为了快速有效地对信号控制系统的控制效果做出评价,提出多路口交通信号控制硬件在环实时仿真系统开发。通过采用硬件在环的方法,建立基于交通微观仿真软件的城市多路口交通信号控制仿真场景,与外部的信号控制器建立硬件在环系统,实现仿真场景与交通信号控制器的实时信息交互,形成符合实际交通控制情景的仿真环境,从而对多路口的交通信号控制系统的控制效果进行评估。对北京市中关村东路建模仿真,仿真结果表明硬件在环仿真系统不仅可以评价不同型号的信号控制器的控制效果,而且可以快速有效地对多路口的信号控制效果做出评价。
In order to evaluate the control effect of signal control system quickly and effectively, the development of real-time simulation system of hardware in-loop control of traffic signal with multiple junctions is proposed. By using the method of hardware in the loop, a simulation scene of traffic signal control in urban multi-intersection based on traffic micro-simulation software is established, and a hardware-in-the-loop system is established with an external signal controller to realize the real-time information interaction between the simulation scenario and the traffic signal controller. In line with the actual traffic control scenarios of the simulation environment, thus multi-intersection traffic signal control system to evaluate the control effect. The simulation results show that the hardware-in-the-loop simulation system not only can evaluate the control effects of different types of signal controllers, but also can evaluate the signal control effect of multiple junctions quickly and effectively.
