Average time to 8 key services by PT/walk - WMCA

This is the average travel time in minutes to 8 key services by public transport/walking. The 8 key services are the average of minimum journey times to medium sized centres of employment (500-4999 jobs), primary schools, secondary schools, further education, GPs, hospitals, food stores and town centres.It is part of the Journey Time Statistics produced by DfT which consists of theoretical journey times calculated by modelling journeys between known sets of origins and destinations, using information on the road network, traffic speeds and public transport timetables.Statistics are designed to represent as far as possible the situation in October of the year to which they related. The origins, destinations and public transport timetables used are as far as possible for this date. The traffic data are averages for the preceding 12 months up to and including August. The road networks are those for the previous spring.The origins used for all Access to Services calculations are the English Output Areas (OA). To provide the actual journey start point in each OA, the population weighted centroid of the OA was shifted to the nearest node (i.e junction) on the road network.These statistics are very similar to those of the Accessibility Statistics, however, the methodology employed is different so the results are not directly comparable."Data is Powered by LG Inform Plus and automatically checked for new data on the 3rd of each month.

本数据集展示了通过公共交通/步行前往8项关键服务设施的平均旅行时间（单位：分钟）。这8项关键服务设施包括：平均到达中型就业中心（就业岗位500-4999人）、小学、中学、继续教育机构、全科医生、医院、食品商店和城镇中心的最低行程时间。该数据集是英国交通部（DfT）发布的行程时间统计数据的一部分，这些统计数据通过模拟已知起点和终点之间的行程，利用道路网络、交通速度和公共交通时刻表信息进行计算而得出。统计数据旨在尽可能地反映与所涉年份10月相符的情况。所使用的起点、终点和公共交通时刻表尽可能与该日期相符。交通数据为前12个月（包括8月）的平均值。道路网络为前一年的春季数据。所有服务可达性计算所使用的起点均为英格兰输出区域（OA）。为了提供每个OA的实际行程起点，OA的人口加权质心被移动到最近的节点（即交叉口）上。这些统计数据与可达性统计数据非常相似，然而，所采用的方法不同，因此结果不可直接比较。数据由LG Inform Plus提供支持，并于每月的3日自动检查新数据。
