High-resolution traffic flow data in Glasgow
收藏资源简介:
Description of the dataset This dataset offers a long-term traffic flow data at an intra-city scale with high spatio-temporal granularity. The dataset covers the Glasgow City Council area for four consecutive years spanning the COVID-19 pandemic, from October 2019 to September 2023, providing comprehensive temporal and spatial coverage. The code used to produce the indicators is available at: https://github.com/YueLi-0816/TrafficFlowData. This work is funded by the China Scholarship Council (CSC) from the Ministry of Education of P.R. China, the ESRC’s ongoing support for the Urban Big Data Centre (UBDC), and the Royal Society International Exchange Scheme. Contents Sensor status metadata - status.csv Column name Description id Unique ID for each sensor, e.g., GA0601_T. latitude The Latitude in decimal degrees of WGS84 coordinates, e.g., 55.86238129. longitude The Longitude in decimal degrees of WGS84 coordinates, e.g., -4.26570708. step 1 The status of sensors at the current step is 1 if retained and 0 if removed. step 2 The status of sensors at the current step is 1 if retained and 0 if removed. step 3 The status of sensors at the current step is 1 if retained and 0 if removed. step 4 The status of sensors at the current step is 1 if retained and 0 if removed. step 5.1 The status of sensors at the current step is 1 if retained and 0 if removed. step 5.2 The status of sensors at the current step is 1 if retained and 0 if removed. Sensor location metadata - locations.csv Column name Description id Unique ID for each sensor, e.g., GA0601_T. latitude The Latitude in decimal degrees of WGS84 coordinates, e.g., 55.86238129. longitude The Longitude in decimal degrees of WGS84 coordinates, e.g., -4.26570708. Traffic flows metadata File name Description [sensor_id].csv Traffic flows. [sensor_id] refers to the ‘id’ from the locations.csv Column name Description date The date the data is collected (YYYY-MM-DD), e.g., 2021-11-04. time The hours of the day the data is collected range from 0 to 23, 0 = [0,1), 23 = [23,24). flow Number of vehicles that pass the sensor location during the one-hour interval.
数据集说明 本数据集提供具有高时空粒度的城市级长期交通流数据。数据集覆盖格拉斯哥市议会管辖范围,时间跨度为2019年10月至2023年9月,完整覆盖新冠疫情期间的连续四年,时空覆盖范围全面完整。 用于生成该数据集指标的代码可通过以下链接获取:https://github.com/YueLi-0816/TrafficFlowData。 本研究得到中华人民共和国教育部下属中国留学基金委(China Scholarship Council, CSC)、英国经济和社会研究理事会(Economic and Social Research Council, ESRC)对城市大数据中心(Urban Big Data Centre, UBDC)的持续资助,以及皇家学会国际交流计划(Royal Society International Exchange Scheme)的支持。 ## 数据集内容 ### 传感器状态元数据 —— status.csv 各字段说明如下: - id:每个传感器的唯一标识符,示例为GA0601_T。 - latitude:WGS84坐标系(World Geodetic System 1984)下的十进制纬度,示例为55.86238129。 - longitude:WGS84坐标系(World Geodetic System 1984)下的十进制经度,示例为-4.26570708。 - step 1:当前步骤下传感器状态为1时代表保留,为0时代表移除。 - step 2:当前步骤下传感器状态为1时代表保留,为0时代表移除。 - step 3:当前步骤下传感器状态为1时代表保留,为0时代表移除。 - step 4:当前步骤下传感器状态为1时代表保留,为0时代表移除。 - step 5.1:当前步骤下传感器状态为1时代表保留,为0时代表移除。 - step 5.2:当前步骤下传感器状态为1时代表保留,为0时代表移除。 ### 传感器位置元数据 —— locations.csv 各字段说明如下: - id:每个传感器的唯一标识符,示例为GA0601_T。 - latitude:WGS84坐标系(World Geodetic System 1984)下的十进制纬度,示例为55.86238129。 - longitude:WGS84坐标系(World Geodetic System 1984)下的十进制经度,示例为-4.26570708。 ### 交通流量元数据 #### 文件名说明 [sensor_id].csv:交通流量数据,其中sensor_id对应locations.csv中的id字段。 #### 字段说明 - date:数据采集日期,格式为YYYY-MM-DD,示例为2021-11-04。 - time:数据采集的当日小时区间,取值范围为0至23,其中0代表[0,1)时段,23代表[23,24)时段。 - flow:一小时时段内经过该传感器点位的车辆总数。
