[Abstract]:At present, the advanced traffic information service system, which takes the integration of traffic control and guidance as the core, has been proved to be an effective way to solve the urban travel difficulties. And the dynamic traffic assignment theory also provides the direction for the intelligent transportation system to adopt the guidance strategy and the signal control strategy. It is the future trend to apply the three to the urban traffic. In this paper, the dynamic traffic assignment theory based on simulation is constructed by using TransModeler to construct the urban micro simulation platform. The dynamic traffic assignment of traffic guidance and traffic control system decision making is applied to the micro simulation platform by adopting the idea of signal control adaptive induction and partition. Based on the related theories of traffic guidance and signal control, the implementation framework of urban guidance and signal control system based on dynamic traffic assignment for large-scale road networks is proposed. In order to realize the system framework, the key technologies involved in the implementation of the urban guidance and signal control system based on dynamic traffic assignment are deeply studied. These include:. The micro simulation platform construction theory, the global initial optimization theory of road network signal control, the dynamic traffic assignment based on simulation, the integration technology of signal control and induction, the method of obtaining discrete dynamic OD, etc. Finally, taking Zhangdian District Road Network in Zibo City as an example, the corresponding micro-simulation platform is established. The guidance and signal control system based on dynamic traffic assignment is applied to the platform, and the system evaluation system is adopted. It is verified that this system plays an important role in reasonably distributing urban traffic flow, alleviating urban congestion, facilitating people to travel and improving the efficiency of road network operation.
