Description
Summary:We conduct a systematic scoping review of the academic literature concerning pedestrian accessibility. We distinguish "walking accessibility" from the broader topic of "walkability" by two criteria: papers must consider one or more destination type(s), and papers must address the issue of distance or impedance. After searching Web of Science, TRID, and Google Scholar databases and conducting screening, we identify 85 papers meeting these criteria. We organise the literature review according to the four components of accessibility identified by Geurs and van Wee [(2004). Accessibility evaluation of land-use and transport strategies: Review and research directions. Journal of Transport Geography, 12(2), 127-140]: (1) Land use; (2) transport; (3) temporal; and (4) individual and also add a section on the topic of impedance. Walking accessibility studies address a much greater range of land uses or destination types than is typically found for other modes. The transportation component is relatively undeveloped, as pedestrian infrastructure includes many influential elements not currently tracked in GIS systems. Few studies address the temporal component of walk accessibility, which varies according to climatic and nighttime conditions. Most papers do not account for the significant variation across individual capabilities and preferences regarding walking. We note that developing detailed pedestrian networks is a key first step, as most published analysis is conducted on roadway networks. A second major recommendation is to consider individual variations in walk accessibility across demographic classifications, accounting for varying levels of physical mobility.
