Measuring walkability for distinct pedestrian groups with a participatory assessment method: A case study in Lisbon

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.
