The City of Los Angeles, Bureau of Engineering maintains over 11,000 miles of sidewalks. When a segment of sidewalk does not settle evenly or has been raised up by tree-root growth, the sidewalk becomes uneven. This can create pedestrian hazards.  In addition, the City is obligated to ensure that its sidewalks conform to Federal ADA standards, which limit the extent to which a sidewalk may slope.

ABSTRACT / DESCRIPTION: This is the fifth term of a multi-year project. In the last term, a  rover has been successfully fabricated. Now, the rover is capable of 1) moving autonomously, 2) measuring crossing slopes and running slopes, 3) collecting  GPS data, and 4) taking photo images. In this term, we will continue on developing various software that 1) lenders the photo images with slope data and GPS data, (in office) 2) assists field crew while they are collecting data in the field (i.e.user-friendly mobile app/web app). 3) develop a denoising raw data algorithm, 4) develop an algorithm to map field GPS data in Navigate LA GPS data and upload data into the back-end database server together with other denoised raw data, and 5) develop an interface to Navigate LA to visualize raw data on the Navigate LA map layer.
