Abstract: Aiming at the difficulty of current traffic control strategies simulation, this paper proposes simu-lation system architecture of traffic control strategies hardware-in-the-loop after analyzing the principle of hardware-in-the-loop simulation. The simulation control software as the core of the whole system is responsible for simulation process control and management; the traffic controller completes traffic control strategies release and induction control; the microscopic simulation software completes the simulation and evaluation of traffic control strategies; the signal converter achieves digital signal to analog signal conversion and allows the communication between the traffic controller and microscopic simulation software. Finally, the simulation control software is developed and simulation system of traffic control strategies hardware-in-the-loop is built based on HST-3000 traffic controller and VISSIM microscopic simulation software. Experiments show that the system can achieve effective simulation of the traffic control strategies and verify the effectiveness of the simulation system.
