Abstract: Under the influence of various factors the initial green time and vehicles arrivals obey probability distribu -tion properties .This research proposes a new intersection actuated control model for optimizing maximum green time by using average delay ,number of stops ,and queue length as evaluation indicators .By using the Vissim simulation soft-ware ,the model is compared with the traditional actuated control models .Simulation results show that the proposed algo-rithm shows better improvement under different vehicle saturation levels ,where the traditional models can only have lim-ited success .
