The new bus priority light northbound on 16th at U NW creates confusion for southbound 16th traffic that wants to turn left to go east on U. They get a green circle light and wait for northbound traffic to start moving (assuming they get the green light at the same time). Because of the bus priority signal, northbound traffic waits several seconds. This creates a situation where the southbound left turners give up on northbound traffic going and decide to make the left--right as northbound traffic gets the green light. It's a right-of-way conflict. Could be resolved by giving only the buses the signal and keeping southbound traffic stopped on red until the bus priority signal is over. That way, north and southbound traffic gets the green signal at the same time and there's less confusion and conflict.
