About Sven Beller

In 1997, Sven Beller completed his studies in computer science at the Karlsruhe University of Applied Sciences and has been working for the PTV Group ever since. He currently works in product management for PTV Vissim and is a modelling expert for traffic simulations. His expertise covers Vissim expert level training courses, the modelling of intelligent traffic control systems and the creation of innovative pioneer applications including 3D modelling.

New PTV Vissim Demo Example ‘Cableways’

New example for PTV Vissim available now.

We have built an example that shows the simulation of cable cars in PTV Vissim. Two different systems are included in the model:

  • An up-the-mountain two-way system with two cable-connected cabins (holding up to 20 pax each)
  • A horizontal loop system with 11 cabins (holding up to 4 pax each) that travel non-stop

Both systems are interconnected at the mountain station where passengers can transfer from one system to the other.… Read more

New PTV Vissim/ PTV Viswalk Installation Examples ‘S-Queue With Shortcuts’

New examples for PTV Vissim / PTV Viswalk.

Today, we provide four variations of s-shaped pedestrian queuing zones where queuing aisles can be cut short. These shortcuts allow passengers to drastically reduce their walking distance at off-peak when most of the queuing area remains empty. Utilizing the new formula-based routing, a shortcut is opened as soon as the number of passengers in the next loop downstream is below a threshold value.… Read more

PTV Vissim Tip: Useful List Functionality

Vehicle Routeing Decisions – Vehicles Routes

Lists in Vissim offer a powerful way to edit network and other objects.

In addition to the obvious functionality here are some more features:

  • Move column: Click and drag a column header to the desired location. Upon dragging, a blue bar between two columns indicates the new location.

PTV Vissim Tip: Editing Attributes of Multi-Selections

Network_Objects_EVissim includes a variety of editing functionality. Editing an attribute of several network object at once is also possible as long as only objects of the same type are selected. There are two easy ways to accomplish this (the example is shown for “Links”):

  • Open the “Links” list and multi-select the desired links(using the Shift or Ctrl keys) or
  • In the network objects sidebar, select the “Links” insert mode and “Make no types selectable” from the shortcut menu.

#VisiOnAir: Modelling traffic-actuated signal controls with VisVAP

The use of traffic-actuated signal control has long been common in cities and local districts. Today, road users make the lights go green themselves, pedestrians by pressing a button, motorists using traffic detectors. “The traffic-actuated signal control is a response to current demand,” explains Sven Beller, modelling expert for smart traffic control systems at the PTV Group.… Read more

PTV Vissim Tip: Add objects with predefined attribute values

Surely you came across a situation in network coding where you wanted to add a new network object with the same values as an already defined one (e.g. when coding speeds in your Vissim network).

This is the ideal application for the duplicate functionality: Simply drag the desired object with the mouse while holding down the Ctrl key and place it at the position where it should be added.Read more
