Urban Microscopic Traffic Simulation System Research

At present, the computer simulation is a kind of main method in scientific research and solving the real-life problem difficult to implement. Traffic simulation is an important application of technology of computer simulation in the field of traffic engineering. People began to utilize the computer to imitate the traffic behaviors, the research of traffic simulation, especially the research of microscopic traffic simulation, has made enormous progress, urging by of development of traffic theory, computer hardware and software engineering, basic traffic facility and social demand. Computer hardware and software engineering, especially for software programming and modeling technology, are developed rapidly during recent decades. Its rapid development is playing an essential role to the development of traffic simulation.The main contents and contributions can be summed up as follows:1. The microscopic traffic simulation modeling and the design of the relevant simulation software are the research focus in this paper. On the basis of understanding and studying the domestic and international research of microscopic traffic simulation, summarized the present situation and existing deficiency in the research field of microscopic traffic simulation.2. Build a framework of the microscopic traffic simulation modeling. It constituted by traffic demand model, road network model, vehicle running model, intersection conflict model, vehicle running track model, system evaluation model.Describe the vehicle running model and intersection conflict model on emphasis,including with vehicle-following model and the achievements researched on this model.3. The solving methods of some key technologic problem in the designee of microscopic traffic simulation software were decribed.In the end, the thesis concludes with a summary and perspectives of the future research of the field.
