A road is having a horizontal curve of 500 m radius on which a super-elevation of 0.085 is provided. The coefficient of lateral friction mobilized on the curve when a vehicle is traveling at 150 km/h

The points controlling the alignment of high ways are known as

The above figure represents which type of road pattern?

The longitudinal space separating dual carriage ways is known as

The Kerb which prevents encroachment by the parking vehicles is known as

Central road fund was created in the year

The slope provided to road surface in the transverse direction to drain the rain water from road surface is called

A road 10 m wide is to deflect through and angle of 65° with the centreline radius 350 m. A transition curve is to be used at each end of a circular curve of such a length that the rate of gain of radial acceleration 0.4 m3/s, when speed is 60 km/h. Find the shift of the transition curve

Find minimum sight distance to avoid head on collision of two cars approaching at 90 km/h and 60 km/h. Given that, reaction time of driver t = 2.5 seconds, coefficient of longitude friction f = 0.7 and brake efficiency of 50% in either case.

The centrifugal ratio of a vehicle is 0.25, width of vehicle is 2.4 m, height of vehicle to its CG is 4.2 m, lateral friction is 0.15, assuming no super-elevation, then
