How do I calculate stopping distance?

All you need to do is multiply the speed by intervals of 0.5, starting with 2. That’ll give you the stopping distance in feet, which is acceptable for the theory test. For example… There are 3.3 feet in a metre – so divide the distance in feet by 3.3 to get the stopping distance in metres.

What is stopping distance formula?

Stopping distance = reaction distance + braking distance.

What are the factors affecting passing sight distance?

Factors Affecting Overtaking Sight Distance

  • Spacing Between the vehicles.
  • Speed of the vehicles.
  • The gradient of the road.
  • The acceleration rate of the overtaking vehicle.
  • The velocities of the vehicle which is overtaking, overtaken and that coming in the opposite direction.
  • The driver skill.
  • The reaction of the driver.

Why stopping sight distance is greater downhill than uphill?

When riding downhill, the effect of gravity makes it such that you will need a longer distance in which to stop, so on a 15% grade you’ll need about 30% longer to get stopped.

What are the factors affecting stopping sight distance?

Factors Affecting the Stopping Sight Distance on Road

  • The total reaction time of the driver.
  • Speed of the vehicle.
  • Friction between the Tyre and the pavement surface.
  • Break efficiency.
  • The gradient of the road.

What is the difference between sight distance and stopping sight distance?

It is the length of the road ahead visible to a driver at any instance. (a) Stopping Sight Distance: Stopping Sight Distance is the sight distance required for a driver to effectively apply the brakes and stop the vehicle without collision with the obstruction on the road. …

What are the factors affecting passing sight distance and non passing sight distance?

Factors affecting Overtaking Sight Distance:

  • Speed of overtaking vehicle ( V m/s)
  • Speed of overtaken vehicle ( Vb m/s)
  • Speed of opposite vehicle ( V m/s)
  • Reaction time of overtaking vehicle driver.
  • Spacing between the vehicles (S)
  • Acceleration of overtaking vehicle (m/s2)
  • Gradient of the road.

What is over taking sight distance?

The overtaking sight distance is the minimum distance open to the vision of the driver of a vehicle intending to. overtake the slow vehicle ahead safely against the traffic in the opposite direction.

Is SSD is 91.4 m then the value of headlight sight distance is?

[Ans: 132m]. Given: Gradient(n) = -2V = 80 Km/hr. SSD on road with gradient = 132m. Headlight Sight distance = 91.4m.

How many types of sight distance are there?

three types
