Columbia, Missouri is a small city with a population of 100,000 that is not densely populated and has hills, weather extremes, and urban sprawl barriers. The city aims to create an integrated bike and pedestrian system by adding bike lanes wherever possible and innovating ideas from other cities. In 2010, the system included 30 miles of shared use paths, 50 miles of bike lanes on streets, and 30 miles of shared lane markings. The city has experimented with several innovations for bike and pedestrian infrastructure including on-street wayfinding, loop detector markings, buffered bike lanes, and advisory bike lanes in the center of low-traffic streets.
