DRIVER REACTION TIME Within the driving task, reaction time in response to a particular potential traffic hazard is the time required from the point of initial detection of the hazard in one’s field of view, through various stages of evaluation and decision making, to the time that. We surveyed 2, people aged 18 and above and asked them to play the game. We then plotted their reaction time against their age. Your predicted age is the age that most closely matches the age of people with your reaction time.


time of s and a brake-reaction time of LO s. The values do not relate to any specific percentile of driver performance but, rather, were selected as being "large enough to include the time taken by nearly all drivers under most highway conditions.•. to press a pedal as soon as they heard a sound. The estimated reaction time varied from to s, with a mean value of s. A recent study using both a real driving environment and a simulator (10) indi-cates that the reaction time of drivers to an anticipated danger in a real environment has a mean value of s and a standard deviation. A typical reaction time to perceive a threat such as a deer or a child running into the road is about 3/4 second, and then you add another 3/4 second to decide to act and move your foot to the brake pedal – that’s seconds so far. At 55 mph, the distance traveled is feet. Only then does the car begin to slow.


Experiment with different driving speeds, road conditions and reaction times to see the distance it takes to stop your vehicle. It is commonly known that the driver's reaction time may depend on the sex Nearly identical values were obtained at the described test station—Table 1. tr=driver reaction time (varies from 2,5 to 2,8sec) for various sized motorcars and speeds on a flat section of road are given in the graph below.
