15.3. Calculation of the driving speed
The driving speed is calculated based on the following formula:
Driving speed (km/)
=
Measured path (m) x 3.6
Time (sec.)
Sample calculation
based on the following data:
Measured path:
100 m
Driving time:
60 sec.
Calculation:
100 x 3.6
=
360
= 6
60
60
The driving speed is therefore 6 km/h.
Conversion of driving time to driving speed
As an alternative to the above calculation, the approximate driv-
ing speed can be taken from the table below:
Driving speed
(km/h)
Time for 100 m
(sec.)
Driving speed
