Geometry
Keep It Simple/Stupid (KISS)
"As simple as possible, as complex as necessary"
KISS is keeping the road geometry as simple as possible, without losing the essential driving instructions.
More info, see the KISS page.
Filter lanes
Filter lanes are not mapped.
Filter lanes don't fit the KISS principle because they are the cause of very complex situations that are hard to manage, while they don't add a lot of value in most routing instructions. Short segments and extra splits can have a negative influence on routing (extra penalty, incorrect average speeds, ...).
Of course, there is always an exception. If the choice of a filter lane must be made more than 50 meter before coming to the crossing AND the main road and filter lane are divided by obstacles (concrete blocks, ...), it should be mapped.
Ring roads
There are roads that could be classified by multiple street types. We think of ring roads (R-roads) which sometimes can also be a N-road categorized as Major Highway. For example, the ring road of Leuven, the R23, has long segments which are also N2 or N3. In these cases we categorize the ring road as Major Highway.
Ring roads which are also freeways, like the R0 of Brussels, are categorized as Freeway.
Roundabouts
If you want to add a roundabout, you firstly draw the roads as a normal crossroad, but don't connect the roads/segments. Secondly you draw the roundabout and WME will connect the crossing roads automatically.
A roundabout must always get a cityname but never a streetname. The reason for this has to do with the navigation instructions and road announcements.
A roundabout always gets categorized as the type of the passing through road.
