PTV Vissim 10 Release Highlights
A better, more powerful evolution of our traffic simulation software
Meet the new generation of PTV Vissim - including new features and updates to further enhance your experience. PTV Vissim 10 offers matrix estimation, reverse parking, flow bundles and much more. Dynamic functionalities and visualisation have always been the backbone of PTV, and this is enhanced in the latest version. All detailed information about the new features are available in the overview document.
Implementation of matrix correction
Building on PTV Vissim 9 which included inbuilt matrices, PTV Vissim 10 extends the functionality by enabling users to correct, or estimate, the origin-destination matrix by matching it to counted data on links for both multiple and single time intervals.
In the dialog box, the matrix to be corrected is selected, as well as the link attributes where the traffic counts are stored and the path attributes where the volumes are stored. This method for matrix correction is the method of least squares similar to PTV Visum 17. The sum of squares of differences between counts and volumes plus the sum of squares of differences between corrected and original matrix values is minimised.
Modelling reverse parking
Modelling vehicles’ parking manoeuvres in PTV Vissim now provides users with a new option in vehicle parking behaviour. With the additional attribute Parking Direction “forward in and reverse out” followed by the change of driving direction from reversed out parking to moving forward, the new variant makes sure that replicating vehicles reversing out of parking spaces can be depicted simply and realistically. Furthermore, customizable settings such as the speed of reverse driving, gap times, reverse speed and time distribution when changing direction provide a robust base for simulating parking operations at a high level of accuracy.
Flow bundle feature
PTV Vissim 10 emphasises visualisation and usability tools to assist complete your projects. Here, the new network object “flow bundle” enables users to visualise, at a specified location in the network, where all the vehicles have entered and exited the network. The visualisation options for those traffic volumes of all routes passing a specific link position are shown as flow bundle link bars. They are represented in colour schemes and are flexible to be altered for different parameters including time intervals. For exemplifying the number of vehicles crossing each link, aliases depicted as link labels support the visualisation effect of the flow bundle.
Node evaluation visualisation
Another upgrade to visualisation of data in PTV Vissim 10 is included with node evaluation visualisations. This feature allows all evaluation data from nodes to be presented graphically in the user interface as well as in results lists. Therefore turn volumes, queue lengths, delay etc can all be demonstrated in a clear visual manner.
Legend in network editor
In PTV Vissim 10, a legend listing the values and active colour schemes of attributes in the network such as vehicles or links can now be shown in the network editor window. The location and size of the legend can be set in the basic graphic parameters of the network editor window.
For each attribute of any object in the data model, an alias can be defined, either in the list of aliases accessible from the main menu or through a new button in the attribute selection dialog. A defined alias is listed alphabetically in the attribute selection dialog on the left side and can be selected as any other attribute. This is especially useful for indirect attributes with long names in list windows (column headers), charts, legend and anywhere else where a shorter but significant name is more helpful.
Improved Scenario Management – Run Control
With PTV Vissim 10, users can define the number of simulation runs for every scenario individually, or apply it directly to multiple scenarios. Furthermore, the legend within the Project Explorer gives a clear overview of the status of the simulation run by demonstrating if a scenario is in progress, in waiting process or completed.
Directly Import 3D Models
In PTV Vissim 10 users can directly import SketchUp (*.skp); 3DS-Max (*.3ds) and Autodesk (*.dwf) files as vehicle models into a simulation meaning any vehicle brand or model can be included in visualisation of simulation models.
Unity Interface to PTV Vissim
As an extension to PTV Vissim’s driving simulator interface, an example project in Unity is provided. When starting the Unity application, a network defined in PTV Vissim opens in Unity and vehicles controlled by PTV Vissim are displayed in Unity. In addition, vehicles can be controlled by Unity like in a driving simulator.
