it did help
b-c, here's what i got yesterday in an email from Nelson Chi, a City signals technician:
"I checked the signal operation and determined that longer green is needed for 29th Ave to accommodate the bike. The timing is adjusted and should work better now. Additionally, we were going to install an overhead sign "LEFT TURN YIELD TO ONCOMING TRAFFIC" for the southbound NW 29th Ave approach as result of traffic investigation. "
check it out. I don't know what happened to your original request, seems like they might have lost it somehow..?
