How to Map Red Light Cameras

Help and support Tagging help & support

Hello, I am trying to tag red light cameras, but the wiki is a bit confusing.

Here is how I have mapped it currently:

      |
      |   
-B----C------
   A  |
      |

Where:

A: enforcement=traffic_signals (Red light camera; should be mapped separately as it is getting confused with a Flock camera)

C: highway=traffic_signals

Relation: Enforcement

  • A: Device
  • B: From
  • C: To

Is this correct?

Alternatively I believe I might be supposed to map nodes on the ways going up and right as to, but I’m not sure.

Looks correct to me. The to is optional when the red light camera is next to the traffic signal which doesn’t seem to be the case here.
Since it applies to all directions, the to member must be placed on a common node for all directions, the latest of which is the crossing, so your tagging is fine.
Your case is closer to example 1 than example 2.

Thanks for contributing to OSM!
