vs enforcement relations

It looks like Relation:enforcement is more accurate than Tag:highway=speed camera. Which one should we use? --Jesper Cheetah 06:47, 11 November 2009 (UTC)

Both, speed camera for the node (i.e. for rendering), enforcement for complete information about the speed camera, such as where it measures from, and speed limit. --Skippern 12:24, 11 November 2009 (UTC)
My 0.02 € : you should not use this tag ! We are not tagging only for rendering ! This way of tagging is usefull as you can't know the maxspeed / the side checked.

Red light cameras

How do you tag red light cameras that are for catching drivings going through a red light? Smsm1 (talk) 11:56, 22 February 2013 (UTC)

Of course, you should use a relation:enforcement (type=enforcement; enforcement=traffic_signals) but I agree that it is unclear how to tag the device itself. I've found the following in taginfo: highway=red_light_camera, device=red_signal_camera, man_made=redlight_camera, enforcement_camera=yes, and similar combinations. So apparently there is no single preferred solution at this point in time. There are also places where the same camera is used to enforce speed and traffic lights. How about defining a set of new tags using man_made=enforcement and enforcement:device=camera? The enforcement relation will explain whether the camera is triggered by excessive speed or by passing a red traffic light. Other devices also exist, e.g. flashing lights or a sign that displays the measured speed. --Biff (talk) 06:21, 5 July 2013 (UTC)


for speed camera only that show the speed. This camera are fix and don't move with time. maybe traffic_calming is more indicated than police camera. -Yod4z (talk) 13:19, 27 March 2015 (UTC)

Overhead Speed Cameras?

Almost all speed cameras in Japan are over the road on a gantry that spans both sides of the road - both for narrow trunk roads and for motorways. How do I tag support for that? there is usually one for each lane as well. Javbw (talk) 04:05, 11 July 2015 (UTC)

mobile speed limit enforcement

Just wondering if a place where cops are used to be in order to monitore speed limit (and write tickets) could be add? I know it is just probability but helpfull to slowdown and save money ;)
