deficit zone library district district

Low deficit zone of all branches of public libraries at district level (1,600m and 20 min walking or 8 min cycling). 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.

区级公共图书馆所有分馆的服务盲区（deficit zone）：对应设施的服务覆盖范围为1600米（步行20分钟或骑行8分钟）可达区域的反向区域。服务盲区指处于给定服务范围之外的居住区域。该数据图层每年1月更新，更新前提为相关主管部门或服务机构已对设施完成年度管理与维护。设施的服务范围基于步行距离划定，同时需考量各类重要通行障碍（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等）。邻里区域及邻里配套设施的步行服务范围分别为400米（步行约5分钟）与800米（步行约10分钟）；以区级行政区或邮政编码区为服务单元的设施，其服务范围为1600米（步行20分钟或骑行8分钟）。设施的服务盲区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）。为消除服务盲区，应在该盲区周边增设新的公共服务设施。据此，政策制定者可基于步行距离规划实现公共设施空间布局的均衡化。
