| has gloss | eng: The Bowtie is an alternative to the Michigan left format that uses roundabouts on the cross street. Left turns are prohibited at the main intersection, which therefore requires only a two-phase signal. Vehicles yield upon entry to the roundabout, but if the roundabout has only two entrances, the entry from the main intersection does not have to yield. The roundabout diameter, including the center island and circulating roadway, varies from 90 feet to 300 feet depending on the speed of traffic on the approaches, the volume of traffic served, the number of approaches, and the design vehicle. |
