The results here are impressive, but the particular example they show in the last picture seems pretty dangerous, unless I'm misunderstanding. It seems like it places left-turning car traffic to the right of cyclist through-traffic, creating an opportunity for "left-hooks." Many jurisdictions use mixing zones instead: http://www.streetsblog.org/wp-content/uploads/2013/03/dc_mix...

(Unless there's a separate signal phase for the cyclist through-traffic, which is possible, but not that common in the US.)
