摘　　要：为了能更加准确地反映道路网络的交通流运行状态,针对小型路网结构,提出了利用满应力设计准则法的结构优化设计思想。同时建立了基于交叉口延误、饱和度的交通流分配模型,对模型参数进行了标定,并且采用连续平滑分配方法对路网进行了交通流分配。结果表明,所构建模型在交叉口运行状态优化的基础上得到了准确的交通流分配结果,较好地反映了路网流量的运行特点。In order to reflect the traffic state of road network more exactly, an optimum design method taking advantage of full stress design criterion for the small road network structure was proposed. Then the traffic flow assignment model was built based on the intersection delay and saturation, parameters were calibrated and the traffic flow was distributed by the continuous smooth distribution method. Results showed that the model obtained more accurate traffic assignment result based on optimized intersection of the traffic state, and reflected the feature of network flow more reasonably.
