陕西省西安市停车情况综合分析数据

提供陕西省西安市道路停车数据，方便交通管理部门及停车运营单位查询陕西省西安市内的停车情况，分析道路停车的各路段泊位周转率、日平均停车时长分布等，进行停车运营的管理。当车辆驶入或驶出停车位时，安装在此停车位上的地磁车位检测器检测到磁场变化，判断有车还是无车，将判断后的数据通过NB-IoT实时传输到云平台， 平台解析数据并根据数据库中存储的车位设备关系表，找到对应所属的车位编号以及路段信息。平台每小时按照省份、城市、路段的层次从数据库检索，并按照如下规则做数据统计：统计最近一小时内，该路段下所有泊位地磁上报的有车总数据条数作为【停车次数】；统计当前时刻该路段下有车的泊位数量，作为【占用泊位】数量；统计当前时刻该路段下无车的泊位数量，作为【空闲泊位】数量；空闲泊位+占用泊位作为【泊位总数】；占用泊位/泊位总数作为【泊位占用率】；停车次数/泊位总数作为【周转率】；每个泊位停车时长总和作为【总停车时长】；总停车时长/停车次数 作为【平均停车时长】； 最后将省份、城市、路段、日期、统计时间、泊位总数、空闲泊位、占用泊位、泊位占用率、停车次数、周转率、总停车时长(分钟)、平均停车时长（分钟）存储到数据库中供后续查询。

This dataset provides road parking data for Xi'an City, Shaanxi Province, to enable traffic management authorities and parking operation enterprises to query parking status within Xi'an, analyze indicators including the turnover rate of parking spaces in each road segment and the distribution of daily average parking duration, and support parking operation management. When a vehicle enters or exits a parking space, the geomagnetic parking space detector installed on the corresponding parking spot detects magnetic field changes to determine whether the space is occupied or vacant, and transmits the determined data to the cloud platform in real time via NB-IoT. The cloud platform parses the received data, and matches the corresponding parking space number and road segment information based on the parking space-device relationship table stored in the database. On an hourly basis, the platform retrieves data from the database at the hierarchical levels of province, city and road segment, and conducts data statistics according to the following rules: 1. Count the total number of occupied status reports submitted by all geomagnetic detectors of parking spaces under this road segment within the last hour as [Parking Times]; 2. Count the number of occupied parking spaces under this road segment at the current moment as [Occupied Parking Spaces]; 3. Count the number of vacant parking spaces under this road segment at the current moment as [Vacant Parking Spaces]; 4. The sum of Vacant Parking Spaces and Occupied Parking Spaces is defined as [Total Number of Parking Spaces]; 5. The ratio of Occupied Parking Spaces to Total Number of Parking Spaces is defined as [Parking Space Occupancy Rate]; 6. The ratio of Parking Times to Total Number of Parking Spaces is defined as [Turnover Rate]; 7. The total parking duration across all parking spaces under this road segment is defined as [Total Parking Duration]; 8. The ratio of Total Parking Duration to Parking Times is defined as [Average Parking Duration]. Finally, the platform stores the following data into the database for subsequent query: province, city, road segment, date, statistical timestamp, total number of parking spaces, vacant parking spaces, occupied parking spaces, parking space occupancy rate, parking times, turnover rate, total parking duration (in minutes), and average parking duration (in minutes).
