Road shields

Road shields are linked to the street attribute of a segment, this is the full address <Street>+<City>+<County>+<Country>. Setting a shield on 1 segment will set it for all matching segments.

It is recommended that you install the [Road Shield Assistant] script to assist with see current road shields and affects of any changes you make.

Shields on segments

To match with the Road Type convention used in the UK, road shields should be mapped as follows;

Motorway - For use on Motorway with 1 or 2 digitals M1 M42
Motorway (wide) - For use on Motorway with 3+ digits M602 A38 (M)
Primary Route - For use on Major Highway A-Roads that form part of the Primary Route Network A14
Non-Primary Route - For use on all other Minor Highway A-Roads A4030
Junction No. - For use on junction ramps that have signed numbers 21 .

Changing the shield on a segment will change the shield on all segments with the same name, however far away they may be. Likewise, changing the name of a segment will change the shield if the name matches another.

Due to the implementation of this feature, extra care must be made when assigning road shields to segments with an identical street attribute when it changes Road Type, the most likely scenario will be A-roads that change from PRN to non-PRN. Mapped Road Types have no influence on the displayed shield.

At this time (May 2021) road shields do not show on the client app for mapped Primary Street road type but but may be added if needed for turn instructions.

Junction shields should not include the letter J.

Shields on turn instructions

Turn arrows now allow editors to set the visual instructions at a turn. Editors should do their best to match the road sign at the turn. The road shield (1st) and corresponding destination name (2nd) in the Visual instructions field, and any additional destination names in the Towards field.

Road numbers within brackets (A460) should not be included at all as they are not directly off the junction, nor should road numbers be written in the Towards field.

In order to receive the correct turn instructions with road shields on roundabouts make sure to add the turn guidance on the exit turn from the roundabout. The turn guidance from the exit will be copied to the entry one.

Editors should only be used when exits have a signed junction number.
