Abstract: Urban regional traffic signal control and optimization is an important means to alleviate urban traffic congestion, and effectiveness evaluation is an important part of traffic signal optimization. The traditional traffic simulation software is generally evaluated by the built-in signal control module, which is out of touch with the actual signal control system and has low evaluation accuracy. In order to connect simulation software with signal control system and improve evaluation effectiveness, an urban road network traffic control platform based on the hardware-in-loop simulation was proposed. The logical framework, function architecture, center system and controller interface etc. of hardware and software modules of the platform were designed. The arterial coordination control algorithm and regional cooperative control algorithm were integrated. And the hardware-in-loop simulation control function was verified through the communication test. The case study analysis shows that the platform of hardware-in-the-loop simulation builds the bridge of the traffic simulation software and the traffic signal control system, and it can effectively evaluate the traffic control effect of the road network. Based on the proposed platform, the effectiveness evaluation of the regional traffic signal control, the improvement for control algorithms and signal optimization can be carried out.
