Divided roads

[lichauco]

PLEASE ! ! !

Stop taking out the divided roads and replacing with separated roads in the Orlando/Disney Area!

These are divided roads!!! Every other map program shows these as divided why are we making them separated on Waze?

Thank you.

The wiki specifically says that we shouldn't make a road divided just because other maps do so. Direct from the best practices:

A road should not be split because:

• There is a curb or non-drivable media less than 5m wide between lanes of travel. This means a turn lane, even a wide one, between directions of travel, does not count because it is drivable.
• There are a lot of roads intersecting which can only turn onto the nearest direction of travel.
• Google Maps or other mapping source show it as a split road

It also says that they should not be divided unless they show a definite gap in the gps tracks at the 100m zoom level. The best practices state that non-limited access roads should rarely be divided, that is what turn restrictions and the "separating line" checkbox are for. Most of the roads around here have 15 foot medians, which is only 4.5 meters, and hardly any show any gap at all in the gps tracks. I have left the roads divided where a gap was present (IE, 27, parts of 192 and 50).

When we make maps in Waze we aren't trying to make an exact replica of the layout of the roads, we are making navigation data that needs to be easily interpreted by the routing server, users, and AMs. The best practices and forums repeatedly stress that roads should be simplified as much as possible (without compromising navigation) in order to facilitate this.

With Cartouche it was a little bit of a pain when roads only entered one side of a divided highway because the routing server would sometimes ignore turn restrictions, but I have confirmed that turn restrictions entered in Papyrus are obeyed properly by the routing server.
