On-line Simulation System of Urban Road Traffic Signal Control Based on Scene Driven

In this paper we present a scene-driven urban road traffic control online simulation system called SD-UTCS. With this system, managers and researchers can realize the construction and simulation of various types of traffic scenarios, the rapid development and optimization of new control strategies, and the application of effective control strategies to actual traffic management. Firstly, the parallel system concept is adopted to realize the deep integration of the real-time traffic control system and the real-time simulation system, and the visual hardware and software in the loop system is used for display. Secondly, the virtual scene base engine and the strategy agent engine are put forward in the system design. By designing a common control strategy API to achieve data and control strategy separation, help researchers focus on the control algorithm itself without paying attention to the detection data and basic data, and use the detection data and GIS data to complete the automatic calibration of simulation parameters to ensure traffic simulation accuracy. Finally, in order to verify the real-time and stability of the simulation system, simulations were carried out using different scale road networks in Shunyi District of Beijing and Weifang City of Shandong Province, which proved the advantages of the simulation subsystem in performance and simulation scale.
