The Georgia Department of Transportation and the Southeastern Transportation Research, Innovation, Development, and Education Center at the Georgia Institute of Technology have published a report on automated methods for evaluating sidewalks that includes a tool for assessing their quality and safety. Developed to help communities evaluate sidewalk condition and ADA compatibility, the system consists of an Android application to collect GPS-tagged video of the sidewalks and record Android tablet gyro and accelerometer data for use in evaluating their quality.

By adapting existing vehicle tracking video processing tools, researchers were able to post-process the video to estimate sidewalk width, identify cracks and potholes in need of maintenance, and record the localized presence of walkway obstructions. 

Although the system does not completely automate the video data processing, the system may significantly reduce labor required to assess sidewalk quality and facilitate consistent reviews and state-of-system asset management archives.
