A system of traffic lanes and signal means for reducing the number of signal phases per repeating cycle of a signalized traffic intersection at grade. Opposed turn center lanes ( 24 ) adjoin opposed turn bypass lanes ( 20 ) that are substantially parallel and adjacent to the near side of the destination roadway approach lanes ( 10 ). Opposed turn bypass lanes ( 20 ) intersect with destination roadway approach lanes ( 10 ) and departure lanes ( 32 ) each respectively containing signal means ( 22 ) ( 12 ) ( 30 ). The system generally permits opposed turn traffic to proceed through the intersection in two phases. Phase phi 1 provides opposed turn vehicles on the center lanes ( 24 ) to proceed onto the bypass lanes ( 20 ) during the destination roadway thru phase. Phase phi 2 provides vehicles on the bypass lanes to proceed onto the departure lanes ( 32 ) of the destination roadway during the origination roadway thru phase. This system accommodates left-handed or right-handed driving conventions.
