Ptv Vision: VISUM 12 Fundamentals
VISUM is a software system that allows you to model all private and public transport types in one single integrated model. It is complemented by the microscopic traffic simulation system VISSIM. Together the programs form the PTV Vision system. Most basic data provided by transport information and planning systems can be managed consistently with VISUM and updated using a network editor. Unlike simple GIS systems, VISUM allows complex relationships within single or several transport systems to be retained, enabling you to create a suitable transport model.
