Abstract： As a significant method for bus data visualization, OD matrix provides basic data for evaluating and optimizing bus system. Based on cloud computing， a model for estimating OD matrix was proposed to analyze the data after filtering, preprocessing, changing and mining. To generate an OD matrix with high accuracy, a model was also provided for estimating OD matrix by comparing and combining data via analyzing data of each holding IC card holder and generating gravities for each station. The testing results of real bus data show that the proposed model can estimate debarking data accurately to match real OD matrix well.
