The Design And Implementation Of Integrated Passenger Hub Function And Structure Of Numerical Experiment System Three-Dimensional Module

Simulation is an effective way to research traffic problem. At present, the traffic simulation softwares have two shortages. The one is that the softwares can not describe the height information because they are two-dimensional, the other is that the softwares can not handle the intelligent objects because they use OOP as the main method of simulation.The ministry of science and technology project topics from the " integrated passenger hub function and structure of numerical experiment system." Through the various types of traffic flow within the integrated hub (passenger flow, a broad range of flow) simulation analysis, (1) evaluation hub layout of the various facilities within a reasonable degree (2) hub for the correct analysis from the drop-dredging factors (hub facilities within a fixed size, number, location, type, etc.), provide a theoretical basis and supporting decision-making tools, (3) visual reflect the bottleneck of the integrated hub, hub to facilitate the design optimization, perfect."Integrated passenger hub function and structure of numerical experiment system." is a powerful city passenger transport hub in the simulation and analysis of experimental platform, including simulation modeling, two-dimensional simulation, and 3D analysis of the four major functional simulation. This system features a forward-looking design, absorb and learn from the advanced international passenger traffic flow simulation system with the advantages of multi-agent technology, the pedestrian and vehicle traffic, and other entities conduct realistic simulation, convenient control and to facilitate flexible analysis and experimental. This system applies to all the city's rail, subway stations, bus terminal and from their integrated transport hub of the traffic behavior simulation, design and evaluation of the programme of experiments. Author of the software system is mainly responsible for the design of three-dimensional simulation module to achieve the related work. Integrated passenger hub function and structure of numerical experiment on the whole system based on two-dimensional, and the analysis have been established in the experiment on the basis of two-dimensional simulation. 3D simulation system is a supplement to the system as a whole and sublimation, is to display to users better simulation results. 3D simulation system is a separate module, both the modeling and simulation functions, but does not have the analysis function.Using virtual reality simulation of the actual urban traffic urban transport means, in a realistic 3D scenes in the urban traffic control in a variety of different ways to observe the view, through a change of scene for the eventual establishment of an effective city traffic control and management to provide effective basis. Virtual Reality urban transport in the past people adapt to change computer environment, people can deal with the environment as day-to-day things like urban traffic exchange with the computer to be more intuitive and transparent use of the corresponding sensory devices to operate, find the best urban traffic control and management data.Direct3D constitutes one of the emerging APIs from Microsoft Corporation, which used for disposing 3D drawing and accelerating displaying. These APIs provide objects and functions for developing real-time, high-performance applications on the windows platform. 3D module in achieving the details, the use of animation technology to human bones or movement of vehicles in the simulation, the more vivid the use of skin technology that enables more lifelike scenes; mixed use vertex Index improved graphics smoothness and efficiency of system operation; use advertising board technology, the realization of a three-dimensional picture of the display; use MSXML controls for reading and writing XML data. It brings forward a new Direct3D approach, conducts systematic and in-depth analysis for the specific construction of system and relevant technical problems about control-model and data - outputting . By using Visual Studio 2005 and DirectX SDK, the realistic and real time simulation system is carried out, according to the demand of the system. The study has realistic and wide application value for low cast graphic simulation. and finally provides original insights.
