deficit zone district house district office district

Low with deficit zone of district houses and city offices 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, etc.) 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). In combination with the deficit zone, this layer gives an idea of the spatial distribution of this facility. This allows the policy to plan a balanced spatial distribution of the facility based on walking distance.

本数据集包含区级层面住宅区与市政办公楼的服务赤字区域，相关设施的服务覆盖范围为1600米，即步行20分钟或骑行8分钟可达。所谓服务赤字区域，即与给定服务覆盖范围区域互补的住宅区区域。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运营方每年对设施进行维护与更新。设施的服务范围以步行距离为基准划定，同时需综合考量各类重要通行障碍（如水域、环路、高速公路、铁路等），以及为弱势道路使用者设置的安全过街设施（隧道、桥梁、带交通信号灯的人行横道等）。针对邻里单元及邻里级配套设施，其服务步行距离分别为400米（步行5分钟）与800米（步行10分钟）。区级（行政区或邮政编码区）覆盖的配套设施，服务范围为1600米，对应步行20分钟或骑行8分钟可达。结合服务赤字区域数据，该图层可直观展现该设施的空间分布特征，助力政策制定者基于步行可达性规划设施的均衡空间布局。
