Define stopping sight distance
WebFeb 19, 2014 · As per IRC (Indian Roads Congress), Stopping sight distance is such a distance, along the centreline of the road, that any obstruction of 0.15 m, at the other end, must become visible to the eye of a driver at a height of 1.2 m from the road surface. WebApr 30, 2024 · Stopping Sight Distance Sight distance is dependent on the type of curve used and the design speed. For crest curves, sight distance is limited by the curve itself, as the curve is the obstruction. For sag curves, sight distance is generally only limited by headlight range.
