Estimated OD Matrix based on Multipath Choice Model by using Urban Traffic Flow

The OD matrix is the basis of traffic planning. The traditional OD survey method is low in economic efficiency and accuracy, but the OD matrix estimation can derive the OD matrix from the urban road observation flow. This paper mainly introduces the estimation method based on multipath choice model in Transcad software. Taking Huangshi City as an example, first the authors constructed different types of initial matrices, and used simulation software to obtain the inverse matrix. The relative error is used to verify the accuracy of the results. The results show that the initial matrix structure is more similar to the actual one, the backstepping result is more accurate, and the inverse OD matrix can meet the accuracy requirements of traffic planning.
