Suburban Sustainability

Sidewalks are a critical part of sustainable transportation systems, supporting pedestrian travel and healthy physical activity. Presence and quality of sidewalks is a significant predictor of perceived safety and quality of the pedestrian environment. Lack of adequate pedestrian infrastructure data has been identified as a major barrier to large-scale pedestrian planning. Sidewalk presence, width, and surface condition are identified as important indicators of facility quality and accessibility. Georgia Tech is deploying an Android tablet application to automatically generate spatial sidewalk inventories, automatically assess sidewalk quality, and prioritize sidewalk repairs. The research team has collected field data on sidewalk segments across …
