Pedestrian Crossing

A designated location on a road where pedestrians have legal priority, guidance, or protection to cross, typically marked by paint (zebra or ladder stripes), signs, or signal-controlled infrastructure. Pedestrian crossings range from unmarked mid-block crossings through unsignalized zebra crossings to fully signalized intersections with Accessible Pedestrian Signals (APS), tactile paving, raised curbs, and countdown timers. For accessibility, crossing design is a critical battleground: curb ramps and detectable warning surfaces aid wheelchair users and blind pedestrians; APS with audible and vibrotactile cues support people with vision, hearing, or cognitive differences; and emerging AV-pedestrian communication (external HMIs) must extend these multimodal principles into scenarios without conventional traffic control.
