| Abstract: | This article establish a forecast model of passenger volume in the public transportation by combine with gray system estimate and the BP networks model. The network model can organize and study itself, according to different study error, continuously adjust the study rate, and accelerate refrain process, expel influence of the data sample. With traditional forecast method compare, the accuracy of this model forecast result is higher. |
