The left turn boxes (lower right of the graphic) would help keep bikes out of heavy traffic when turning. I'm guessing they might not be all that necessary in light traffic, and might not appeal to our more aggressive bicyclists anyhow.
I approve of the incremental approach to bicycling infrastructure in Cedar Rapids. It makes sense that before you stripe the entire city, or dump a vat of green paint, or buffer all the bike lanes, that you would do it in a small space first to see how it works. If only we'd done this with urban renewal, or interstate highways, or multipurpose sports stadiums... Which metrics to use when assessing the buffered bike lanes might be a tricky issue. Do we count bike riders on 3rd Av (and do we have a baseline)? Car-bike interactions? Public approval?
I first heard of protected bike lanes happening in Bogota, Colombia, as featured in the documentary "Urbanized." A spin around the Internet finds them installed or planned in Chicago, Columbus, Honolulu, Little Rock...
