WebReaction time. One reason for this increased risk is reaction time—the time it takes between a person perceiving a danger and reacting to it. Consider this example. Two cars of equal weight and braking ability are travelling along the same road. Car 1, travelling at 65 km/h, is overtaking Car 2, which is travelling at 60 km/h. WebExplanation: The total stopping distance is the sum of the reaction distance and the braking distance. These values are listed in Table 1 for various reaction times. The maximum reaction time listed in the table is 1.00 seconds. Since this question pertains to a reaction time of 1.5 seconds, one will have to extrapolate to determine the answer ...

WebTotal Stopping Distance = 120.9 ft + 24.2 ft + 134.4 ft = 279.5 ft Almost half the distance is created by driver reaction time. This is one reason that it is vital to have a good estimate of speed of human response. Below, I give some values which I have derived from my own experience and from an extensive review of research results. 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.
