stopping distance depends on which of the following course hero

What does stopping distance depend on?

The stopping distance is the distance travelled between the time when the body decides to stop a moving vehicle and the time when the vehicle stops completely. The stopping distance depends on factors including road surface, and reflexes of the car's driver and it is denoted by d.

What affects stopping distance theory?

The stopping distance formula is best described in this image: The distances shown are a general guide. The distance will depend on your attention (thinking distance), the road surface, the weather conditions and the condition of your vehicle at the time.

What are the 3 parts of stopping distance?

Stopping distance consists of three factors: Driver's reaction time + Brake lag + Braking distance.

What are 3 factors that affect stopping distance?

original speed of the vehicle. the type of brake system in use. the reaction time of the driver/rider. the coefficient of friction between the tyres and the road surface - also known as the traction coefficient.

Which is not a factor in stopping distance?

Braking distance does not depend on your steering technique. Your perception time describes the amount of time it takes for you to identify a potential hazard, change, or traffic signal that will require you to stop your car.

What are two important things about stopping distance?

The factors that affect your vehicle's stopping distance include:Vehicle Weight and Load.Vehicle Age.Brake and Tyre Condition.Road Condition.Weather.Driver Reaction Time.

What is meant by stopping distance?

: the distance that a driver needs in order to safely bring a vehicle to a complete stop.

In which conditions will stopping distance increase?

In poor weather conditions, a car's total stopping distance is likely to be longer for a number of reasons. For a start, poor visibility might mean the driver takes longer to react – increasing his/her thinking distance. But slippery roads caused by rain, snow or ice will also extend the braking distance.

What are the stopping distances for theory test?

Overall Stopping Distance (on dry roads) The factors are easy to remember - just start at 2 for 20mph and add 0.5 for each 10 mph increase in speed. Example: Question: What is the overall stopping distance at 50mph? Answer: Factor for 50mph is 3.5 and so overall stopping distance at 50mph is 50 x 3.5 = 175 feet.

What will affect your vehicle's stopping distance theory test?

Explanation: Having tyres correctly inflated and in good condition will ensure they have maximum grip on the road; how well your tyres grip the road has a significant effect on your car's stopping distance.

What plays a factor in your stopping distance quizlet?

What are factors that affect braking distance? Speed: The higher your speed, the longer your braking distance. Vehicle Condition: A vehicle with worn tires, shock absorbers, or brakes needs a longer stopping distance.

What factors can influence your stopping distance quizlet?

What is stopping distance GCSE?

The braking distance is the distance taken to stop once the brakes are applied. The braking distance increases if: the car's brakes or tyres are in a poor condition. there are poor road and weather conditions (eg icy or wet roads) the car has a larger mass (eg there are more people in it)

What is a critical factor when judging stopping distance?

Of the two, reaction time is the critical factor in determining the distance it takes to stop your vehicle. The more quickly you can perceive a problem and react to it, especially at higher speeds, the better your chances are of avoiding a collision.

How to calculate the stopping distance?

In the book "A Policy on Geometric Design of Highways and Streets", AASHTO gives the formula for calculating the stopping distance. This formula is commonly used in road design for establishing the minimum stopping sight distance required on a given road. With correct parameters, it's a perfect equation for an accurate calculation of the stopping distance of your car.

How many meters does a car travel before it comes to a stop?

Your car will travel 260 meters before it comes to a stop.

What is the distance traveled when you hit the brake?

The distance traveled from the moment you first hit the brake is called the braking distance . The stopping distance, on the other hand, is the total distance traveled during the perception and reaction time summed with the braking distance.

What is the AASHTO formula?

The AASHTO formula is as follows: G is the grade (slope) of the road, expressed as a decimal. It is positive for an uphill grade and negative for a road going downhill; f is the coefficient of friction between the tires and the road .

What is perception reaction time?

Perception-reaction time. Calculating the stopping distance: an example. Even if you're not a driver, you surely know that the car doesn't stop immediately after hitting the brakes. From the moment you spot a potentially dangerous situation, to the moment when the car comes to a complete stop, it travels a certain distance.

What is the period of time that happens after an event?

First of all, some time will pass after the event began to happen, but before you react to it. This period is called the perception time. During this time, the car continues to move with the same speed as before, approaching the child on the road.

How fast can you hit the brakes?

In reality, many drivers are able to hit the brake much faster. You can use the following values as a rule of thumb: 1 second - a keen and alert driver; 1.5 seconds - an average driver; 2 seconds - a driver who is tired, or an elderly person; 2.5 seconds - the worst case scenario.

How long is chapter 1?

Estimated time for Chapter 1: 30 Minutes

Why is it important to quickly and accurately identify speed violators?

to quickly and accurately identify speed violators will allow officers to divide their attention among the other necessary tasks.

What is the purpose of speed measuring device operator training?

The goal of the Speed-Measuring Device Operator Training is to provide knowledge and skills necessary to become more effective in detecting speeding vehiclesand gathering evidence to support a charge of a speed law violation.

Why do drivers use R.A.D.A.R. detectors?

Many drivers use R.A.D.A.R./L.I.D.A.R. detectors to avoid speeding citations. Officers that are proficient in the identification of violators and the estimation of target vehicle speed are not hampered in their enforcement efforts by detectors.

What is speeding in traffic?

Speeding is defined as exceeding the posted speed limit or driving too fast for conditions. Speeding is one of the most prevalent factors contributing to traffic crashes.

What is the critical factor affecting an operator's capability?

A critical factor affecting an operator’s capability is perception-reaction time:

How does perception reaction time affect speed?

The affect perception-reaction time and speed have on a driver’s capability can be illustrated by braking. The average driver requires approximately 1.5 seconds to perceive, react, and apply the brakes. The brakes are not being applied and the vehicle continues to move at the same speed and on the same path toward the hazard during this 1.5 seconds. The distance the vehicle travels during the 1.5 seconds depends upon the speed. Perception-reaction time is only the beginning of the problem. Once the brakes are applied, time elapses before the vehicle comes to a complete stop. The faster the vehicle is moving, the longer it will take to stop. Vehicles moving at higher speeds have more momentum than vehicles at lower speeds. More braking force must be applied to vehicles traveling at high speeds
