Access, Aging, and Impairments Part A: Impairments and Behaviorial Responses

As the preceding examples illustrate, accessibility issues (and, in some cases, accessibility conflicts) arise at all levels within the transport planning process. This two-part special issue contains a total of eight papers and one letter addressing this topic. Part A focuses on the problems created by mobility impairments and on behavioral adaptations to overcome these problems. Part B will focus on the ways transport planning on the local and national levels can support access for all. In this context, it is important to distinguish two concepts of accessibility, namely “access to infrastructure” and “access to destinations”; the former is concerned with the barriers that prevent people from using transportation systems, while the latter appears mainly in the land-use literature and refers to regional accessibility patterns.
