摘要
引入了一种适用于描述局域路网出行车流分布的IO矩阵,提出了IO矩阵反推模型、求解算法(SQP法),并对模型解和提高模型推算精度的途径进行了讨论,最后给出了应用实例,显示了模型的优越性。
In this paper,the author introduces an IO matrix suitable for describing the distribution of traffic flow in local network, and puts forward an IO matrix estimation model and the algorithm of the model （SQP Method） is given too. Then the author gives a discussion of the result of the model and approaches used to improve the accurancy of the model. At last, an example is presented, and the advantage of this model is displayed accordingly.
