Pedestrian Network

A Pedestrian Network is the connected graph of walkable routes including sidewalks, crosswalks, trails, pedestrian bridges, and shared-use paths that facilitates movement on foot within urban and suburban environments. Unlike vehicular networks that are well-mapped and routinely analyzed, pedestrian networks have historically received less attention in geospatial databases, creating gaps in routing and accessibility analysisAccessibility AnalysisAccessibility Analysis measures how easily people can reach destinations such as jobs, services, healthcare, and amen.... Analysis methods include connectivity assessment, which measures how directly pedestrians can travel between origins and destinations compared to vehicular routes. Impedance modeling accounts for factors that discourage walking such as steep grades, missing sidewalks, wide road crossings, and lack of shade. ADA compliance auditing uses GISGISGeographic Information Systems (GIS) enable users to analyze and visualize spatial data to uncover patterns, relation... to identify barriers like missing curb ramps, obstructed sidewalks, and inaccessible crossings that prevent mobility-impaired individuals from navigating the network. Applications include Safe Routes to School programs that map and improve walking paths for students, age-friendly city initiatives that ensure seniors can navigate neighborhoods safely, and transit access studies that evaluate pedestrian connections to bus stops and train stations.
