Sitzman said he hasn’t heard of any accidents resulting from the roundabouts.
Carmel Mayor James Brainard said his city has reduced the injury accident rate by 80 percent when contrasted with traffic lights and has reduced all accidents by 40 percent.
Brainard said the roundabouts save fuel because motorists are not stopped at lights. While roundabouts cost more to build, the savings in the cost of traffic signals, their operation and maintenance make up the difference, Brainard said on the city’s website.
Carmel has bike lanes and a number of bike paths. The city also has an alternative transportation coordinator, David Littlejohn. In 2006, Carmel earned a bronze designation for being bicycle friendly — an honor Norman also has earned — from the League of American Bicyclists. The city has been expanding and promoting bicycling in the community since with 125 miles of multi-use paths and greenways.
The city also has about 100 miles of bikeway which connects multi-use paths with local, low-volume streets. Some routes are recreational loops, but the express routes facilitate transportation throughout the city.
Bike parking is available at hundreds of bike racks in Carmel — new businesses are required to put in bike parking. Large events feature bike corrals where people can check their bikes and know they will be safe until the event is over.
While roundabouts for Lindsey Street are still being debated, Carmel may have other useful ideas to inspire Norman as it plans a multi-modal future that includes bicycles.
