6.1.4 Route calculation and recalculation
iGO primo 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 Route settings (page 104). Travel cost and CO
2
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: iGO primo 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 iGO primo to take, for example, the
motorway instead of a series of smaller roads or streets.
• Vehicle types:
When creating a new vehicle profile, select one of the below vehicle types. Besides
the below mentioned conditions, dimension, weight and freight hazard restrictions
can also be taken into account when planning a route.
•
:
• Manoeuvre restrictions and directional constraints are taken into account
when planning a route.
• Roads are used only if access for cars is allowed.
• Private roads and resident-only roads are used only if they are inevitable
to reach the destination.
• Walkways are excluded from routes.
•
:
• Neither manoeuvre restrictions nor directional constraints are taken into
account when planning a route.
• Roads are used only if access for pedestrians is allowed.
• Controlled-access roads are excluded from routes.
• A private road is used only if the destination is there.
