If you already use PTV Vissim with PTV Viswalk, you probably know that it is a powerful tool for simulating pedestrian movements in train stations, which is an important part of planning and designing of stations. In this process, PTV Vissim helps you ensure the free and safe flow of pedestrians in all areas of the station: The main hall, the underpasses and corridors, the stairs, and along the train platforms. The new version of PTV Vissim, now available for download, can do even more when modelling public transport.

  1. The first improvement is formula-based boarding. It allows more detailed and specific boarding proportions, even per train line or train number. That is a major advantage when modelling transfers between trains. Not only does it require less network objects, but also it allows different proportions over the time of day. For example, in the morning you have a different distribution of alighting passengers compared to noon.
  2. An additional advancement is that the new version enables you to set the waiting location distribution. It is based on platform entry and realistically models the most populated zones on a platform.
  3. Thirdly, segments of the train without passengers can now be set, to achieve a better door distribution for alighting passengers.  
  4. And the fourth improvement is that trains can change their driving direction at a public transport stop. That’s especially important at terminus stations.  It requires and overlapping link in the other driving directions and once the change of driving direction is activated for the PT Line Stop, the PT vehicle will continue there.

Hello, I’m Jochen from PTV Group.

If you already use PTV Vissim with PTV Viswalk, you probably know that it’s a powerful tool for simulating pedestrian movements in train stations, which is an important part of planning and designing of stations.

In this process, Vissim helps you ensure the free and safe flow of pedestrians in all areas of the station: The main hall, the underpasses and corridors, the stairs, and along the train platforms.

The new version of Vissim, now available for download, can do even more when modelling public transport.

The first improvement is formula-based boarding.

It allows more detailed and specific boarding proportions, even per train line or train number.

That’s a major advantage when modelling transfers between trains. Not only does it require less network objects, but also it allows different proportions over the time of day. For example, in the morning you have a different distribution of alighting passengers compared to noon.

For Boarding Passengers at PT Stops, you can add a formula for a filter, which defines which proportions are valid for individual passengers, for example depending on the train they coming from.

An additional advancement is that the new version enables you to set the waiting location distribution. It’s based on platform entry and realistically models the most populated zones on a platform.

For example, it enables you to omit sections with no waiting passengers due to exit ramps. No longer do you need to split the public transport waiting area.

There is a new attribute for waiting areas which allows you to define a certain distribution as a distance distribution along the waiting area.

Thirdly, segments of the train without passengers can now be set, to achieve a better door distribution for alighting passengers.

For you 2D3D models, you can define the sections without passengers front and back for each 2D3D model segment.

And the fourth improvement is that trains can change their driving direction at a public transport stop. That’s especially important at terminus stations.

It requires and overlapping link in the other driving directions and once the change of driving direction is activated for the PT Line Stop, the PT vehicle will continue there.

We hope these improvements will upgrade your Viswalk simulations.

The new Viswalk version is now available for download. And we’d love to get your feedback – so let’s chat at the Vissim Users Forum on LinkedIn.
