|Title:||Active accessibility: A review of operational measures of walking and cycling accessibility|
|Abstract:||Active travel is enthusiastically promoted in the Westernworld due to its clear and demonstrated individual and collective benefits. While active travel has been shown to be associated with featuresof the built environment such as density and land-use mix, it is alsoassociated with walking and cycling accessibility-which we designateas active accessibility. However, the measurement of active accessibility is not straightforward and it can represent significantly differentfeatures of the built environment. This paper presents an extensivereview of published research that measures active accessibility. Weclassified the literature into four categories based on the methodologyused: distance-based, gravity-based or potential, topological or infrastructure-based, and walkability and walk score-type measures. A fifthcategory was created to classify outliers consisting of distinct methodological approaches or hybrids of the four main categories. We arguethat almost all of these methods have conceptual and computationallimitations, and that there are inconsistencies in the use of conceptsand terms. Furthermore, no sensitivity analysis was carried out on theselected parameters. We conclude by presenting some guidelines thatmight improve the value and clarity of active accessibility research,theory, and practice.|
