It's just that cars must stop and pedestrians must clear the intersection immediately when an emergency vehicle like a fire truck or ambulance approaches. The blue emergency light is for ambulances and the red F beacon is for fire trucks. This will turn the blue light and the red "F" beacon on, causing the signals to turn red and the polara navigator to say "Emergency vehicle approaching! Clear intersection immediately!" The blue light and "F" beacon turning on are for the emergency vehicles to pass through, the polara navigator saying those words are for the pedestrians to clear the intersection right away.

You are correct. They use Rapid Tick #2 there.

Less than a month after I ask this, I decided to take alook into the software for these ez navigator buttons. I found that if I opened the exe file for the program in 7zip, I was able to find 3 files. The last of these files couldn't be opened as an archive, but did contain standard pcm wav data. So I put it through a different kind of unpacker/ extractor program and told it to search for the patterns that make up wav files, and sure enough, all the sounds were there, including at least 1 that isn't in this video.

I just download the yt video as an mp3 and then trim it to the audio file I want

I think the technicians should pick the custom walk that says "walk sign is on".

@@Trafficlightiosproductionsalt They set it to a rapid tick sound that sounds like a machine gun

@@VOLTRONDEFENDER4440I have heard Locate Tone #2 and Rapid Tick #2 in a lot of Canadian intersections. I have heard some clearance tones in NYC.

In the busy city I live in, which is one of the two major cities, they will always use "walk sign is on".@@VOLTRONDEFENDER4440
