5.1.4 Route calculation and recalculation
Your software calculates the route based on your preferences:
• Route planning methods:
•
: Gives a quick route if you can travel at or near the speed
limit on all roads. Usually the best selection for fast and normal cars.
•
: Gives a route that has the smallest total distance of all
possible routes. It can be practical for slow vehicles.
•
: Gives a quick but fuel efficient route based on the fuel
consumption data given in Routing settings (page 107). Travel cost
and
CO

emission calculations are estimations only. They cannot take
elevations, curves and traffic conditions into account.
•
: For vehicle types where Green routing is not available,
this method combines the benefits of Fast and Short: The software
calculates as if it were calculating the Fast route, but it takes other roads
as well to save fuel.
•
: Results in a route with fewer turns and no difficult
manoeuvres. With this option, you can make your software to take, for
example, the motorway instead of a series of smaller roads or streets.
