Access to Services - Financial Services
收藏资源简介:
This analysis of access to services was developed for the report, Availability of Rural Services, published by the Scottish Executive in October 2002. Point location data for services was obtained from various public and commercial sources. Where postcode of the service was available, this was georeferenced using the National Records of Scotland's 2002 Postcode Index File (PIF) (and earlier years where required). The drive times catchments were calculated based on the service as the starting point and the properties of the local road network. Each of the road classes within the road network is automatically assigned a speed, considered to be the average for that class of road during off-peak conditions. No modelling was undertaken to take account of variations in speed or delay at junctions during rush hour peak periods. However they do take account of the lower average speeds encountered in built up areas. The drive time software utilised for this analysis was MapInfo Drivetime V6 using Streetline Routing Data from MapInfo. The Postcode Index File 2002 was used to calculate the number of households within each of the drive time catchments. For more information, see http://www.scotland.gov.uk/library5/rural/asrs-25.asp
本项服务可及性分析系为2002年10月苏格兰行政院发布的研究报告《农村服务可及性》(Availability of Rural Services)所编制。本研究所需的服务点位数据取自各类公共与商业数据源。若服务点位的邮编信息可获取,则采用苏格兰国家档案馆2002年邮编索引文件(Postcode Index File,PIF)完成地理配准(按需可使用早年版本文件)。出行时间服务区以服务点位为起点,结合本地道路网络的属性计算得到。道路网络中的每一类道路等级均自动分配对应行驶速度,该速度为非高峰时段该类别道路的平均通行速度。本次分析未针对高峰时段交叉口的车速变化或延误情况构建模型,但已纳入建成区平均车速较低的影响因素。本分析采用的出行时间计算软件为MapInfo Drivetime V6,其使用了MapInfo提供的Streetline路径规划数据。本次研究通过2002年邮编索引文件,计算得到各出行时间服务区内的家庭总户数。更多相关信息可参阅:http://www.scotland.gov.uk/library5/rural/asrs-25.asp
