Description

technical field [0001] The invention relates to the technical field of traffic driving, in particular to a traffic and driving interactive virtual simulation system. Background technique [0002] The use of computer simulation technology to study traffic problems has the characteristics of economy, safety and high efficiency. At present, in the field of highway traffic, computer simulation technology is mainly used in two aspects of traffic simulation and driving simulation. The traffic simulation system solves problems in the fields of traffic management, road planning, traffic impact assessment, and driverless vehicle testing by simulating the dynamic characteristics of road networks and traffic flows. [0003] Automobile driving behavior has many characteristics such as complexity, ambiguity, self-learning, and correlation. Most of the traditional car driving training models use real car teaching, and the teaching application is limited. The performance of driverless v...

Problems solved by technology

[0005] However, the existing traffic simulation scenes generally simulate and construct virtual traffic data according to certain rules or use pre-recorded traffic data. Since the simulated vehicles do not exist during the data recording process, it is impossible to realize the interaction between the simulated vehicles and the traffic scene during the simulation process.

However, the virtual traffic data simulated and constructed according to certain rules are often different from the real traffic data, and the authenticity is poor.
