deficit zone supermarket district

Low with deficit zone of supermarkets (>1.000m2) at district level (800m and 10 min walk). The deficit zone is the residential area that represents the inverse of the given range zone. This data layer is updated annually in January, provided that the facility is managed and updated annually by the relevant sector/service. The facility has a certain range based on walking distance, taking into account important barriers (water, ring, highway, rail, ...) and safe crossings for vulnerable road users (tunnels, bridges, pedestrian crossings with traffic lights). A neighborhood and neighborhood facility gets a walking distance of respectively 400 meters and 800 meters (respectively 5 and 10 min walk). Facilities that function on district (district or postcode) have a range of 1600 meters (20 min walking or 8 min cycling). The shortfall zone of the facility represents those residential areas (including the planned residential areas) that are outside the range (400 or 800m and 1600m) of a facility. In order to eliminate the deficit zone, new facilities should be installed in the vicinity of this deficit zone. The policy can thus plan a balanced spatial distribution of facilities based on walking distance.
