提出基于高速公路收费站进出口数据推算OD矩阵的一般方法。在缺乏初始OD矩阵的条件下,结合指数平滑法和无约束重力模型思想,通过VB编程反复迭代进行初始OD矩阵推算 利用组合模型预测高速公路各收费站出入口流量,通过弗雷特法进行OD分布推算。以沪宁高速公路为例证实此方法具有较高的精度。(Proposed highway toll station-based import and export data projections general OD matrix method. Lack of initial OD matrix conditions, combined with the exponential smoothing and unconstrained gravity model of thinking, through the VB Programming iterative initial OD Matrix Estimation flow of the use of a combination of model predictions highway toll station entrances and exits through Fratar Method for OD distribution projections. Shanghai-Nanjing Expressway, for example to confirm that this method has higher accuracy.)
