WebApr 30, 2024 · Stopping Sight Distance. Stopping Sight Distance (SSD) is the viewable distance required for a driver to see so that he or she can make a complete stop in the event of an unforeseen hazard. SSD is made up of two components: (1) Braking Distance and (2) Perception-Reaction Time. Forces acting on a vehicle that is braking. WebThe stopping distance depends on factors including road surface, and reflexes of the car’s driver and it is denoted by d. Stopping Distance formula is given by, Where, d = stopping distance (m) v = velocity (m/s) μ = friction coefficient g = acceleration due to gravity (9.8 ) The stopping distance formula is also given by, Where, WebAug 1, 2024 · Our stopping distance calculator allows you to input any perception-reaction times.
