Abstract: Based on the goodness-of-fit between dynamic road resistance function in dynamic traffic assignment and the current situation of the actual vehicle travel time , the original traffic wave model was improved by the relationship model relating road Greenshield speed-density. And the improved dynamic road resistance function was then established to adapt the dynamic traffic assignment. A case study was performed to validate this function by TransModeler simulation The results show that the improved function is practicable. The calculated value of the improved dynamic road impedance function is closer to the simulation results compared with the original function.

Key words: traffic wave, TransModeler, dynamic assignment, dynamic road resistance functions, average travel time

摘要： 以动态交通分配中的动态路阻函数与现状实际车辆行程时间的拟合度为基础，运用道路Greenshield 速-密关 系模型对原有交通波模型进行改进，建立了更适应于动态交通分配的改进动态路阻函数。通过TransModeler仿真 进行实例验证，结果表明:改进动态路阻函数可行，改进动态路阻函数计算值比原函数计算值更接近仿真结果
