Why settle for one roundabout about when you can have two? Segregation people, bikes and other modes of transportation shouldn’t be the default, partially because non-vehicle transportation always seems to get the short end of funding and design consideration, but sometimes it makes sense. This design from the Netherlands wouldn’t fit very many places, but perhaps there’s a place or two around St. Louis that could benefit from the idea:
^ The intersection before the bike/ped ring offered standard crossings for bikes and pedestrians. This doesn’t work well at highspeed traffic circles. The design above is meant to move traffic, not calm it. The light-controlled traffic circle is designed primarily to serve vehicular throughput.
{Norway has built something similar}
