A way out of the city’s rotary from hell?
The Boston Globe - 07/25/2015
Peter Furth, a professor at Northeastern University who studies traffic, said the old-fashioned design is partly to blame. There are supposed to be two lanes that run around the entire circle, not that anyone would know that, because there are no painted lane markers. The circle also includes an impromptu third lane for drivers who travel only one exit, which others try to exploit as they enter the fray, cutting off vehicles already in the rotary, who have the right of way.
“The older rotary design is based on the assumption that traffic would be light, and that there would always be gaps so that you could fly in and out,” Furth said.
