SSC JE 2019-20: Transportation Engg. Quiz-2

The design speed of a highway is 75 km per hour. Assuming other data as per IRC recommendations, which one of the following is the approximate adopted lag distance:

A vehicle moving at 60 kmph speed was stopped by applying brake and the length of the skid marks was 30m. If the average skid resistance of the pavement is 0.70, the brake efficiency of the test vehicle nearly

Calculate the safe stopping sight distance (in m) for the descending gradient of 3% for a design speed of 80 km/h. Take coefficient of friction as 0.35 and total reaction time as 2 seconds.

Which one of the following expression given intermediate sight distance as per I.R.C standards? (SSD : stopping sight distance; OSD: overtaking sight distance)

Which of the following is not included in the PIVE time of driver

Brake is applied on a vehicle which then skids a distance of 12 m before coming to stop. If the developed average coefficient of friction between the tyres and the pavements is 0.3, then the speed of the vehicle before skidding would have been nearly

During a braking test, a vehicle travelling at a speed of 43kmph was stopped by applying brakes fully and skid marks were 7.9 m in length. The average skid resistance of the pavement surface is

Vehicle A travelling at a speed of 60 kmph on a one-way highway decided to overtake a slow-moving vehicle B travelling at a speed of 45 kmph. For this, he slows down it’s speed to 45 kmph and waited for 2 sec. The distance between two vehicles was maintained equal to 20 m. Then the vehicle accelerates at a rate 0.99 m/s² and overtake the vehicle. Calculate the Safe overtaking sight distance required for this purpose.
