The alternating, or wig-wag, flashing red light means "stop and remain stopped". This is causing a problem with the HAWK pedestrian signal, in which motorists are confused as to what they are supposed to do when the two red lights go from a solid red to a flashing red. (The purpose of the light is to speed up traffic after the pedestrian has safely crossed, as opposed to the standard R-Y-G signal that requires a full stop until the light turns green.) I know WSDOT has required HAWK signals to flash both red lights together, not alternately, to avoid confusion; however ODOT continues to allow the alternating flashing.
The school bus uses the signal properly just like a railroad crossing.
As for the signal in Colorado I wonder if it is some kind of experimental or test signal. In Oregon we have this weird hybrid signal arrangement at two intersections in Beaverton for the WES commuter rail spur.
