area, and acquiring the travel range corresponding to each divided area.
In the embodiment, 15-minute travel ranges of the center points are calculated based on the center point of each divided area in consideration of the requirement that the community life circle needs to meet 15-minute accessibility. Specifically, by using the network analysis function of ArcGIS, the impedance in the network analysis parameters is set to be "length (meter)", the default interruption is set to be "preset travel distance", the direction is set to be "direction away from the center point", and the center point of each divided area is subjected to network analysis, so as to obtain the travel range corresponding to each divided area.
