Deficit Zone Service Center District

Low with deficit zone of the service centers 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.区级服务中心存在覆盖缺口区域，其服务范围为步行800米或10分钟可达。覆盖缺口区域指与给定服务覆盖范围互补的居住区域。该数据图层每年1月更新，前提是相关主管部门或业务板块已对设施完成年度管理与更新。设施的服务范围基于步行距离划定，同时需考量重要通行障碍（水域、环路、高速公路、铁路等）以及面向弱势道路使用者的安全过街设施（隧道、桥梁、带交通信号灯的人行横道）。邻里设施与社区设施的步行可达范围分别为400米（5分钟步行）与800米（10分钟步行）。面向区级（行政区或邮区）的设施，其服务范围为1600米（20分钟步行或8分钟骑行）。设施的覆盖缺口区域指处于对应设施服务范围（400米、800米或1600米）之外的居住区域（含规划居住区域）。为消除覆盖缺口，需在缺口区域周边增设新的服务设施。据此，政策可基于步行距离规划设施的空间均衡布局。
