Note that this is a draft article. This will need to be included in a more accessible article once this has been finalized (most likely into Road types and Road Aspects).
Road shields on Streets
Road shields are connected to street names instead of segments. This means that changing a road shield affect all segments with the same street (name & city) set as primary name. A street can have only one shield. When you change the primary name of a segment, the segment inherits the road shield linked to that new name, if any.
At the moment it is not possible to set a road shield on an alternate name and have the segment use that road shield. Waze is currently working on allowing this. Until this is done, we advise not to touch this feature yet! The only exception to this are road numbers that aren't visible on the street.
We are only interested in adding road shields on the map if they are also visible on the street. Many roads numbers (mostly N100-N999) aren't actually signed in real life and are therefore not useful information for the Wazers.
Take care not to indicate any "direction" on the shield. This direction is intended for other countries who use cardinal directions alongside a road shield (e.g. Route 66 North).
If no road shield is present, road shields are automatically generated based on the name of the street. This will most likely change in the future.
