ADA Accessibility Path Analysis
AI analysis of accessible routes and paths of travel for ADA compliance in buildings.
Definition
ADA Accessibility Path Analysis uses AI and computer vision to trace and verify accessible routes throughout buildings. It identifies barriers, measures slopes and cross-slopes, checks door clearances, and ensures continuous accessible paths from site arrival to all building areas as required by the Americans with Disabilities Act.
In Depth
Accessible route analysis is one of the most geometry-intensive code compliance tasks in building design. Every building must provide at least one accessible route from the public way to every accessible space, and that route must comply with dozens of specific dimensional requirements — minimum widths, maximum slopes, door maneuvering clearances, turning spaces, and surface conditions.
AI traces accessible routes on floor plans the way a plan examiner would, starting at the site entrance and following the path through the lobby, corridors, elevators, and into each occupied space. At every point along the route, the AI checks the applicable dimensional requirements: 44-inch minimum corridor width (or 36 inches for short distances), 1:20 maximum running slope, 1:48 maximum cross-slope, turning radius at direction changes, and proper clearances at every door.
The path analysis is especially valuable for renovation projects where existing conditions constrain the design. AI can identify which portions of an accessible route comply, which portions need modification, and what the minimum modifications would be to achieve compliance. For historic buildings where strict compliance may not be feasible, the AI can document the existing conditions to support an application for an alternative compliance path under the ADA.
