Psychological Widening on Horizontal Curves Solution

STEP 0: Pre-Calculation Summary

Formula Used

Psychological Widening on Horizontal Curves = Speed of Vehicle/(9.5*(Radius of Curve for Road)^0.5)
W_ps = v/(9.5*(R_t)^0.5)
This formula uses 3 Variables

Variables Used

Psychological Widening on Horizontal Curves - (Measured in Meter) - Psychological Widening on Horizontal Curves is the extra width of pavement provided for psychological reasons such as overhangs of vehicles, greater clearance for crossing.
Speed of Vehicle - (Measured in Kilometer per Hour) - Speed of Vehicle is defined as the instantaneous speed of an individual vehicle as it passes a speed Measurement point or as measured in a speedometer.
Radius of Curve for Road - (Measured in Meter) - Radius of Curve for Road can be defined as the radius at which the spiral is joined.

STEP 1: Convert Input(s) to Base Unit

Speed of Vehicle: 50 Kilometer per Hour --> 50 Kilometer per Hour No Conversion Required
Radius of Curve for Road: 300 Meter --> 300 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_ps = v/(9.5*(R_t)^0.5) --> 50/(9.5*(300)^0.5)

Evaluating ... ...

W_ps = 0.303868562731382

STEP 3: Convert Result to Output's Unit

0.303868562731382 Meter --> No Conversion Required

FINAL ANSWER

0.303868562731382 ≈ 0.303869 Meter <-- Psychological Widening on Horizontal Curves

(Calculation completed in 00.004 seconds)

< 3 Extra Widening on Horizontal Curves Calculators

Total Extra Widening required on Horizontal Curves

Go Total Extra Widening Required on Horizontal Curves = ((Number of Traffic Lanes*(Length of Wheel Base as per IRC^2))/(2*Radius of Curve for Road))+(Speed of Vehicle/(9.5*(Radius of Curve for Road^0.5)))

Total Extra Widening required on Horizontal Curves wrt Wm and Wps

Go Total Extra Widening Required on Horizontal Curves = (Psychological Widening on Horizontal Curves+Mechanical Widening on Horizontal Curves)

Psychological Widening on Horizontal Curves

Go Psychological Widening on Horizontal Curves = Speed of Vehicle/(9.5*(Radius of Curve for Road)^0.5)

Psychological Widening on Horizontal Curves Formula

Psychological Widening on Horizontal Curves = Speed of Vehicle/(9.5*(Radius of Curve for Road)^0.5)
W_ps = v/(9.5*(R_t)^0.5)

Why should the psychological widening be added to the mechanical widening?

The widening required to provide for the greater maneuverability of the steering at a higher speed to allow for the extra space required for the overhang of vehicles and to provide greater clearance for the crossing of vehicles.
