A dedicated pedestrian phase begins with WALK, then a flashing clearance interval and a steady hold interval. Follow the last permitted starter and compare the configured clearance against crossing distance and walking speed.
• 3D scene parts: Marked crosswalk; permitted pedestrian cohort; pedestrian signal heads; clearance countdown; curb waiting areas. • Controls: Curb-to-curb crossing (8–30 m); Selected walking speed (0.5–1.6 m/s); WALK interval (4–15 s); Flashing clearance interval (5–50 s); Steady hold interval (10–40 s). • Live readouts: Required travel time (s); Clearance minus required (s); Last starter distance left (m); Time within cycle (s); Cycle length (s); Last starter completed (0 / 1). • Guided experiments: Slow walker; Provide clearance; Wide crossing. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.

Pedestrian-only timing exercise, not a compliant complete traffic signal plan. No vehicle-release sequence, conflict simulation, startup distribution or accessibility certification. Walking speed is a selected scenario input; local requirements must be assessed separately. Try the preset experiments, then compare the live readouts with the equations.
No. The last permitted starter leaves at the end of WALK.
Yes. Required time is distance divided by speed.
