用路段交通量推算O－D量方法的进一步研究

Further Research on the Method of Estimating O-D Trip Distribution from Link Traffic Volume

本文在已有有关研究成果的基础上，对用路段交通量推算Ｏ－Ｄ量的方法做了进一步研究。对该方法所获解的唯一性和精度问题进行了深入的探讨，并在此基础上提出了改进的Ｏ－Ｄ量推算方法。使用改进后的方法，既可节约工作量又可一获得唯一的精确解。

Based on the outcome concerned, the method of estimating O-D trip distribution from link traffic volumes is studied in this paper. The problems about the uniqueness and the precision of solutions obtained in original methods are discussed, and the improved methods are put forward. Using the new methods, you can not only save time, but also obtain unique and precise solutions.
