Abstract:
Maximum entropy method is adopted to obtain dynamic OD matrix, for it is the best one among the methods such as generalized least square method, maximum likelihood method and information minimizing method. Its mathematical model for estimating dynamic OD matrix is derived by using combinatorial theory. The implicit solutions of the model are derived by use of Lagrange multiplier. The actual solutions can only be obtained from iterative algorithm. The correctness of the iterative algorithm is strictly proved. Finally, the model and the algorithm are used to a simulation example and the traffic guidance system of Changshu city in Jiangsu Province in P. R. China. The results obtained are satisfactory.
