Stopping distance

There can be several reasons for tailgating. Preventing cut ins[ edit ] Tailgating can occur when a vehicle attempts to prevent another vehicle on the right or left from cutting in front of them. The tailgating or preventing vehicle will drive as close as possible to another leading vehicle to prevent the side vehicle from cutting in. Like all forms, this practice of tailgating is illegal and attempts to force the side vehicle to slow down and get into the line of traffic behind the tailgating vehicle.

Stopping distance

This calculator is designed to give an accurate projection of stopping distance of a normal passenger vehicle, based on data entered.

There are three sections for data. The first has to do with vehicle speed. The second is the co-efficient of friction and the third is the stopping distance. You may enter data in any of the boxes above.

The quantity will be calculated in the other unit fields within that section. Then click on the active text or the calculate box for either stopping distance or vehicle speed to calculate that quantity. The quantities will not be forced to be consistent until you click on the quantity to be calculated.

If the fields are empty, you may click on either calculate text or button to fill in default information. That information is NOT as of yet calculated until the section having one or more empty fields is clicked.

You may change the data in any field, one at a time and then click on either of the calculate text or button areas.

The calculations are extensive! As of October,we are scheduled to begin work of additional capability to this calculator; that of Anti-Lock computer assisted disc brakes as opposed to conventional brakes.

As of Septemberwe are told that this calculator has been used in 17 court cases. If you are an attorney looking to use this in a case, please do not request assistance from us. We don't have the time. Do the research to see if this has been used in a jurisdiction that is similar to yours.

Then and only then, we will assist you, at our normal technical time rates, if you wish to retain us. To the best of our knowledge, it is a "one of a kind" calculator that is extremely accurate; we neither have the manpower nor financial resources to authenticate the accuracy or validity.

It is offered for use on the Internet as a public service "as is". Note that this calculation implies a stopping distance independent of vehicle mass and of driver reaction time.

It also implies a quadrupling of stopping distance with a doubling of vehicle speed. One experiment with trained drivers asked the drivers to stop a vehicle on signal by 1 locking the wheels and 2 stopping as fast as possible without locking the wheels.

On dry flat concrete, the stopping distances were very nearly the same. Both tests yielded coefficients of friction near 0. The coefficient of kinetic friction is considerably less on a wet surface, or similarly less than optimum surfaces or in less than optimum conditions where the water can act as a lubricant.

It is also noted above that worn tires have a considerably smaller coefficient of kinetic friction than static friction. Stopping Distance For A Vehicle Assuming proper operation of the brakes on the vehicle, the minimum stopping distance for a vehicle is determined by the effective coefficient of friction between the tires and the road, and the driver's reaction time in a braking, the Soul of distance skateboarding and LDP.

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. It is primarily affected by the original speed of the vehicle and the coefficient of .

Stopping Distance is the total distance you travel before you hit the brakes plus the distance you travel while the brakes slow you down.

Thinking + Braking Distance = Overall Stopping Distance. How to remember Stopping Distances. When admiring a new car, no one ever asks the owner how well its how well does it goes.

Many drivers, drive in a false belief that if the car in front suddenly started braking, they would react and brake and end up stopped the same distance apart.

Sight Distance Explained. By Jonah Finkelstein, EIT. According to the American Association of State Highway and Transportation Officials’ (aka AASHTO) A Policy on Geometric Design of Highways and Streets (aka the Green Book), “The designer (of a roadway) should provide sight distance of sufficient length that drivers can control the operation of their vehicles to avoid striking an.

Braking distance ç 5 Similarly, if we increase the speed by 20% (for example from 50 km/h to 60 km/h), then d ˘() 2 k ˘ k. In summary: • A 10% increase in the speed causes a 21% increase in the stopping distance.
