People can already be seen making use of the dedicated crossing time, riding and walking to and from the entrance to Golden Gate Park. Previously, crossing four-lane Stanyan meant they had to wait for cars to pass or risk stepping out in front of them, counting on drivers to yield (as they're legally required to).
The signals appear to change fairly frequently in coordination with the other signals along Stanyan, and they did not include push-activated pedestrian buttons. A bicycle sensor should also be in the ground, according to the project plans, though there aren't any markings for it yet.
