"from non-U.S. editors"

A variant that comes to mind is a traffic signal that is a bit like the emergency variant, or a railway crossing signal: normally off, but whenever a bus approaches from the (a not-necessarily-bus-only) side street, it first blinks yellow (here, that's "may proceed with extra caution") for some seconds, and then changes to red to facilitate a speedy passage for the bus; once the bus has passed the detector after the signals, the lights turn back to flashing yellow, and soon off. (There's also a timeout in case the outbound bus isn't detected properly.) At rush hour, the signals can activate on average every few minutes, or every ten minutes late in the evening, or even more rarely. Some of these are for trams, some for buses.

I've since used traffic_signals=bus_priority and traffic_signals=tram_priority for these. Alv (talk) 05:19, 6 May 2013 (UTC)

Nighttime-only blinking

I'm stuck on Way 19299657 (iD, JOSM, Potlatch2, history, XML), which has ordinary traffic lights that are set to flash yellow (flashing red on cross streets) at night, when there is little cross traffic. – Minh Nguyễn (talk, contribs) 06:04, 3 September 2013 (UTC)


How should we tag British wig-wags at bridges and fire stations? --Amaroussi (talk) 12:48, 17 November 2015 (UTC)
