I am trying to understand the new bike signals on first street in NoMA. The bike signal goes green at the same time as the walk signal but then turns red significantly before the walk signal ends and the green light ends. My only guess is that the idea is for the bike signal to go red to allow cars to turn across the bike lane but if the walk signal is still going then, it is still not safe for cars to turn. For instance, if I dismount my bike and walk it can I still cross? Are these signals just horribly set up? Or is there something I am missing?
