OD矩阵估计在区域交通分析中的应用

OD矩阵是交通运输规划的基础资料，是城市交通规划、控制与管理等工作的基础，而通过观测到的路段交通量和先验OD矩阵来估计未知OD矩阵，是一种效率高、周期短的OD矩阵获取技术。该文在深入研究国内外OD矩阵估计成果和实践经验基础上，提出了双层规划OD矩阵估计模型，并应用于区域交通分析中，取得了比较好的效果。

Application of OD Matrix Estimation in Analysis of Local Traffic

OD matrix is the fundamental data in transportation planning,and is the basis of the urban traffic planning,traffic control and management.It is a high-effective and short-cycle technique to estimate OD matrix according to the observed traffic flow of road section and the transcendental OD matrix to estimate the unknown OD matrix.Based on deeply studying the OD matrix estimating result and the practical experience at home and abroad,the article puts forward a bi-level program-ming model of OD matrix estimat...
