Abstract: This research takes “The Changzhou public transportation network optimization project” as the background. 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 Visual 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.
