    Not all ramps are curved. But for the ones that are, the radius of the curve depends on the speed they want people to go on the ramp.

    well you see khawar its too do with friction, by curving the on ramp it helps the vehicle maintain there 'stay' on the road even if it were frictionaless, ie: snowing or raining.

    khawar, are you referring to the exit and entry lanes? The ones that you use to exit or enter the freeway (like the Interstate highways)?

    both have been tilted in specific cases, and they are both tilted for the same reason
