4.6.3.9 Velocity/distance correction factor
A correction factor shall be applied to the measured braking distance if the velocity as checked by the
timing device is not precisely as specified in TBIS 4210-2:2016, 4.6.8.1.1.
The corrected braking distance shall be determined from Formula (1):

where
S c is the corrected braking distance (m);
S m is the measured braking distance (m);
V s is the specified test velocity (m/s);
V m is the measured test velocity (m/s).
