摘要

Walkability has been defined as the extent to which the urban environment is pedestrian friendly. By measuring it, planning professionals may be able to address the quality of the pedestrian environment, supporting more objective, effective and comprehensive walking-related strategies and interventions. This work presents a participatory framework for the assessment of walkability based on local circumstances and expertise, replicable on distinct urban contexts. The framework takes into account distinct pedestrian groups (adults, children, seniors and impaired mobility pedestrians) and trip purposes (utilitarian, leisure), expressing walkability in terms of seven key dimensions (7C's layout). From this conceptual framework, a methodology to evaluate walkability through GIS-based and street auditing indicators is presented. It was applied to an area in central Lisbon, Portugal, in order to evaluate the ease or difficulty that different types of pedestrians can face in their walking activities and, potentially, providing an insight for intervention and improvements. The results show clear differences in walkability scores for different pedestrian groups, namely between adults and seniors or impaired pedestrians. Besides, a validation of the results is presented by comparing street performance, as measured by our process, with home-based surveys conducted within the study area. Validation results confirm that the evaluation framework proposed is reliable in the representation of the pedestrian environment qualities as perceived by the public. (C) 2016 Elsevier B.V.
