Semi-physical Simulation Platform of Intelligent Transportation Based on Micro Intelligent Vehicles

为了更真实地模拟现实环境中的人、车、路等交通要素及相关的交通设施,解决交通安全与拥堵等问题,提出一种缩微尺度下智能交通半实物仿真平台。介绍了半实物仿真平台的硬件组成和软件架构,进行车载系统、道路及路侧系统设计,详细说明此平台在车辆自主驾驶与多车交互驾驶、三维构图与定位和基于事件驱动的车联网集群混成控制3个方面的应用,并进行仿真。仿真结果表明:该平台能够使缩微智能车实现完全模拟真车在真实道路环境下的驾驶行为,为交通系统仿真与智能交通系统的研究提供了有益借鉴。

In order to truly simulate the people, vehicles, roads and related factors of traffic facilities in real environment, solve the problem of traffic safety and congestion, put forward a kind of miniature scales semi-physical simulation platform of intelligent transportation. Introduced hardware and software architecture of the platform, designed on-board system, road and roadside system, detailed applications in driving autonomously and driving by interacting with other cars, three-dimensional localization and mapping, and clustered hybrid control based on event driven in internet of vehicles, finally simulated all the applications. Simulation results show that the platform can make the micro intelligent vehicles simulate real car＇s driving behavior in the real road environment completely, and provide beneficial reference for the study of the traffic system and intelligent transportation simulation system.
