 # Vehicle Tracking Analyzer

The turning radius used for the vehicle in the Vehicle Tracking function is measured from the center of the front axle.

In some road designing guide books the radius may be measured from the outer edge of the vehicle so this value then needs to be deducted when setting the turning radius in the function.

In addition, if there are drawn templates to follow, we will stribe to follow those by editing the different parameters to fit it as best as possible.

Example:

The lorry in the example above has a minimum turning radius of 10.03 in the template.
The radius set in the guide books for this particular vehicle is 12.00m.

The value of 10.04 is derived from calculating the diagonal from the center of the front axle to the outer front corner.

We use Pythagoras Sentence to calculate the diagonal:
√(1,275m²+1,5m²) ≈ 1,97m

12m - 1,97m = 10,03m.

When the maximum angle of turning close to the angle from center axel to the front corners, this is a fairly accurate approximation. However this is not always correct and must be considers in each case.
