Abstract
Proximity-oriented planning aims to promote active transportation and reduce car dependence by ensuring essential services are within a short walking or cycling distance. While often seen as promoting social interactions, models like the “15-minute city” risk reinforcing spatial segregation by limiting interactions among diverse demographic groups. Addressing the lack of tools to analyze these effects, CTwalk is a data-driven software tool that maps the encounter potential of urban destinations across population groups within 5- and 15-minute walks. The tool identifies access inequities and evaluates how different destinations are mutually accessible to diverse populations.
