OD矩阵是智能交通的重要研究领域之一,是微观交通仿真、城市交通规划、管理和控制等的关键数据。本文将微观交通仿真与交通信号机监控系统相结合,提出一种基于极大熵法的动态OD估计算法,分析路段交通流的动态变化,为提高OD估计的精度,给出一种历史OD矩阵的递推方法,仿真结果表明本文方法是有效、可行的。
OD matrix is one of the important research fields of intelligent transportation. It is the key data of micro traffic simulation, urban traffic planning, management and control. In this paper, the micro-traffic simulation and traffic signal monitoring system are combined to propose a dynamic OD estimation algorithm based on maximum entropy method to analyze the dynamic changes of road traffic flow. In order to improve the accuracy of OD estimation, a historical OD matrix Recursive method, the simulation results show that this method is effective and feasible.
