本研究以“常州市公交线网优化项目”为背景支持，首先给出一种能够容易、准确获得公交站点OD的方法——小票法；然后结合小票法的特点，利用Visual Basic程序语言进行编程处理，获得调查线路公交站点OD矩阵；最后利用沿线小区与公交站点的依附关系，提出分配权系数，建立小区与站点的分配权关系，从公交站点OD推导出公交出行OD矩阵.该推导模型是以小票法为基础，以公交站点OD矩阵为中间过渡参数，利用公交出行OD矩阵与公交站点OD的依附关系进行推导的.不需要大量的迭代计算，大大简化了推导过程，因此可以适用于大型城市公交网的OD估计问题.

Transit OD Matrix Estimation Based on Ticket Survey Method

This research takes "The Changzhou public transportation network optimization project" as the back-ground. A method named ticket survey method is proposed, from which the bus station OD is obtained easily and exactly. Then combined with the characteristic of the ticket survey method, the bus station OD is obtained by Visu-al Basic program language. Finally, by the attachment relationship between plots and bus stations, attraction weight coefficient is introduced and the relationship of assignment weight is established, then the transit OD matrix can be estimated from bus station OD. The model is based on the ticket survey method. It takes bus station OD as middle transition parameter and uses the relationship between plots and bus stations for estimation, instead of conducting the massive iterative computation. In this way, the new model may be applied to large-scale transportation network problems.
