Initial driver reaction time

WebbThe driver of a car travelling at 20 meters per second has a reaction time of 1.2 seconds. The car’s brakes decelerate the car at 4.5 meters per second squared once they are activated. What is the car’s stopping distance to the nearest meter? Okay, so in this … Webbreaction time. The third issue is a determination of the actual maximum allow able perception-reaction time for the various standards. The findings of the research indicate that the specification values for perception-reaction time are too low for the stopping-sight-distance design standards and the vehicle-clear ance-interval standard.

The reaction distance describes the distance you will travel from the time you notice the hazard and the time you physically apply the breaks. Perception distance: the time from when your eyes spot a hazard and your brain registers it. This takes the average driver about 1 ¾ seconds. At 55 mph, this is about 142 feet.

WebbDriver reaction time. The reaction time increases proportionally with the speed of the car, which means that if you are travelling at 100 km/h, the reaction time is twice as long as if you are travelling at 50 km/h. Reaction time varies slightly from person to person but is normally 0.5-2 seconds. People aged 45-54 have the best reaction time. WebbPro Drifter Reacts to Initial D!
