We see them here quite often… traffic signals and than a solid stop line or give_way right at the crossing. Seen a few sub-signed and ignored for tagging but now is the time. This traffic signal with stop sign below is accompanied with the text saying that if the lights are off or blinking/flashing you have to stop (at the mark). Thought I’d seen a topic touching on this but could not retrace. TagInfo had just one entry of stop:conditional for bicycle so cooked up this
stop:backward:conditional=yes @ “con semaforo spento o lampeggiante”
All traffic light installations in the Netherlands have give-way sign’s so that also if the traffic lights are not working which is typically very infrequent, no additional sign to explain this.
Does the traffic signal regularly turn off or go into a flashing mode, or is the signage there just to remind a motorist what to do in the event of the lights being off or flashing? E.g. a power or controls failure?
If it’s the latter case I wouldn’t bother attempting to map this. We have the same traffic rules here, that a non-functional traffic signal and/or a flashing red must be treated like a stop sign. I don’t think we should attempt to map these sorts of traffic rules; it would be like adding tags explaining to ‘go’ when the light is green.
If the signals are regularly deactivated or set to flashing mode, for instance at night when traffic is much lighter, then it’s definitely worth tagging traffic_signals:operating_times=*.
where the stop or yield only applies when the signal is off or flashing. Makes sense to explore a *:conditional tag. Maybe something like highway=stop + condition=signal_off or similar? Curious how others are tagging this too.
