PTV Viswalk Functions

Graphical editor (GUI) that allows users to work with the following elements:

  • Areas as walkable space for pedestrians (rectangles, any polygons)
  • Obstacles blocking the walkable areas to pedestrians (rectangles, as polygons)
  • CAD import (DWG files) for areas and obstacles
  • Option of integrating additional formats as a background image (JPG, PNG, BMP, DXF, DWG, SHP and others)
  • Routes predefining the pedestrians' walk from area to area
  • Routing decisions where the pedestrians chooses a route from the set of routes
  • Inputs that define by time interval how many pedestrians will enter the simulation at which time
  • Alternative option to the inputs/routes concept: definition of demand and routes using origin-destination matrices (interval-dependent)
  • Access to the model parameters (Social Force Model), including desired speed
  • Desired speed distributions which can be entered and changed according to user preferences
  • Unlimited number of levels (storeys)
  • Ramps and stairs connecting levels
  • Escalators (and moving walkways) connecting two levels
  • Moving walkways which - similar to escalators, but without a difference in height - also move standing pedestrians
  • 2D view and 3D view are already provided during the simulation and model creation. Users can toggle between the two views
  • LOS display
  • AVI recording of animation - results export to 3D Studio Max PTV Viswalk and replay in PTV Viswalk
  • Flexible design options for areas, obstacles and pedestrian models
  • Possibility of assigning individual areas different walking behaviours (speed distribution and parameters)

Measurement areas

  • Measurement of various parameters of individual pedestrians (e.g. time spent at measurement area, average speed, etc.)Time-aggregated measurements
  • Journey time and distance measurement: "from area A to area B"
  • Queuing data and -analysis (time-aggregated)
  • Congestion identification
  • Partial routes for local redistribution in line with the implicitly or explicitly defined origin-destination matrix
  • Dynamic potential: calculation of the desired direction based on the estimated remaining journey time (in contrast to the calculation of the desired direction based on the shortest distance). "One-shot assignment"
  • Priority rules: adoption of this concept from the PTV Vissim vehicle simulation allows for the simulation of specific situations, such as:
  • COM access
  • High time resolution: up to 10 simulation steps per second
