Question 1
A slow-moving vehicle at a speed of 84 kmph requires a clear spacing of _____ (in m) to overtake. (length of wheelbase = 6 m.)
Question 2
For the computation of safe passing sight distance, the eyelevel of the driver above the road surface and the height of the object is (in m.).
Question 3
A vehicle travelling at 70 kmph, comes to halt after 3 seconds on the application of the breaks. The skid distance (m) travelled by vehicle is?
Question 4
In a two-way, one-lane road, the design speed is 60kmph. If the reaction time is 4 seconds & coefficient of friction is 0.4, then intermediate sight distance (ISD in m) for the road is equal to?
Question 5
To avoid head on collision of two cars approaching from the opposite directions at 72 kmph and 54 kmph, the minimum sight distance should be____m. (Assume reaction time of 2.5 seconds, f=0.7, brake efficiency of 60 percent in both the cases) (g=9.81m/s2)
Question 6
A fast moving vehicle travelling a speed of 70 kmph is intending to overtake a slow-moving vehicle travelling with a speed of 40 kmph. To assess the overtaking opportunity the fast-moving vehicle travels a certain distance during the reaction time of 2 seconds. The distance at this moment between the two vehicles is 15 m. The overtaking vehicle then accelerates at the rate of 0.99 m/s2 and overtake the slow-moving vehicle to a position such that at this instant, the distance between the two vehicles is 20m. For the case of two-way traffic, the overtaking sight distance is ________ m
