Abstract:

在车路协同系统仿真的基础上,以局部交通网络的实时交通仿真为例,建立了车路协同系统视景仿真模型库,确立了视景仿真系统的框架体系结构。将视景仿真集成为整个仿真系统的一个联邦成员,建立了车车信息交互、车路信息交互的典型视景仿真功能模型。使用LOD模型简化技术对视景仿真功能模型进行分解,生成了5个不同精细程度的LOD模型。采用DOF、LOD、Switch功能化节点,从节点结构上优化了典型应用场景中的交叉口信号灯、车辆运动等相关模型,建立了一套类似模型几何形状的层级节点结构。构建了车路协同系统可视化视景仿真平台,包括HLA/RTI信息交互与控制模块、车路协同数据处理模块、信息交互模块、模型引导控制模块、视角动态切换模块与模型状态参数动态显示模块。采用建模优化相关技术,对典型交通场景进行了视景仿真。仿真结果表明通过LOD模型简化技术,模型简化率最高可达95.5%,内存占用减少86.3%;通过视景仿真方法的使用,提高了渲染效率与系统仿真效率,车路协同典型交通场景验证了仿真方法的可行性。
