| 摘 要： | 为带延迟过境O-D流估计问题建立了概率分布约束的多元线性回归模型，设计了求解算法，利用这个模型分别估计出驶入车流量、过境车流量占路段车流量的百分比和流出车流量的大小，并且对模型进行了样本数据有误差时的抗差分析。结果发现当路段交通量数据有不超过3％的误差以及路段上不同去向交通流量的比例有较小摆动时，该模型总体结果能达到8％的相对误差精度，具有较好的抗干扰能力，是可行的。

| Abstract: | This paper gave a multi-linear recursive model with probability-constraints, and designed an algorithm following the viewpoint of the model for estimating the O-D matrix through a region with lagged traffics. The stability of the model was analyzed in the conditions of experimentation errors. The estimation error of the model is about 8%, when the error of traffic flow is less 3%, which shows that the model is feasible. 3 tabs, 2 figs, 8 refs. |
