What are the algorithms that the model uses for vehicle following and lane change?
The model uses the psycho-physical car-following model developed by Wiedemann. It uses vehicle-driver-units that incorporate several stochastic variations. Thus, there are virtually no two vehicles that have the same driving behavior.
For lane change, a related rule-based model is used that was originally designed by Sparmann.
We continuously develop both models to ensure up-to-date driving behavior in PTV Vissim.
