摘要
基于互动模式仿真,提出并开发了面向交通安全问题研究的、基于VR技术的人车路互动模式虚拟仿真系统,并阐述了系统的结构、软硬件组成和工作原理,讨论了系统实现中的若干关键技术,包括驾驶人交互操作信号数据采集技术、车辆动力学网络解算技术、基于Creator的虚拟场景建模技术、基于Vega的视景驱动技术、碰撞检测技术、三通道同步视景显示技术、基于Multi-Agent的车辆行为建模技术、仿真状态信息的动态显示技术等。实际的应用结果表明,该系统可以在道路设计阶段对设计方案进行量化的运营效果模拟和安全评价,从而达到优化设计方案、提高道路运营安全性的目的。
Based on features of interaction mode simulation, this paper analyzes the structure, software and hardware and the operation principle of VR-based driver-vehicle-road virtual simulation for traffic safety research, and discusses some key technologies for its implementation, including data collection of handling signal, network solution for vehicle dynamics, Creator-based virtual scene modeling, Vega-based vision rendering, collision detection, three-channel synchronous vision display, vehicle behavior modeling on the basis of Multi-Agent theory and dynamic display of the simulation information. Applications show that the operation simulation and safety evaluation will be carried out in design phase with the aid of the virtual simulation system, then the optimum design can be founded and road safety can be improved. 8 figs, 12 refs.
