London has succeeded in upping bike traffic by 70 percent:
“The city of London just announced that bike traffic is up 70% on two major thoroughfares in London proper and they are crediting it all to the opening of two bike superhighways last July. … The two open superhighways are just the beginning — 10 more will be installed in the coming years.”
When Chicago was asking its own residents for ideas on how to do the same, my suggestion was something like what London is doing.
Optimally, costs aside, I’d love raised bike trails, similar to but more extensive than the El tracks, to get bikers off the road altogether.
