模块化虚拟交通控制系统的交互技术研究

Interactive Techniques for Modularized Virtual Traffic Control System

虚拟交通控制系统是分布式虚拟汽车驾驶模拟器的重要组成部分,它由以下几种控制模块构成:红绿灯信号控制模块;警示灯信号的传感与响应控制模块;客体汽车的交通传感与控制模块;综合交通控制模块。在虚拟交通控制系统中,阈值的设定和检测的实施是2个关键技术,使用它们进行模块化编程,可以得到精确的交互控制效果。最后提供了对虚拟控制系统的应用实例。

Being an important component of distributed virtual automobile driving simulator, the virtual traffic control system is composed of the modules as follows： signal control module of traffic light; sensing and response module of alarm light; sensing and control module of other car in traffic system; integrated traffic control module. As two key techniques to get accurate interactive control in virtual traffic control system, threshold setting and test performing are presented in detail. Finally, examples of system applications are provided.
