The League of American Bicyclists is working on the problem of rumble strips.

Also go to
www.bikeleague.org and enter "rumble strip" in their site search engine. Thre is a lot of information there.
In my county rumble strips are cut the breadth of the lane from center line to the end of the shoulder. It forces a cyclist into the left lane (and oncoming traffic) to avoid them.
Road shoulders also have rumble strips. Sometimes there is enough room for a bicycle to ride the shoulder and avoid the strips, sometimes not.
Since the Illinois Supreme Court made a bone-headed decision in the case of Boub v. Wayne, there are strong disincentives for local authorities to make any accomodation for bicyclists on the roads in Illinois. I'm not hopeful about Illinois doing anything about rumble strips.
If you don't know about the Boub case, a cyclist was injured in 1988 when he rode onto a bridge that was under construction, but unmarked, as it was safe for cars to cross. In reaction to this decision, local authorities removed bike route signage in some counties, and throughout the state any appearance of accomodation of bicyclists on the roads has been scrupulously avoided.
The League of Illinois Bicyclists has cataloged some of the effects of the Boub case here:
