Vehicle Stopping Distance Calculator

Posted by Dinesh on

This calculator calculates the stopping sight distance, stopping sight distance using vehicle speed (v), coefficient of friction (f), grade of road (g), perception/reaction time (t) values.

Vehicle Stopping Distance Calculation

m/s
%
Downhill
sec
meter
feet

Formula:

Stopping Distance =(v×t) + { v² / [2×g×(f±G)] }

Where,
g - gravity (9.8)
v - Vehicle Speed
t - perception Time
G - Grade of Road
f+G - Grade of Uphill
f-G - Grade of Downhill
