HORIZONTAL CURVE TABLES
The horizontal curve tables assume an initial crowned cross section of 3.0% to calculate the curve data. Adverse crossfall can be used when the tables give superelevation as -3.0% (in bold print). It is assumed that the design is on level ground and no …

Safe Speed For Horizontal Curve Calculator
When driving on a road with a horizontal curve, the vehicle's speed must be carefully managed to ensure safety. Horizontal curves are standard features in road design. They are characterized by a bend or deviation from a straight path. These curves can be dangerous if drivers do not reduce their speed appropriately due to the lateral forces ...

Horizontal Alignment of Highways
8. Assertion (A): When a sharp horizontal curve is to be introduced on a road which already has the maximum permissible gradient, the gradient should be decreased. Reason (R): The gradient should be decreased to compensate for the loss of tractive effort due to the introduction of sharp horizontal curve on the road.
