From the aspect of reducing the vehicle emission in urban intersection, according to the ef?fect of driving direction and condition on vehicle emission, vehicle emission comprehensive model, in?cluding vehicle states of complete parking, incomplete parking and no parking under the condition of go?ing straight and turning left, was established. Combined with vehicle delay, a optimization control model was proposed taking delay and emission as optimization objects and equal saturation optimization decom?position algorithm as solving method of cycle length. VISSIM simulation software was utilized to simu?late, compare, and analyze the original timing, the Webster optimization timing and the comprehensive index optimization timing. Simulation result shows that the proposed method can obviously decrease the total delay, total emission and comprehensive index PI, and it has obvious optimization effect.
