In this paper, the estimation of origin-destination (OD) matrices for public traffic passenger flow is given. As the basis of transit scheduling, more accurate OD matrices mean more scientific operations and more rational utilization of staff and vehicles. In order to improve the estimation precision, characteristics of a passenger's trip, land use around bus stops, and transferring function are considered. Kolmogorov-Smirnov (K-S) Test method is adopted to analyze the trip stops. The result shows that it follows a Poisson distribution. According to passengers boarding and alighting, the OD estimation based on the trip's character is present. Attracting coefficient and weight are employed to estimate the OD matrices based on the land use around the stops. The stop significant coefficient, which relates to the route number of stations as starting, ending and midway, is also proposed to estimate the OD matrices based on transferring function. Analytic hierarchy process (AHP) is used to combine these three factors, and the last OD matrices are gained. Real data are applied to test the estimation methodology. Good agreement between predicted and observed matrices is found, and the results prove that the method is feasible to heighten accuracy.
