无障碍措施和地图有助于查明获得服务和设施水平较差的社会群体和地点。然而，这些措施不能直接解释不同社会群体在身体能力和活动水平上的差异。此外，对于老年人等被排除在外的人群来说，许多无障碍问题是微观层面的，如人行道上的障碍物，而无障碍措施往往是宏观层面的，不包括整个旅程。为了做到这一点，一个基于gis的工具AMELIA已经被开发出来。本文讨论了AMELIA中纳入的可达性的具体要素，如步行和公共交通可达性的建模，所需的微观层面数据，所考虑的不同社会群体的能力以及这些因素如何影响可达性措施。以英国赫特福德郡圣奥尔本斯为案例研究区域，将为老年人制作的公共交通可达性地图与年轻人制作的公共交通可达性地图进行比较。
Accessibility measures and maps are useful in helping to identify social groups and locations with poor levels of access to services and facilities. These measures however fail to directly account for differences in physical capabilities and mobility levels of different social groups of people. Also, many of the access issues for the excluded groups of people such as the elderly are micro level such as the obstructions in pavements, while accessibility measures tend to be at macro level and do not include the whole journey.To help do this a GIS-based tool, AMELIA, has been developed. This paper discusses the specific elements of accessibility incorporated in AMELIA such as the modelling of walk and public transport accessibility, the micro level data required, the capabilities of the different social groups considered and how these affect the accessibility measures. Public transport accessibility maps produced for the elderly people are compared to those of the younger people using St Albans in Hertfordshire, UK, as a case study area.
