Simulation System for Optimizing Urban Traffic Network Based on Multi-scale Fusion

The research on Urban traffic simulation is more widely, But there are some problems, For example, the traffic system in the spatial scale is from microscopic to macroscopic highly integrated. In the time scale is from the second grade to the height of continuous integration. Simulation and objective traffic system complexity determines that any single scale are difficult to be better traffic phenomena. On this basis, the simulation system was proposed based on multi-scale fusion, from the macro, meso, micro in three dimensions using the corresponding algorithm, and carries on the design to the system. Finally, Based on multiscale fusion of urban traffic network optimization simulation system has carried on the experiment. Through the example of Nanjing Fujian road and Traffic Signal Priority of the three arches to analyze network simulation experiment. The experiment proves that the system is practical and reliable.
