The multiple threats to bicyclists, to pedestrians, and to motorists, are pervasive in the depicted scene. There is low visibility for turning motorists which in turn causes them to encroach on the right of way of other street users, including other motorists, bicyclists, and pedestrians.
This single image shows everything that is inefficient and dangerous to bicyclists and motorists about the intersection between north-south Green Street and diagonal Milwaukee Avenue in River West. Motorists should be physically blocked from entering or exiting Green Street at this point because of the danger inherent in the current intersection design. The block of Green Street south of Milwaukee Avenue is so insignificant to the driving network that no other design intervention should be implemented.
The situation depicted in this photograph demonstrates why the City should implement filtered permeability and close this entrance of the Green Street/Milwaukee Avenue intersection to motor vehicle movement. While motorists would be barred from entering or exiting Green Street here bicyclists would still have access to Green Street as part of the low-stress bicycling network of which Green Street is a part, between Milwaukee and Van Buren Street in Greektown.
I first wrote about this problematic intersection in June on Streetsblog Chicago and it remains an issue. One of the two motor vehicles ahead is blocking part of the bike lane while the second threatens to enter it. The bus on the left prevents the bicyclist in the bike lane from maneuvering around either vehicle. The photo below shows the situation from a different angle, that of the motorist wanting to turn left.
The vehicle operator on the left – a bus driver, in this case – has stopped the vehicle because they can occupy the intersection with the vehicle, or leave it open. Essentially, the bus driver has stopped to “let” the motorists on Green Street proceed across Milwaukee and further north into Green Street or turn left onto Milwaukee. Their movements would, again, put the bicyclist in danger, and put themselves and other motorists in danger because they are making nearly-blind turns into faster moving traffic.
The threats to the motorist are as limitless as the ones to the bicyclist (although the bicyclist will experience much greater injury if the threat is realized). As the motorist is paying attention to other motor vehicle traffic the bicyclist is coming down this bike lane – yep, I took the photograph – and is additionally obscured by the line of parked cars on the bicyclist’s right, and is in the shadow of the bus and the buildings. It’s like there’s a perfect storm of blind spots.
The quickest way to implement a system of filtered permeability and raise the significance and safety of the Green Street and intersecting Milwaukee Avenue blocks within the low-stress bicycling network would be to install a series of large planter boxes that prevent motorists from entering or exiting Green Street but allow bicyclists to filter through the planters.
And skip any traffic impact study. Not a single parking space will be lost or be made inaccessible with the implementation. A traffic study is not an experiment, but has practically been a foreboding document that has only ever said “things will be different”. (A good plenty of them have also suggested adding multiple $300,000 traffic signals.)
I read on Streetsblog USA recently about Pittsburgh’s new protected bike lanes:
“Instead of asking people to judge the unknown, the city’s leaders built something new and have proceded to let the public vet the idea once it’s already on the ground.”
Chicago maintains a Silver bike-friendly commenting ranking, yet my initial analysis shows that our metrics are below average among other Silver communities after which I’m led to believe we’re undeserving of the medal. Safety is a citizen’s number one concern when considering to use a bicycle for transportation and it will take an expansion of the low-stress bicycling network – currently not a priority – to deserve the current ranking or achieve anything higher.
This photograph depicts a nearly identical situation but from the perspective of the motorist on Green Street approaching Milwaukee Avenue. Two bicyclists have taken two routes around the motorist blocking the bike lane with their vehicle.
