Development trend of driving simulator
1. Combined with sensor network technology, traffic simulation of actual road network is carried out. With the gradual promotion and improvement of the sensor network of the traffic system, the virtual driving system can be combined with the actual road system in the future, such as the 3D map network developed by Google and so on, aiming at the actual traffic environment of the city, train the driver's driving skills, be familiar with the road signs, and avoid the occurrence of novice unfamiliar with the road situation. Combined with traffic sensor network, such as speed limit monitor, red light running monitor, road communication network, etc., add the actual road traffic flow and pedestrians, increase the experience of red light running at intersections and virtual traffic police inspection and fine and other interactive exercises, make drivers familiar with traffic safety regulations and urban traffic environment, and better improve the safety awareness of drivers.
2. Establish a database of simulated driving behaviors of different drivers. It is one of the important means to reduce traffic accidents to establish the evaluation system of drivers' psychological quality in emergency. In an emergency, the driver's psychological reaction and behavior play a decisive role in whether a traffic accident occurs. The driver simulator can be used to set different training scenarios and dangerous road traffic conditions, such as sudden accidents, abnormal weather, physical discomfort, etc., and different types of drivers (different gender, age, driving age, etc.) can drive the vehicle, measure the driver's psychological and physiological reactions, record and analyze such data, and establish a database of driving characteristics for different types of drivers to guide the driver's driving behavior.
3. Realize the rapid three-dimensional reconstruction of the scene of major road traffic accidents. Using computer graphics technology and wireless information transmission technology, it is possible to quickly collect and transmit information about major traffic accidents to the public security traffic police command center. Combining vehicle characteristics, road environment, and driver databases, 3D imaging technology is used to quickly reproduce the scene of traffic accidents. Combining the training files of drivers on a driving simulator is conducive to the analysis and detection of traffic accidents by the public security system.
4. Establish a unified software development specification and system management platform. With the development of driving simulation technology, it is necessary to develop a unified software development specification to provide a standard development environment for the products of various manufacturers, so as to improve the development efficiency and promote the orderly development of the industry. Establish a unified system management platform, establish a complete urban three-dimensional map and model database, facilitate the daily update and maintenance of vehicle performance, traffic conditions, road conditions, signal timing and other data, and facilitate the object-oriented secondary development.
5. Combined with Intelligent Transportation System (ITS). Intelligent transportation system includes intelligent vehicle safety technology and other fields, which can well improve the current situation of traffic congestion and frequent occurrence of major events. However, the investment in intelligent transportation system is large and the planning is complex, involving urban planning, road and bridge construction and other major projects. Combining the virtual reality technology of driving simulator and the safety technology of intelligent vehicles, traffic safety research in the virtual reality environment can reduce the engineering cost of intelligent transportation system and improve the research and development efficiency.
