Little late here, my email was OOS; but on your original photo of Liberty & Bradford note the round sign on pole on right "STOP Here on RED SIGNAL" I think this was a short-lived experiment in the city (1960s?) where on intersections without traffic lights, you were to STOP or GO based on the indication of a traffic light a block or more ahead of you.
Cross streets may have had to stop and look left or right and be guided by signal on adjoining blocks. I don't remember all that much of this weird system but do know it was in effect on Liberty - not sure of other streets. Maybe our pal from the old E225 house can add more.
