Question
Which of the following is equal to the stopping sight distance?
Correct answer
(A) (braking distance required to come to stop) + (distance travelled during the perception-reaction time)
Solution
Stopping Sight Distance (SSD) is the minimum distance available on a highway at any spot to enable the driver to stop a vehicle travelling at design speed, safely without collision with any other obstruction. It is the sum of:
1.Lag distance: distance travelled during perception-reaction time.
2.Braking distance: distance travelled after application of brakes until the vehicle comes to a stop.
