As a transportation planner for a mid-size city about five years ago, I designed a bicycle transpo plan that called for placing bike lanes in the center of most two-way city streets. However, people raised hell and said it was a terrible idea. However, I felt that placing bike lanes in the center of the street would reinforce the centrality of bicycles in the local transportation system and force motorists to the margins of the road. To me, this felt right.
At the time this seemed like a noble idea. But in the end it did not work out so well. Has anyone else tried similarly visionary approaches?
