Taking the reconstruction and expansion project of Dongguan-Shenzhen Expressway as an example,establish the traffic sim-ulation model through the traffic simulation software,On the traffic flow characteristics of Dongguan-Shenzhen Expressway,By compa-ring the simulation value and measured value of the average speed of the section and the traffic flow of each interchange node,The ef-fectiveness of the model is verified;Establish the traffic diversion model based on the original model,using the road saturation as an in-dex,to evaluate the traffic service level of the rebuilt and expanded sections under different diversion proportions.The diversion propor-tion is at 5%,and the road reaches the 5th service level.When the diversion proportion is 10%,15%and 20%,the road reaches the 4th service level.When the diversion ratio is 25%and 30%,the road reaches the 3rd service level.
