Question

What kind of possibilities are there in PTV Vissim to model signal controller?

Answer

Fixed time signal control is included in the standard license. The add-on VISSIG provides additional functionality in the signal program editor beyond the PTV Vissim standard version. Models of several standard controllers for traffic actuated control are available as separate, independent products. Also available is VisVAP, a graphical flow chart tool to develop and edit an own vehicle actuated signal control logic including any type of special features (e.g. PT priority, railroad preemption, variable message signs on motorways etc.).
