When you will observe the road far ahead of the front end of your car and keep proper distance between other cars, then you will have enough time for thinking and enough space for braking. But when intense situation happens, then the thinking and braking are solidified in one desperate move: to avoid a collision.
At 20 mph, the average thinking distance is around 20 feet, while the braking distance is approximately 20 feet as well. Therefore, the overall stopping distance for a vehicle traveling at 20 mph would be around 40 feet.
Hand-eye coordination, thinking distance, drunkenness, tiredness, if your on drugs, if your listening to music/being distracted. Thats just about it Also speed and road conditions affect braking distance
Thinking distance refers to the distance a vehicle travels from the moment a driver perceives a hazard until they physically react, such as by braking. It is influenced by factors like reaction time and speed. A longer thinking distance can increase the overall stopping distance of a vehicle.
driving safely Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires What factors affect the thinking distance:
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop.
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.
The minimum distance in which a vehicle can be brought to rest in an emergency from the moment that the driver notices danger ahead. Stopping distances of vehicles can be estimated by using the formula: stopping distance = thinking distance + braking distance The thinking distance is the time taken for the driver to react by applying the brakes of the vehicle. This is known as the reaction time, and is about 0.1-0.3 seconds. As a general rule the breaking distance becomes four times greater as the speed of the car is doubled.I found this info athttp://www.tiscali.co.uk/reference/encyclopaedia/hutchinson/m0030390.html
For a car with good brakes and a length of 4m, a dry road with a driver with average reaction time it will take approximately 36m/118 feet/nine car lengths for it to stop. This can be divided up into two sections the thinking distance/reaction distance of 12m and a braking distance of 24m. Like the previous answer stated the braking distance can be changed depending on the road surface type and weather conditions or if the car is fitted with an Anti-lock Braking System Thinking distance can be increased by drinking alcohol or taking some types of drugs.
On dry, level pavement, with decent tires? About 120 feet. Many things affect this calculation. With worn tires the distance can increase to 210 feet. Dirt roads require longer braking distances than pavement. Ice can increase the braking distance by hundreds of feet. Braking down a hill, depending upon the slope, can double the braking distance, whereas braking up hill can halve that distance. If you lock the tires, you typically increase the braking distance. You can reduce the distance by pumping the brakes. Anti-lock brakes allow the tires to slip, which decreases the braking distance. Extra weight in the vehicle increases the braking distance. Refer to the link below for calculating the braking distance at different speeds with different tire wear on dry, level pavement.
On dry pavement in the average car it will take 60 ft of thinking about it, & 180 ft of braking for a total of 240 ft. Double the braking distance on wet pavement for a total of 420 ft. On snow it is anyone's guess.
Braking distance
Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.
