deficit zone youth centre youth house district

Low with deficit zone of the urban youth centers and youth houses 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.本数据集涵盖区级城市青年中心与青年之家的服务覆盖赤字区域（deficit zone），该类设施的服务半径为1600米，对应步行20分钟或骑行8分钟。服务覆盖赤字区域指的是落在指定服务范围之外的居住区。本数据图层每年1月更新，前提是相关主管部门或服务运营方每年对设施进行运维与更新。各类设施以步行距离为基准划定服务范围，同时需考量各类重要通行障碍（河道、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）。街区级设施及街区配套设施的服务步行半径分别为400米与800米，对应步行5分钟与10分钟。以区级（行政区或邮政编码区）为服务范围的设施，其服务半径为1600米（步行20分钟或骑行8分钟）。设施的服务缺口区域指的是未被该设施服务范围（400米、800米或1600米）覆盖的居住区（含规划居住区）。为消除服务覆盖赤字区域，需在该区域周边增设新的配套设施，相关政策可据此以步行距离为基准，统筹规划设施的空间均衡布局。
