NCHRP Project 03-100: Evaluating the Performance of Corridors with Roundabouts
KAI completed NCHRP Project 03-100: Evaluating the Performance of Corridors with Roundabouts, which includes field evaluations of nine roundabout corridors, and provides performance measurements and evaluation methods to comprehensively evaluate the performance of a series of roundabouts in corridors. The evaluation method is compatible with the framework in the Urban Streets chapter of the 2010 Highway Capacity Manual. The project also includes a corridor comparison framework that practitioners can use to objectively compare the performance of a corridor using roundabouts, traffic signals, and/or stop-controlled intersections. The work is published as NCHRP Report 772.
