GA-Transmodeler based time-dependent origin-destination estimation
基于GA-Transmodeler的动态OD矩阵估计方法*

This paper used a hybrid simulation-genetic algorithm method to accomplish off-line dynamic OD matrix estimation. The aim of simulation was to accomplish dynamic OD matrix thus OD-to-link flow proportion would be calculated while genetic algorithm was used to solve optimization function by crossover, mutation operator etc.The continuity of dynamic traffic flow and strong global convergence inherent in GA can be verified by the simulation cases.
