【 摘 要 】

In order to obtain the OD(Origin and Destination) matrix conveniently and accurately, the paper deals with the license plate data for time varying OD matrix between traffic crossroads by SPSS and Excel VBA, using vehicle trajectory tracking method to verify the reliability of the OD matrix. It provides an accurate and efficient OD investigation method for traffic planning and management department. Then, the obtained OD matrix is simulated by Vissim for dynamic traffic assignment study. It introduces the principle of dynamic traffic assignment based on Vissim, and combines the actual situation with Vissim platform to model actual road network and calibrate parameters. Finally, a network example result of the dynamic traffic assignment simulation is analyzed and evaluated. The overall delay of the overall network after DTA is reduced by 20%. The application of simulation results in road network evaluation and traffic planning management is also analyzed.
