Traffic Flow Prediction and Bi-level Programming Model for Estimating Origin Destination(OD) 交通流预测与OD估计双层规划模型
In this paper, based on the layout of existing railway network, flows of Origin Destination(OD), and levels of existing lines reconstruct, we established the mathematics model of limited investment. 基于现有铁路路网的布局,根据各点对之间O-D流的要求和各路段的改造水平,在有限投资额约束的情况下,建立了相应的数学模型。
In the numeral results, estimation values of origin destination demands and the link traffic flows can be obtained simultaneously from the model and algorithms. 试验结果表明,本文所给的模型和算法不仅能较好地给出OD需求的估计值,而且同时还给出了各模式路段流量的估计值。
In highway network plan, we adopted multi-route method combined with OD ( origin destination survey ) method to predict traffic capacity. 本公路网规划中,采用多途径与OD分析相结合的方法进行交通量预测。
