Research on the model and algorithm of origin-destination matrix estimation for urban rail transit

Abstract

OD matrix is the basic data in researches of urban rail transit system. OD matrix estimation is an important way to obtain the OD matrix, especially for the rail transit. So the OD estimation model for urban rail transit is researched in this paper, and the main content of the article include the following aspects. First, we selected the probability model to calculate the probability of the station numbers travelled by passengers. Then, we revised the probability method according to the passenger flow characteristics and built an OD estimation model based on this method. Finally, we studied the algorithm and the process of the estimation method. At the same time, the example of Shanghai rail transit line 1 demonstrated the rationality and feasibility of this OD estimation model.
