Psychological Widening at Horizontal Curves Solution

STEP 0: Pre-Calculation Summary

Formula Used

Psychological Widening at Horizontal Curves = Velocity/(2.64*sqrt(Mean Radius of Curve))
W_ps = v_vehicle/(2.64*sqrt(R_mean))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Psychological Widening at Horizontal Curves - (Measured in Meter) - Psychological Widening at Horizontal Curves is the widening of the pavement at horizontal curves to provide a comfortable and safe driving experience.
Velocity - (Measured in Meter per Second) - Velocity is the rate of change of an object's position with respect to time, used in superelevation design to ensure safe and efficient traffic flow.
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

Velocity: 28.23 Meter per Second --> 28.23 Meter per Second No Conversion Required
Mean Radius of Curve: 340 Meter --> 340 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_ps = v_vehicle/(2.64*sqrt(R_mean)) --> 28.23/(2.64*sqrt(340))

Evaluating ... ...

W_ps = 0.579919206839078

STEP 3: Convert Result to Output's Unit

0.579919206839078 Meter --> No Conversion Required

FINAL ANSWER

0.579919206839078 ≈ 0.579919 Meter <-- Psychological Widening at Horizontal Curves

Distance between Front and Rear Wheel

Go Distance between Front and Rear Wheel = 2*Radius of Outer Track Line of Front Wheel*Mechanical Widening on Horizontal Curves-Mechanical Widening on Horizontal Curves^2

Ruling Minimum Radius

Go Ruling Minimum Radius = Velocity^2/([g]*(Rate of Super Elevation+Coefficient of Lateral Friction))

Mechanical Widening needed for Large Radius of Road Curve

Go Mechanical Widening on Horizontal Curves = (Number of Lanes*Distance between Front and Rear Wheel^2)/(2*Mean Radius of Curve)

Psychological Widening at Horizontal Curves

Go Psychological Widening at Horizontal Curves = Velocity/(2.64*sqrt(Mean Radius of Curve))

Psychological Widening at Horizontal Curves Formula

Psychological Widening at Horizontal Curves = Velocity/(2.64*sqrt(Mean Radius of Curve))
W_ps = v_vehicle/(2.64*sqrt(R_mean))

What is Psychological Effect?

Psychological effect occurs when vehicles need more width to cross or overtake an other vehicle on the horizontal curve than straight path.
