Some scrambles allow "regular" ped crossings in the non scramble phase, others only allow ped crossings when all vehicle lights are red (not sure what Steveston uses)
>Denver, Colo. eliminated the diagonal aspect of its extensive downtown scramble crossing system — installed in 1952 — in 2011. The intersections still allow for pedestrians to cross both streets at the same time, but the diagonal walk signals have been removed.
That seems pointless. If all vehicular lights are red, why not allow the diagonal ped movement
