Pedestrian Network Objects
Vissim performs pedestrian simulation based on the Wiedemann Model. If the PTV software Viswalk is added on as a module, pedestrians can be simulated using the Helbing Model (Social Force) or Weidemann Model. Please see the user’s manual for information and publications on these pedestrian models. PTV Viswalk can also be used as a stand-alone software to simulate pedestrians without vehicles. This section focuses on the Wiedemann Model only, using Vissim 7.0 as stand-alone without the Viswalk Add-on.
Vissim uses network objects to define geometry, attributes, data input to allow the model to meet the users end need. The Network Objects section introduces the pedestrian Network Objects. The Pedestrian Simulation section discusses how to place pedestrian network objects, input data, set up simulation parameters, and evaluate the model in order to create a quality model.
The pedestrian simulation network objects in Vissim are as follows:
Areas (Polygon or Rectangle)
Obstacles
Ramps and Stairs
Pedestrian Inputs
Pedestrian Routes
Pedestrian Travel Times
Pedestrians in Network
Links
Priority Rules
Signal Heads
Detectors
Section
Background
3D Traffic Signals
Static 3D Models
The tools for creating these objects can be found in the Network Objects Toolbar shown in the figure below. If desired, to view pedestrian object types only:
Right Click anywhere in the Network Objects Toolbar and select Pedestrian Object Types Only.
To go back to the previous view and display all the Network object types in the toolbar, simply reverse the process and select “All Object Types”.
