Web3.16 Calculating the safe stopping distance. The deceleration values are those recommended by Austroads (1993), and the reaction time is assumed to be 2.0 seconds. Using the charts in section 3.15 and the formula below, the required stopping distance at various speeds are shown in the following table. Where: S = stopping distance (m) WebThe table below shows the distances it takes an average car to come to a stop on dry pavement from different speeds, including the distance traveled for just one second of perception and reaction time: Notice that when you double your speed – say, from 30 mph to 60, or 40 to 80 – your total stopping distance more than doubles: it triples!
