According to the method for achieving the interactive integration experimental platform of the microscopic traffic simulator and the driving simulator, good simulation can be carried out on real road traffic circulation states, a virtual experiment scene which is more real is provided for the drivers, applied range of the driving simulator is outstandingly improved, and reliability and accuracy of the driving simulation experiments are improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation system and traffic simulation, and more specifically, the invention relates to a method for realizing an interactive integrated experiment platform of a microscopic traffic simulator and a driving simulator. Background technique [0002] The road traffic system is a complex system composed of four elements: people, vehicles, roads, and traffic environment. These elements act independently and restrict each other, and jointly determine the operation status of this complex system. It is very difficult to theoretically analyze driving behavior by using mathematical models in the traditional way, while on-site demonstrations are limited by the conditions of the actual scene, the implementation cost is high, and the safety is not high. Therefore, it is a new method to conduct experimental research on driving behavior. technical means. The development of virtual reality technology ha...

Problems solved by technology

In more complex traffic flow scenarios, the simulation of traffic flow mainly adopts fixed traffic flow settings, that is, the movement rules of surrounding vehicles are set in advance to drive on a fixed route, which cannot reflect the relationship between the vehicle controlled by the driver and the surrounding vehicles. The dynamic interaction behavior of the system cannot reflect the overall change characteristics of the system caused by the interaction of traffic flow (such as traffic flow stop wave, start wave, etc.)

That is to say, the advantage of the driving simulator lies in the virtual experiment on the behavior of a single car. How to study the impact of individual driving behavior on traffic flow? The current technology and methods are still "powerless"
