This has been happening all over town lately. There was an article in the Times about it recently. The old WALK/DON’T WALK signs were replaced 7-8 years ago by these LED pictograms. The new lights are reaching the end of their lifespan and have chosen to fail in this confusing manner.

indeed, these are all over manhattan, and in any other city, where jaywalking is a crime, i suppose this would be a problem, but not in manhattan!

This is probably an intentionsl failure mode.
Traffic lights are required by design specification to have multiple parallel control systems, i.e. if the green light control system malfunctions, there is a second validation mode which shares none of the original control system and can see that it’s trying to go green both ways. The conflict between the two modes forces a compromise failsafe (typicallly blinking red).
It is important that the failsafe mode be readily identifiable as a malfunction while at the same time not contributing to unnecessary danger.
Failure of the crosswalk mechanism probably defaults to this obviously incorrect state rather than fool a pedestrian into thinking it’s working.
