Abstract
Modern geographic information systems (GIS) and planning support systems (PSS) incorporate numerous pedestrian accessibility and walkability indicators. However, these tools often prioritize spatial metrics over perceptual factors and overlook population-specific differences. This creates a gap between measurable indicators and those valued by planning practitioners. Through co-design workshops, Q methodology, and factor analysis, we identify key factors influencing pedestrian accessibility for diverse populations and highlight areas of alignment and mismatch with existing GIS/PSS indicators.
