B. Tangent Run Out
C. Super Elevation Run Off
D. Tangent Distance

A

B

30
Q

The location of super elevation development onto circular curves has been continuous concern to designers throughout the world. This concern is due to the fact that design super elevation is not available for the curve radius at the PC. This results in the vehicle experiencing 2 to 3 sec where lateral acceleration tends to force the driver to adopt a natural spiral curve during entry and exit. This problem can be prevented by:

A. Widen the curve to give drivers this extra width as well as to give additional width for swift path of large vehicles
B. Provide a proportion of super elevation run off. This proportion tends to minimize the adverse effects of lateral acceleration and improves the safety of the transition from tangent to circular curve
C. Provide traffic lights at the point of transition from tangent to circular curve
D. Provide pavement markings at the point of transition from tangent to circular curve
