TrailGrade

Check hiking trail gradients against accessibility standard requirements

Environmental AIFree

TrailGrade evaluates hiking trail profile data against US Forest Service Trail Accessibility Guidelines and Architectural Barriers Act standards for outdoor developed areas. The tool identifies segments exceeding maximum running slope, cross slope, and obstacle height thresholds and calculates resting interval requirements from sustained grade lengths. Trail difficulty classification using Shenandoah and modified Yosemite decimal systems helps land managers match trail marketing to actual physical demands.
