PTV Viswalk 9 Highlights

Higher, better, faster, stronger – those are the attributes of PTV Viswalk 9. The new feature “elevators” lifts up the pedestrian simulation software to a wholly new level. Furthermore, additional enhancements such as the introduction of new walking behaviour types on stairs and ramps, accelerated simulations runs as well as robust analytical result visualisation options make PTV Viswalk better than ever. 

Elevators

With PTV Viswalk 9 there is no vertical limit within the pedestrian simulation software. With the possibility to model now also elevators, users might simulate pedestrian flows within multi-storey buildings in a comprehensive manner – a feature that perfectly complements the possibility to import BIM data and thus to depict the entire architectural interior geometry in PTV Viswalk.  Elevators are a new type of network object in PTV Viswalk which can be added in the network editor like areas. Here, the software gives users the options to assign an elevator one or multiple doors and define their activity status at each level, e.g. on which the door opens. Furthermore, modellers may simulate single or several elevators applying different control logic, e.g.: If an elevator group includes only one elevator it processes all requests in one direction until there are none left to then turn around if there are further requests. If an elevator group consists of more than one elevator, the requests are distributed on these automatically.

Beyond powerful feature for modelling elevators, also the robust modelling options of pedestrians assures a comprehensive assessment of the flow of people within buildings. Here, users may simulate all pedestrians to take an elevator, assign them a path choice e.g. stairs or elevator, or use the new attribute in order to forbid pedestrians using an elevator on the way to their destinations at all. 

Introduction of new walking behaviour types

People need often more time when walking upstairs than downstairs. With PTV Viswalk 9 users may now model different behaviour types for pedestrians walking upstairs, downstairs or on ramps.

Persistent results for pedestrian grid cells

Result attributes for pedestrian grid cells, that were previously visible only during the simulation run, had been made persistent. This way, all calculated values connected to a grid cell can be saved in the evaluation data save file and used for visualisation after a simulation run. PTV Viswalk provides on top of that users with the possibility to graphically depict an array of values of a specific time interval of a simulation run, such as experienced velocity variance, experienced density etc., or to display a heat map with aggregated values from a multi-run simulations.

Faster simulation

Accelerated simulation runs are no problems with the new version of PTV Viswalk. The new calculation method within the pedestrian simulation software is sped up by factor 4 and is especially noticeable for interaction of pedestrians with public transport.
