Also hard to solve--just extending the signal times won't really fly. Although...if you were willing to spend the money, you can probably program some kind of AI to monitor a video stream of the crosswalk and not let the signal change until any slow-moving stragglers are done. This could be prone to abuse, and there are some easy strategies that can be compensated for, but it's hard to differentiate from an elderly person, who, say, fell, and someone deliberately laying in the crosswalk.
