Driving simulation systems play an important role in road safety research. However, there are still problems such as the difficulty of digital road modeling and low reduction of simulation scenes. The system uses Unreal Engine to develop simulation function modules, which can efficiently build a driving simulation scene based on the road geometry and the original traffic flows data. It uses pixel streaming technology to send video frames to the front-end page, sets the axis attribute mapping of the hardware device to support the analog drive external signal input, and stores the real-time driving behavior data onto the database. The online driving simulation information management and visualization system is lightweight, automated, and intelligent, which mainly realizes the functions of road automation modeling, human-vehicle-road-environment information management, lane-level real traffic flow scene restoration, online simulation driving and data visualization. The test results show that the system can run stably in the web end after deployment, making up for the shortcomings of the existing driving simulation system, and providing lightweight and efficient services for the experimental personnel.
