PTV Visum is a complete software package for traffic analyses, forecasts and GIS-based data management on city, regional or national levels. It consistently models all transport modes and their interactions in a unified network data model. Sophisticated tools for management, import/export and editing of network elements, traffic demand and related datasets allow to efficiently build up large transport models.
The included methods cover demand modelling and forecast, different assignment methods adapted to different types of traffic (various highway assignment procedures, dynamic traffic assignment, mesoscopic assignment, headway-based an timetable-based public transport assignment, stochastic assignment for slow modes,…) and various processing and analysis tools. Beyond the scope of typical strategic transport modelling tools, the methods provided in PTV Visum reach far into the operational realm, e.g. by including traffic engineering tasks related to intersection design and signal controlling, or by providing operational KPIs for public transport operations down to the level of line blocking and fleet allocation.
All methods can be embedded in a comprehensive scenario management environment, allowing to develop and compare different variants of transport infrastructures and policies. Powerful tools for graphical and numerical data analysis (thematic maps, 3D plots, filtering and aggregation in tables, matrix analayis,…) allow to evaluate and present the modelled data in very accessible form.
