12-8-8 signals and other 8/12 arrangements

[Ian]

There is a set of 12-12-8" signals facing each direction of SR 352 where it passes under a set of railroad tracks in Malvern, PA. These signals are here to stop traffic so pedestrians can cross under the underpass, as there isn't much horizontal clearance.

This is a rather odd find... A 12-8-8 with a 3M red section. There are two of them at this intersection. Why is programmable visibility in use at this intersection anyway? Is there something I'm not seeing?

If I were to guess, it's so that traffic turning left onto Merrick Road from either side street doesn't think the red is for them. The 3M red sections are likely masked so that only traffic behind Merrick's stop line can see them.

Sorry if this was mentioned but downtown Newberg still has two and Sherwood still has a pedestrian crossing with this design.
