Afternoon in the Intersection of Equality
and Safety
Intersection Design Workshop Demonstrates
New Level of Cooperation
by David Callahan
So, a blind man, a bicyclist, a motorist and a wheelchair rider
arrive at the corner of Clark and LaSalle streets at the same time
...
Fast forward to the punchline: They all encounter hazards, and
they work together to find solutions.
At the March 31 Soles
and Spokes Real Intersection Design Workshop, sponsored by the
Chicago Area Transportation
Study as part of the Chicagoland
Bicycle Federation Healthy Streets Conference, nearly 45 participants
did just that. Dividing into teams representing limited mobility,
the visually impaired, motorists, bicyclists, pedestrians, mass
transit and streetscaping, the workshop sought to make-over this
major intersection with equal accommodation to all, whether they
arrive in an SUV or a wheelchair.
The only rule was, make the intersection safe, and exclude no users.
Participants were given a crash course in design, led by intersection
design expert Michael King of the New York City consulting firm,
Nelson/Nygaard.
Then, they split into teams and, independently of one another, evaluated
the intersection from the perspective of their assigned user-groups.
Finally, they reported their recommendations to optimize access
and safety for their respective constituencies.
For the wheelchair group, this included relocating a fireplug from
the center of a sidewalk, fixing the slopes to the crosswalks and
increasing the crossing signal times. For the motorists, making
sure that the lanes of LaSalle line up on each side of the intersection
was a priority. The bicyclists asked for little more than a lane
of their own and a “bike box,” or advanced stop bar,
to help make the left turn from LaSalle onto north bound Clark.
What would seem to be a recipe for conflict, became instead a study
in how groups protecting their own interests can find common ground
when the guiding standards are fairness and safety.
For example, each group sought to tame the "soft" right
turn from southbound Clark to southbound LaSalle. Tightening the
other corners served the interests of both pedestrians and motorists,
who sought to moderate speed in the intersection.
None of the design recommendations contradicted the others in any
substantive way. The six teams presented practical, doable solutions,
which were forwarded to the city of Chicago for review.
CBF Planning Director Nick Jackson said CBF hopes to develop partnerships
so this process can be used to remedy other dangerous interesections.
