PTV Visum 17 Highlights

PTV Visum 17 is an evolution – a better, more powerful traffic software for transportation experts. The latest version lets you accomplish more with a world-first combined multi-modal assignment, simulation of vehicle sharing schemes, upgrades to the simulation-based assignment (SBA) as well as many other useful features and add-ins to enhance your experience. Check out the release highlights, and you may also find the nitty gritty details in the overview document.

Support for multimodal applications

In all other applications, combining private and public transport requires workarounds or specialised features such as auxiliary public transport. This is because private and public transport follows different underlying principles, and the approaches to modelling them are different. PTV Visum 17 brings with it the possibility to combine private and public transport models easily and intuitively, and thus model complex multi-modal trips that are becoming increasingly important with the emergence of new technology and Mobility as a Service.

Simulation of Vehicle Sharing schemes

It is becoming more apparent that vehicle sharing is important. Many major cities already have established car and bike sharing systems as their importance increases in the urban transport sector. The inclusion of such systems in macroscopic traffic models is, therefore, becoming more important for transport planners, public transport operators and providers of sharing systems.

For this reason, we have included Vehicle Sharing in the timetable-based public transport assignment in PTV Visum 17. With this inclusion, it is now possible to consider the standalone usage of sharing systems, both free-floating and station-based systems (round-trip and one-way), as well as trips combining traditional public transport with sharing systems.

Will the introduction of sharing systems affect the modal split in a city? Will it support public transport or compete with it? These questions may now be answered in PTV Visum. Furthermore, the new methodology enables you to determine the optimum balance between the number of vehicles, the effort required for relocating them and the user demand, thus minimising investment in the infrastructure of such systems.

Added extensions for simulation-based dynamic assignment (SBA)

In 2016 we released the simulation-based dynamic assignment in PTV Visum to a fantastic reception. The possibility to develop macroscopic and mesoscopic models within the same platform bring much-needed flexibility to transport planners and engineers. This year SBA has been extended to improve convergence in models with long assignment periods, better consideration of different user classes and include a warm start option.

New PrT assignment Bi-conjugate Frank Wolfe (BFW)

A new private transport assignment procedure has been implemented in PTV Vsum 17 called Bi-conjugate Frank-Wolfe (BFW). This procedure is a further enhancement of the Frank Wolfe (FW) method. The implementation is mainly motivated as a better converging alternative to the Lohse assignment (which is also a variant of FW) which scales effectively over multiple cores.

New procedure for matrix estimation

The matrix estimation procedure in PTV Visum – TFlowFuzzy – has been extended to include an alternative, simpler method called Least Squares which can always estimate an output matrix and in a faster time.

Global layout files to remember your favourite window configurations

A global layout file has been introduced in which the entire configuration of windows and views can be saved, providing you with more comfort and efficiency in your working processes. The layout files save window positions as well as settings for filter, graphics and layouts of all open windows including the tool windows.
