Great Britain Accessibility Indicators 2023 (AI23)

Overview Accessibility indicators measure the ease of reaching valuable destinations (Levinson and Wu 2020). The current dataset, Great Britain Accessibility Indicators 2023 (AI23), provides small-area indicators to key services such as health, education, employment, and urban centres. This dataset is an updated and expanded version of the the Public Transport Accessibility Indicators for Great Britain 2022 (PTAI22) dataset (available at: https://zenodo.org/records/8037156, and described at: https://www.nature.com/articles/s41597-023-02890-w) (J. Rafael Verduzco Torres and McArthur 2024). In particular, the AI23 dataset provides a suite of ready-to-use accessibility indicators by public transport,bicycle, and on foot to employment, general practices (GPs), hospitals, pharmacies, parks and gardens,primary and secondary schools, supermarkets, main urban centres, and urban sub-centres. These indicatorsare available for 42,000 small area units across Great Britain (GB), specifically at the Lower Super OutputArea (LSOA) level in England and Wales, and the Data Zone (DZ) level in Scotland. It includes active modes, specifically walking and cycling, in addition to public transport. A full data descriptor is available here (URL: https://osf.io/preprints/socarxiv/qb9j4_v1) (Verduzco Torres & McArthur, 2024b).

Rafael Verduzco Torres与McArthur，2024）。 具体而言，AI23数据集提供了一套可直接使用的可达性指标，覆盖公共交通、自行车、步行三种出行方式，可用于评估就业、全科诊所（general practices，GPs）、医院、药房、公园绿地、中小学、超市、核心城市中心以及城市副中心的可达性。该数据集覆盖英国全境42000个小区域单元，其中英格兰与威尔士采用下层超级输出区（Lower Super Output Area，LSOA）尺度，苏格兰采用数据区（Data Zone，DZ）尺度。除公共交通外，数据集还纳入了步行与骑行两类主动出行方式。 完整的数据描述文档可于以下链接获取：https://osf.io/preprints/socarxiv/qb9j4_v1（Verduzco Torres与McArthur，2024b）。 ## 数据记录 ### 变量 | 变量 | 描述 | | --- | --- | | geo_code | 起始区域的2011版LSOA/DZ地理编码 | | mode | 指标计算所用出行方式，可选值：'pt'为公共交通，'bicycle'为自行车，'walk'为步行 | | time_of_day | 出发时段，可选值：'am'为早7点，'pm'为晚9点。仅公共交通方式支持该字段 | | access_<服务名称>_15 | 累积可达性：15分钟行程范围内的对应类型服务数量 | | access_<服务名称>_30 | 累积可达性：30分钟行程范围内的对应类型服务数量 | | access_<服务名称>_45 | 累积可达性：45分钟行程范围内的对应类型服务数量 | | access_<服务名称>_60 | 累积可达性：60分钟行程范围内的对应类型服务数量 | | access_<服务名称>_75 | 累积可达性：75分钟行程范围内的对应类型服务数量 | | access_<服务名称>_90 | 累积可达性：90分钟行程范围内的对应类型服务数量 | | access_<服务名称>_105 | 累积可达性：105分钟行程范围内的对应类型服务数量 | | access_<服务名称>_120 | 累积可达性：120分钟行程范围内的对应类型服务数量 | | access_<服务名称>_15_pct | 相对累积可达性：15分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_30_pct | 相对累积可达性：30分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_45_pct | 相对累积可达性：45分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_60_pct | 相对累积可达性：60分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_75_pct | 相对累积可达性：75分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_90_pct | 相对累积可达性：90分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_105_pct | 相对累积可达性：105分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | access_<服务名称>_120_pct | 相对累积可达性：120分钟行程范围内的对应类型服务占比，取值范围为0~100的百分比数值 | | nearest_<服务名称> | 抵达最近的对应类型服务所需的出行时长（单位：分钟） | ## 引用 若您使用本数据集或其部分内容，请采用以下引用格式： 1.
