Parameters
duration
The detour duration for a passenger car in seconds. The detour duration is the value added to the estimated time of arrival (to the final destination), after a point of interest has been added to the route. If the route that passes through the found point is faster than the original one, the detour duration value is negative.
distance
The detour Distance is the added value to the route length, after a point of interest has been added to the route. If the route that passes through the found point is shorter than the original one, the detour distance value is negative.
offset
The length of the route part from the starting point to the detour starting point.
