Only the accurate traffic flow OD can ensure the scientific operation plans and rational utilization of the staffs and vehicles. To improve the estimation precision, the paper put forward an idea that traffic flow OD was affected by trip characteristics, land use and transferring function around the bus stops. A K-S test was adopted to analyze the station numbers of the public trip and the result showed that it follows the poisson distribution. Considering the passengers’ number boarding and alighting the stop, an OD estimation based on trip characteristics was presented; The paper also proposed the attracting coefficients, attracting weights and got the OD matrix estimation based on land use; It put forward that the stop significa
