Description

technical field [0001] The invention belongs to the technical field of road traffic, in particular to a driving simulation system based on multi-agent traffic flow. Background technique [0002] With the rapid increase in the number of motor vehicles and new drivers in our country, the traffic accident rate has remained high, and traffic safety has received widespread attention from the whole society. Through the statistics of traffic accidents, it is found that the vast majority of traffic accidents are the result of the interaction of multiple factors including people, vehicles, roads, and the environment, and are the result of uncoordinated operation of system factors. very important. [0003] The traditional traffic safety analysis mainly starts with traffic accident patterns, accident causes, and road conditions. Through data analysis, accident black spots are found, and relevant improvement measures are taken. However, this method cannot truly obtain the driving oper...

Problems solved by technology

[0006] The existing driving simulation system is not only simple to set up the scene, but also the simulation of multi-agents in the complex traffic flow is only limited to the scope of observable functions. Except for the simulated driver's vehicle, the driving of other vehicles in the traffic flow is controlled at a fixed speed. drive in lanes to simulate the basic appearance of traffic flow

In the process of building the road environment, only a simple simulation of the basic information of the road, such as the establishment of street models, pavement models, road signs and markings, etc., the overall system is only used for demonstration, and cannot carry out accurate and s
