Stopping Sight Distance Starter Quiz

Calculate the stopping sight distance on a highway at a descending gradient of 3% for a design speed of 100 kmph. Assume other data as per IRC recommendations.

A vehicle was travelling with a velocity of 65 kmph on a one lane two-way highway. Calculate the stopping sight distance if the reaction time of driver is 2.5 sec and coefficient of longitudinal friction is 0.35 .

Two vehicles are approaching each other at right angle. If stopping sight distance required for both the vehicle is 105.42 m and 85.62 m respectively what is the minimum sight distance required at intersection?

The safe stopping sight distance as recommended by IRC for a design speed of 30 kmph in regard to hill roads is

Calculated Safe stopping sight distance for design speed of 70 kmph for

Case 1: Two-way traffic on a lane road

Case 2: Two-way traffic on single plane road

Assume coefficient of friction 0.35 and reaction time of driver is 2.9 sec 

When a driver drives down the grade at the speed of 40 kmph with coefficient of friction 0.35 , the driver requires braking distance almost twice that required for stopping the vehicle when he travels the up at same speed then grade is (in %)

The stopping sight distance (SSD) for a level highway is 140 m for the design speed of 90 km/h. The acceleration due to gravity and deceleration rate are 9.8 m/s² and 3.5 m/s², respectively. The perception reaction time (in s, round off to two decimal places) used in the SSD calculation is _____________
