Video by Brandon Gobel
Brandon Gobel sent us this video showing dozens – I count 27 – of people bicycling southeast on Milwaukee Avenue towards the five-way intersection with Kinzie Street and Desplaines Street. There were 13 motorized vehicles in the same signal cycle.
You'll notice about half are changing lanes from the conventional curbside bike lane to the single travel lane so they can merge to the bike left-turn lane ahead.
The view from the opposite direction, looking southeast at the intersection of Kinzie Street, Desplaines Street, and Milwaukee Avenue.
Unfortunately, because of signal timings at the intersection they just left (Hubbard/Milwaukee) uncoordinated with their destination intersection, the first in the group won't be rewarded with a green light for their tricky uphill lane change maneuver, and will need to stop at the red light, while those in the back of this group will likely get a slim chance at moving through a green light (the green light is only 12 seconds long).
I've heard from several people who cycle here, Gobel included, that changing lanes from the curbside bike lane in a dark viaduct to the travel lane in order to reach the bike left-turn lane ahead can be very stressful.
Another issue with the light, but not related to this video, is that the light cycle for people who want to cycle from Milwaukee to Kinzie (making a slight left to go eastbound) is designed such that if you enter the intersection at the end of the green phase, you will be in the intersection for the entire yellow phase, part of the red phase, and then the beginning of green phase for the cross direction. I explored this – long intersections – on my blog, Steven Can Plan.
