摘要
OD矩阵是微观交通仿真、城市交通规划、管理和控制的重要基础数据。随着RFID技术在智能交通中的应用日益广泛,获得的交通数据越来越精确,为OD矩阵的获取提供数据上的便利。针对极大熵模型中没有给出分配矩阵获取的具体方法,提出基于RFID数据的分配矩阵获得方法,得到极大熵的改进模型,提高模型推算的精度。最后,以重庆市某路网作为研究对象,对该模型进行检验,实验结果证明该模型的可行性。
OD Matrix is an important basic data for micro traffic simulation, urban transport planning, management and control. With the increasing use of RFID technology in intelligent transportation, the traffic data obtained is more and more accurate, which provides the data convenience for the acquisition of OD matrix. Aiming at the specific method of allocating matrix in the maximum entropy model, proposes a method of obtaining matrix based on RFID data, and obtains an improved model of maximum entropy, which improves the accuracy of model estimation. Finally, applies the model to a road network in Chongqing, and tests the model. The experimental results show the feasibility of the model.
