Abstract: By taking phase effective green light time，saturation，and reverse variable lane length as constraints，a control model of double target functions as minimum delay control time at intersection and maximum traffic capacity at intersections was established.With application of the double target optimization NSGA-Ⅱ algorithm，target functions were calculated，and the solution of signal timing of relative superiority of traffic capacity was achieved so as to achieve the goal of improvement of control efficiency at intersections.Using a Chongqing intersection as an example，the NSGA-Ⅱ algorithm was used to solve the signal timing plan of the reverse variable lane.Compared with the existing signal timing plan，the optimized signal timing plan of the reverse variable lane can improve intersection capacity and reduce control delay.
