Interesting traffic signal and sequence

[M3019C LPS20]

When I lived in New York City, I came across various traffic signal configurations, and some were rather interesting to me. I've also seen several interesting sequences. There's one in particular that I am fond of.

The traffic signal is composed of two 8" (sometimes 12") sections. Each section represents a red indication. The top indication is a steady red, while the indication below it flashes. This kind of traffic signal is rather common to see in various locations of the city of New York, and it either faces a driveway of a small business, such as a car wash, for example, or a street that has little vehicular traffic. The sequence is interesting.

-Steady red

-Flashing red

-Transition from flashing red to steady red (no overlap)

-Sequence repeats

It's equipped with ordinary three-section traffic signals, and the flash rate of the bottom section is generally in synchronization with the flash rate of a flashing "DONT WALK" clearance (if a pedestrian signal is present).

Below, are couple of links to street views (from Google Map) of signalized intersections that use this kind of traffic signal.

First one from Staten Island. At Richmond Avenue and Sylvia Street.

Is anybody else aware of these?

I know of a couple in Baltimore. The one I can remember better is on The Alameda at Winston Av. Does pretty much the same thing you outlined.

The only difference I notice is that both indications are lit at the same time (both are steady I presume). Most in the city of New York show only the top indication as illuminated. The bottom indication flashes on its own.

There are, though, a couple of intersections that I know of that show both signal indications illuminated (only steady). The bottom indication, of course, flashes on its own. Here's an example at Grand Army Plaza in Brooklyn, New York...

Tucson, AZ has a variation of this although the top and bottom signal sections red (the top is a solid red, the bottom is a flashing red, with the center amber).  It is also accompanied by a "Yield To Oncoming Vehicles On Flashing Red" sign.
