deficit zone neighbourhood sports site

Low with deficit zone of neighbourhood sports sites at neighbourhood level (400 m and 5 min walking). The deficit zone is the residential area that reflects the opposite of the specific target area. This data layer is updated annually in January, provided that the facility is managed and updated annually by the responsible sector/service. The device has a certain range based on walking distance, taking into account important barriers (water, ring, highway, rail, etc.) and safe crossing points for vulnerable road users (tunnels, bridges, seabs with traffic lights). A neighbourhood and district facility is given a walking distance of 400 metres and 800 m respectively (5 and 10 minutes of walking). Facilities operating on urban areas (district or postal code) have a range of 1600 metres (20 minutes walking or 8 minutes bicycles). The deficit zone of the facility represents those settlements (including planned settlements) that fall outside the range (400 or 800 m and 1 600 m) of a facility. In order to eliminate the deficit zone, new provisions should be planted in the vicinity of this deficit zone. This will allow the policy to plan a balanced spatial distribution of facilities based on walking distance.

针对邻里级（步行400米或5分钟可达）的社区体育场地，其覆盖不足区域与服务盲区（deficit zone）相关数据。服务盲区指与特定服务覆盖目标区域相对的未覆盖居住区域。该数据图层每年1月更新，更新前提为相关负责部门或运营服务主体已按年度完成场地的管理与更新工作。场地的服务覆盖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，原文“seabs”疑似笔误）。邻里级与区级体育场地的步行覆盖范围分别为400米（5分钟步行）与800米（10分钟步行）。服务于城市区域（以区级或邮政编码为区划单位）的场地，其覆盖范围可达1600米（步行20分钟或骑行8分钟）。体育场地的服务盲区即未被该场地400米、800米或1600米覆盖范围覆盖的聚居区（含规划聚居区）。为消除服务盲区，需在该盲区周边规划新建体育设施，此举可助力政策制定者基于步行可达性，实现体育场地空间布局的均衡规划。
