Inventory of Pedestrian Features

SSA uses a Sidewalk Profiler to inventory ADA barriers within sidewalk infrastructure. A profiler uses high resolution lasers, an accelerometer, an optical distance encoder, GPS and tilt sensors to capture highly accurate field measurements. This technology provides for the continuous gathering of large amounts of data, while automatically identifying ADA code violations with their precise GIS location. Our clients meet their legal obligations cost-effectively.

SSA works with clients to implement ADA access improvements using Geographic Information Systems (GIS) and surface profiling technology to capture data, revise compliance status when work is completed, and to help prioritize future projects. SSA uses surface profiling technology to inventory pedestrian features within the rights-of-way. The data captured can be continually updated with a priority ranking system allowing the most severe hazards to be addressed first. Project oversight is improved with a tailored work schedule and instant reports.

Data Collection: Pedestrian Elements

SSA has developed an excellent computer-based tool, which provides a variety of accessibility functions, for its inventory of curb ramps and pedestrian signals. SSA’s electronic Database is a relational database management program that assembles, organizes and maintains field survey data; maintains records of as-built conditions (actual measurements), code requirements (required
measurements), construction cost estimates, and recommendations for solutions for the removal of non-compliant access barriers. The program will also generate the Accessibility Compliance Assessment reports (i.e., the survey report).

The SSA electronic Database will list the identified barriers in a report format that cites all deviations from applicable accessibility requirements contained in the Americans with Disabilities Act Accessibility Standards, and the California State Building Code. The format allows sorting of recorded information by location, type, severity, category, item, cost of identified barriers, etc. All data is exportable and compatible with a variety of formats including Sequel Server (SQL), Microsoft Excel (*.xls) and Adobe Acrobat (*.pdf).
