Example Sentences

On account of the variation in speeds of the vehicles, the superelevation for curves on a highway can only be designed to suit the average speed.

From American Rural Highways by Agg, T. R. (Thomas Radford)

It is good practice to provide the theoretical superelevation on all curves having radii greater than 300 feet for vehicle speeds of the maximum allowed by law, which is generally about 25 miles per hour.

From American Rural Highways by Agg, T. R. (Thomas Radford)

This tendency is counteracted by designing the cross section with superelevation.

From American Rural Highways by Agg, T. R. (Thomas Radford)

Theoretically, the amount of the superelevation should increase with a decrease in the radius of the curve and should also increase as the square of the speed of the vehicle.

From American Rural Highways by Agg, T. R. (Thomas Radford)

At turns approaching ninety degrees, the curve is likely to be of such short radius that it is impossible to maintain the ordinary road speed around the curve, even with the maximum superelevation permissible.
