Radius of Curve given Cant for Road Solution

STEP 0: Pre-Calculation Summary
Formula Used
Radius of Curve = Pavement Width*Vehicle Velocity^2/(Cant*Acceleration due to Gravity)
R = B*V^2/(h*g)
This formula uses 5 Variables
Variables Used
Radius of Curve - (Measured in Centimeter) - Radius of Curve is the radius of a circle whose part, say, arc is taken for consideration.
Pavement Width - (Measured in Centimeter) - Pavement width is the breadth of the highway pavement.
Vehicle Velocity - (Measured in Kilometer per Hour) - Vehicle Velocity can be described as the amount of distance vehicle travelled in a perticular time.
Cant - (Measured in Centimeter) - Cant of a railway track or camber of a road (also referred to as super elevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges.
Acceleration due to Gravity - (Measured in Meter per Square Second) - The Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
STEP 1: Convert Input(s) to Base Unit
Pavement Width: 6.9 Meter --> 690 Centimeter (Check conversion ​here)
Vehicle Velocity: 80 Kilometer per Hour --> 80 Kilometer per Hour No Conversion Required
Cant: 91.42 Centimeter --> 91.42 Centimeter No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R = B*V^2/(h*g) --> 690*80^2/(91.42*9.8)
Evaluating ... ...
R = 4929.03352546444
STEP 3: Convert Result to Output's Unit
49.2903352546444 Meter --> No Conversion Required
FINAL ANSWER
49.2903352546444 49.29034 Meter <-- Radius of Curve

What are the Factors that Influence the Radius of Curve given Cant for Road?

The radius of curve given cant for road is influenced by the design speed, the cant, the superelevation rate, the sight distance, and the horizontal and vertical curvature of the road.

What is Cant Deficiency?

According to the equation of super elevation, if the speed is more than the design speed, the value of cant will be more (width and radius remaining constant) and if the speed is less than the design speed, the value of cant will be less. This excess or shortage of cant over the equilibrium cant (at design speed) is called cant deficiency of the track.
