| 摘 要： | 首先建立了城市公共交通客运量的灰色模型,提出用自回归平稳模型来修正不满足从某一时刻开始连续为相同符号这一条件的残差序列,建立了修正灰色模型.最后,用实际数据进行了检验,得到的数据比原有模型的精度有明显提高,证明了模型的正确性.

| Abstract: | A grey model of passenger volume of city public traffic is built up firstly, then an autoregressive model to improve the residual series that isn't the same symbol from a certain time is brought forward. Secondly, the modified grey model is established. At last, using practical data to check up the model, we find that the precision has increased, and the model is right. |
