 In 2006 , the New York State Department of Transportation ( NYSDOT ) converted NY 376 's intersections with the main gate of Vassar College and College Avenue into roundabouts . Both of the roundabouts replaced traffic lights . A traffic signal used to control traffic for a pedestrian crosswalk was also removed as part of their construction . Another roundabout was constructed in 2008 at Fulton and Collegeview Avenues . NYSDOT has called the installation of roundabouts a success , stating that it has significantly calmed traffic , decreased congestion and increased traffic flow .
