PTV launches new release of its Visum transport planning software
PTV has launched a new release of its transport planning software, giving users a host of new features.
PTV Visum 14 inlcudes new functionality such as:-
Whether on your way to work or on the way home, you may well decide to make an unplanned stop, at the shops en route, for example. Such spontaneous detours which inevitably occur in our daily lives, can now be modelled more realistically. In order to achieve this, “rubberbanding” has been added to Visem’s tour-based demand modelling. “With rubberbanding, starting point and main activity as well as intermediate stops are connected with – metaphorically speaking – a rubberband,” explains Dr.-Ing. Johannes Schlaich, Director of PTV Visum Product Management & Services. “The stronger the rubberband, the more likely it is for example, that the shops in the activity chain Home-Work-Shopping-Home are situated on the route between home and work.”
Last year “distributed computing” was introduced. This allows users to distribute scenarios across multiple computers, in order to calculate them in parallel with one another. With PTV Visum 14, it is now possible to use distributed computing also outside the scenario management. Selected procedures such as private and public transport assignments, and Visem calculations of different demand strata, can now be calculated on different computers in parallel. Once completed, the results from the different computation nodes are automatically merged.
PTV Visum 14’s Public Transport (PuT) timetable editor has been completely updated and now includes several requested functions, such as the ability to freely edit the stop sequence using a graphical editor. Furthermore, the new incremental PuT-importer ensures rapid importing and updating of PuT supply from one file version to another. “The new PuT-importer does not only allow the transfer of PuT supply completely into a street and rail network, but also replaces or supplements existing elements of an existing PuT network,” explains Schlaich. “This represents a huge reduction in the modeller’s workload – in particular when it comes to regular timetable updates.”
