城市交通流分配的预测模型研究

在大量详实的资料的基础上．据一些具体的交通流特性．重点研究了一种动态多路径概率型交通流分配预测模型．并以此模型为基础研制了相应的交通流分配预测系统软件．在给出道路交通网的有关信息及其Ｏ－Ｄ出行矩阵的条件下，系统可输出一种最佳的交通流分配方案，它可为城市规划和重大交通工程建设提供有力的决策工具．

A Study of the Model for Urban Traffic Flow Assignment and Prediction

On the basis of a great deal of detailed material and some of the traffic flow characteristics, a kind of Dynamic Probabilistic Multi-Route Assignment model and an appropriate software system are mainly developed. Giving the roadway feature of the traffic network and its O-D trip matrix, an optimum scheme about traffic assignment can be obtained. It can provide a powerful scientific basis for decision making in urban planning and the construction of some major traffic projects.
