摘　　要：以莞深高速改扩建工程为例,通过交通仿真软件建立交通仿真模型,对莞深高速的交通流特性进行分析,通过对比路段平均车速及各立交节点断面车流量的仿真值与实测值,验证了模型的有效性;在原模型的基础上建立交通分流模型,以道路饱和度为指标,对不同分流比例下的改扩建路段交通服务水平进行评价,分流比例在5%时,道路达到五级服务水平,分流比例在10%、15%、20%时,道路达到四级服务水平,分流比例25%、30%时,道路达到三级服务水平。Taking the reconstruction and expansion project of Dongguan-Shenzhen Expressway as an example,establish the traffic simulation model through the traffic simulation software,On the traffic flow characteristics of Dongguan-Shenzhen Expressway,By comparing the simulation value and measured value of the average speed of the section and the traffic flow of each interchange node,The effectiveness of the model is verified;Establish the traffic diversion model based on the original model,using the road saturation as an index,to evaluate the traffic service level of the rebuilt and expanded sections under different diversion proportions.The diversion proportion 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.
