Real-World Stairways: Need for Visual Contrast Enhancements to Mitigate the Hazards of Variable Step Geometry

Abstract

Variation in step dimensions in a stairway can decrease step predictability and increase users’ fall risk. We discuss past stairway dimension irregularities, current stairway design codes, and how visual contrast enhancements may improve stairway safety by drawing stair users’ attention to the steps.

Keywords
