A good virtual reality experiment must be associated with a strong sense of immersion, high environmental fidelity, positive
interaction and little negative impact. The integration of the two simulators will fulfill these characteristics and enhance
the ability of both traffic modeling and driving simulation, enabling a new direction of controlled virtual reality experiments.
For the DS, the integration can generate a more realistic traffic environment and present multi-vehicle interactions, to
strengthen the validity of and immersion into the scene and also strengthens the ability to test special driving behaviors.
For the MTS, the researchers or engineers can not only calibrate the fundamental traffic flow models in the simulation model
by comparing the behaviors of the user-driven vehicles and the simulated vehicles but can also create and test new suitable
models.
