Research And Implementation Of Road Traffic Simulation System

With the rapid economic development,the number of cars owners in city has large numbers of increase, which brought a lot of traffic problems Such as:road congestion, mixing of traffic and traffic accidents, etc. At present, on the need for urban transportation,or the transformation of large-scale reconstruction,In order to ensure the economic development and urban expansion,that replanting of urban transport, new city roads and major city facilities are been needed,which include old City and existing roads, expansion, all of which need to research,analysis and forecast the flow rate and the characteristics of the flow rate. In addition, the growing contradiction between the demand for increasing road and the limited road investment makes mining existing road network line potential become a very important topic.With computer technology communications and information technology development, more and more brainpower means apply to intelligent traffic analysis and control, ITS is been gradually set up and develop.After several decades innovation, ITS research has been gradually applied in large-scale, ITS is playing a decisive role in traffic management. The traffic flow simulation is a importance part of the ITS system, it provides a source of intelligence-driver for ITS traffic guidance system. Traffic simulation is being more and more attentioned as an important multi-disciplinary integrated cross-disciplinary.Using "traffic simulation system" in analysis of urban road traffic can pre-testing "Urban Planning", the road to new-rebuild and changed,evaluating influence in new major facilities for the surrounding road traffic environment and evaluating effectiveness of "the strategy of ease traffic congestion".The main work of thesis is follows:First,in the existing characteristics of the simulation technology, elaborate the design and methods of simulation of system architecture. From the beginning as the main user, analysis the system of the services object, the logic function, the physical framework, revealed the necessity for traffic simulation.Second, comparative analysis of the existing simulation model, extraction of the simulation a more effective ideas of simulation. Analysis the current domestic situation in the traffic around the new ideas, divided into a number of the corresponding simulation model, analysis targeted the part of the problem.Third,structure a simulation system of corresponding function by anal ysis the existing simulation technology. It include the basis of system theor y, system architecture, and calculation model.Fourth,designing a traffic simulation framework software. Including th e target object class of the building, the design of the intelligent module, and finally introduction of the image programming. Images so that the e ffect of simulation is more intuitive, object-oriented programming methods also guaranteed maintenance program.Fifth, introduced in other major technology-related. Including the sharing of distributed data and the implementation method of the distributed information acquisition technology, and solutions of data-processing face a large number of data.Sixth, preliminary exploration at finite element method analysis play in part traffic management and analysis. This method make use of existing tools for finite element analysis of fluid to research trends the traffic flo w in the time-varying.
