I've always thought Chicago's encouragement of major arterials as bike routes as rather crazy. Buses, trucks, and 6-way intersections, on top of the usual rush of passenger cars, are incompatible with 200-pound blobs of metal and flesh. There is no overriding reason why the major arterials are where bicyclists' routes need to go. Instead, designating a side street, just 1 block over, into a major bicycle arterial would seem to be a better solution (assuming you could get past NIMBY issues, including loss of street parking). This could be repeated at regular intervals throughout the street grid. Bicyclists could still have access to arterials, but ideally it would be people whose origin/destination was there, while thru traffic would use the side streets.

Seattle plans side-street pathways for cyclists
By Mike Lindblom
Seattle Times transportation reporter
For several years, Seattle has painted bicycle lanes or icons on nearly all major streets, in hopes of encouraging people to ride.
Cycling has increased, but a lot of people remain ambivalent, including Jennifer Litowski of Ballard. She's comfortable riding some of the less-busy arterials. But when her 5-year-old son's bike is attached to the rear, she's not so nimble. The two detour to a calmer side street.
That's the idea behind
"greenways" — networks of residential roads outfitted with speed bumps, landscaped curbs that make portions of a street narrower, or stop signs to give cyclists and pedestrians priority over cars.
Seattle is building its first greenway across the Wallingford area this fall and will install signs for a future route on north Beacon Hill, while advocacy groups are suggesting routes in at least three other neighborhoods. Mayor Mike McGinn is proposing $150,000 for design and public outreach on a route in Rainier Valley next year.
