The equation that links stopping distance, thinking distance, and braking distance is given by:
Stopping Distance = Thinking Distance + Braking Distance.
Thinking distance is the distance a vehicle travels while the driver reacts to a hazard, while braking distance is the distance traveled while the vehicle comes to a complete stop after the brakes are applied. Together, they represent the total distance required to stop a vehicle safely.
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.
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.
The stopping distance of a car can be determined by considering the car's speed, reaction time of the driver, and the braking distance required to come to a complete stop. The stopping distance is the sum of the reaction distance (distance traveled during the driver's reaction time) and the braking distance (distance traveled while the brakes are applied). It can be calculated using the formula: Stopping distance Reaction distance Braking distance.
Stopping Sight 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.
The total stopping distance includes the perception distance, reaction time and braking distance. The distance that your vehicle is traveling and then pressing on the brake after seeing a hazard, is the total stopping distance.
Perception Distance + Reaction Distance+ Braking Distance.
Perception Distance, Reaction Distance and Braking Distance
Stopping a vehicle from 20 miles per hour under good conditions typically requires about 60 to 80 feet, depending on the driver's reaction time and the vehicle's braking efficiency. The total stopping distance includes both the thinking distance (the distance traveled while the driver reacts) and the braking distance (the distance required to come to a complete stop). The figure of 186 feet seems excessively high for that speed under good conditions, as most estimates place it significantly lower.
The stopping distance of a vehicle can be determined by considering the reaction time of the driver, the braking distance of the vehicle, and the speed at which the vehicle is traveling. The stopping distance is the sum of the distance traveled during the driver's reaction time and the distance traveled while the vehicle is braking to a complete stop. It is important to factor in variables such as road conditions, weather, and the condition of the vehicle's brakes when calculating stopping distance.
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
Stopping distance for a motor vehicle is a combination of two factors.First the reaction time of the driver.Then the braking distance of the vehicle once the driver has reacted and applied the brakes.The two equal the stopping distance.
