5.1.3 Colour theme in tunnels
When entering a tunnel, the colours of the map change. All buildings disappear,
large objects (such as surface waters or forests) and empty areas between roads
become black.
However, roads and streets keep their original colours from the daytime or night
colour theme currently used.
After leaving the tunnel, the original colours return.
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 Green Routing settings (page 84). Travel cost
and CO2 emission calculations are estimations only. They cannot take
elevations, curves and traffic conditions into account.
•
: 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.
• Vehicle types:
•
:
• Manoeuvre restrictions and directional constraints are taken into
account when planning a route.
