4.9.3 Vehicle speed determination
Speed curve for 100 m distance according to the following table
- Measure 100 m test distance at usage location with a tape measure
- Cover the test distance at the constant, specified speed and measure the
necessary travel time with a stopwatch
- Insert the value determined into the formula above
- e.g. 60 seconds = 100 / 60 x 3.6 = 6 km/h
If the determined vehicle speed deviates from the vehicle speed of the control
unit, the vehicle speed must be recalibrated.
