Study on Flow Direction Changing Method of Reversible Lanes on Urban Arterial Roadways in China

A flow direction changing method of reversible lanes on urban arterial roadways is presented based on signal timing, coil detectors and overhead changeable lane-use signals, hoping that the safety of lane changing maneuvers on reversible lanes will be improved and the transition of periodic flow direction change will be smoother. First, a new layout of signalized intersection approaches along reversible lanes is proposed. That is, lane function of signalized intersection approach doesn’t change with the direction of reversible lanes. Then, direction changing method of reversible lanes on urban arterial roadways from off-peak periods to peak periods is provided. The method can change direction of reversible lanes in certain signal cycles.
