Mechanical Widening needed for Large Radius of Road Curve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mechanical Widening on Horizontal Curves = (Number of Lanes*Distance between Front and Rear Wheel^2)/(2*Mean Radius of Curve)
W_m = (n*l_fr^2)/(2*R_mean)
This formula uses 4 Variables

Variables Used

Mechanical Widening on Horizontal Curves - (Measured in Meter) - Mechanical Widening on Horizontal Curves is the process of increasing the pavement width on horizontal curves to ensure safety and comfort of vehicles.
Number of Lanes - Number of Lanes is the total number of lanes on a road or highway, including both directions of travel, considered in superelevation design.
Distance between Front and Rear Wheel - (Measured in Meter) - Distance between Front and Rear Wheel is the horizontal distance between the front and rear wheels of a vehicle on a curved road section.
Mean Radius of Curve - (Measured in Meter) - Mean Radius of Curve is the average radius of a curve section in road design, used to calculate superelevation and widening of the road.

STEP 1: Convert Input(s) to Base Unit

Number of Lanes: 9.004875 --> No Conversion Required
Distance between Front and Rear Wheel: 23.5431 Meter --> 23.5431 Meter No Conversion Required
Mean Radius of Curve: 340 Meter --> 340 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_m = (n*l_fr^2)/(2*R_mean) --> (9.004875*23.5431^2)/(2*340)

Evaluating ... ...

W_m = 7.34000017879904

STEP 3: Convert Result to Output's Unit

7.34000017879904 Meter --> No Conversion Required

FINAL ANSWER

7.34000017879904 ≈ 7.34 Meter <-- Mechanical Widening on Horizontal Curves
