Developing enriched pedestrian networks using accessibility features

Abstract. Accessibility studies often focus on the general population, overlooking individual differences in mobility capacities and the role of external factors. Microscale street elements such as stairs, high kerbs, and sidewalk cracks can significantly impact urban mobility for individuals with restricted movement capacities. This study introduces a workflow to integrate different detailed accessibility information, such as barriers and facilitators for pedestrian mobility, with sidewalk data to create an enriched pedestrian network. Using this network, we evaluate each segment by computing an impedance score to quantify accessibility. Furthermore, we demonstrate how the network can be tailored to individual mobility needs and highlight its potential as a decision-making tool for urban planners and civil engineers to identify and prioritise targeted interventions for vulnerable populations.
