The minimum stopping sight distance (SSD) on a level road depends mainly on:
Speed and braking distance
Speed and gradient only
Speed, reaction time, and braking distance
Speed, pavement type, and shoulder width
If the speed of a vehicle is doubled, the stopping sight distance will:
Double
Increase four times
Remain the same
Increase eight times
Which of the following is most critical for the design of overtaking sight distance (OSD)?
Driver's reaction time
Speed differential between overtaking and overtaken vehicles
Road camber
Vehicle acceleration only
The headlight sight distance on a road is usually considered equivalent to:
Overtaking sight distance
Intermediate sight distance
Stopping sight distance
Safe braking distance
Superelevation is provided on horizontal curves to:
Reduce centrifugal force
Counteract the effect of centrifugal force
Reduce friction between tyres and pavement
Increase vehicle speed
The minimum radius of a horizontal curve depends on:
Vehicle length and road gradient
Design speed, superelevation, and side friction
Road camber and lane width
Traffic volume and vehicle acceleration
Transition curves are provided in horizontal alignment to:
Connect two straight roads directly
Provide gradual introduction of centrifugal force
Reduce the pavement cost
Avoid overtaking on curves
The camber provided on the road surface is mainly for:
Increasing sight distance
Reducing pavement thickness
Facilitating drainage of rainwater
Providing comfort to the driver
The shoulder on a highway cross-section is meant for:
Parking of vehicles
Emergency use and lateral support to pavement
Increasing carriageway width for traffic
Aesthetic purpose only
The right of way (ROW) in a highway cross-section refers to:
Width of the carriageway only
Total land acquired for the road, including shoulders and drains
Distance between the two carriageway edges
Lane width plus median width
