1) Start Vissim

2) Click on EDIT – USER PREFERENCES

3) Select NETWORK EDITOR under GUI.

User preferences

� Network Editor

� Creates a new object

� Show edit dialog if available, show list otherwise

In this course, we use the option “opens the context menu for Right click behavior”.

Hence, to create any new object in our network, we need to hold the CTRL (Control) button

and click on RIGHT MOUSE CLICK.

Second option:

In Automatic action after object creation select Show edit dialog if available, show list

otherwise.

PTV Vissim - Scenario Management

In the given training material, you can find these 2 folders (see figure) under the main

folder “PTV Vissim – Scenario Management”.


9

Example_ScenarioManagement

1_Example_Mini

Select the network file (*.inpx) along with the other required files (i.e. signal file,

background file, layout file etc.) and put those into a new folder, i.e.

Example_ScenarioManagement. (See figure)

If you are not copying the files into a new folder, the original network file (*.inpx) will be

always opening in the Scenario management. As a result, you might lose the original

version of your network file.

Please make a copy of your network file in another folder in order to avoid this issue.


10

As an example, for the application of Scenario Management in PTV Vissim, one existing

model will be used.

An intersection is to be evaluated with three different control methods.

Scenario 1: Right of way

Scenario 2: Signal controlled junction

Scenario 3: Roundabout

31

1) Go to the PROJECT EXPLORER tab.





to insert the second modification.

4) Insert “Parking Area” on the Name field.

5) Double click on the modification Parking Area for editing.

Modification 3

We are going to additionally read another file to our Base network in the third modification.

You can find a prepared file named “PARKING_AREA.INPX” in the following directory:“…\PTV Vissim - Scenario Management\

1_Example_Mini\Example_ScenarioManagement”.


32

1) From menu FILE, navigate to READ ADDITIONALLY and select NETWORK…

2) Select PARKING_AREA.INPX from the SELECT FILE TO READ ADDITIONALLY dialog

box and click on OPEN.

3) It will take few seconds to read the additional file into our Base network.

Make sure that the

selection

boxes for the column

“Read” is not checked by

clicking on

“MARK NONE

FOR READING”

Modification 3


33

1) Select MARK NONE FOR READING from the READ ADDITIONALLY dialog box

2) Select the following network objects to read:

• Links

• Parking Lots

• Reduced Speed Areas

• Conflict Areas

• Parking Routing Decisions

3) Click on OK

4) It will take few seconds to insert the new objects in the existing base network.

5) The “Parking Area” has been added to the northern part of our network.

Modification 3


34

1) Connect Link 16: South Bound, 1L with the parking area

2) Create an entering and an exiting connector to the parking area (see figure

above)

3) Define appropriate spline points for the connectors.

Modification 3


35

1) Select VEHICLE ROUTES from the Network Objects window

2) Change the position of the Parking Routing Decision: 1 to the northern part of

Link 16

3) Select YES TO ALL to complete the parking routes.

Modification 3


36

1) Add a REDUCED SPEED AREA on the entering connector to the parking area

and define 25: 25 km/h as the desired speed distribution.

2) Add one DESIRED SPEED DECISION on the entering connector (on the middle of

the Reduced Speed Area added on step 1). The Desired Speed distribution

will be again 25 km/h, so that vehicles can have lower desired speed in the

parking area than usual (50 km/h).

3) One more DESIRED SPEED DECISION should be added on the exiting connector

and the desired speed distribution will be 50 km/h, so that vehicles can have

higher speed while exiting the parking area.

4) Solve the CONFLICT AREAS for both entering and exiting connector to and from

the parking area. As you can see on the given figure, Undetermined has been

selected for the branching conflict and the through traffic coming from North

will have priority over the exiting traffic from the parking area.

5) Save the modification.

NEW SCENARIOS


37

Scenarios 4-6


38



STRUCTURE...



4) Insert “Right of Way + Parking” on the Name field. This is the 4th scenario in

our project.

5) The fourth scenario depends on:

3. Parking Area

6) Add the fifth scenario named as “SCJ + Parking”.

7) This scenario depends on:

1. Signal Controlled Junction and

3. Parking Area

8) Add a new scenario 6: “Right of Way + Parking”.

9) Our sixth scenario depends on:

2. Roundabout and

3. Parking Area

Now you can open the scenarios 4 to 6: e.g. Right of Way + Parking will look like this:

Hint for scenario 6:

Roundabout + Parking, you will get a few warning messages as some of the conflict areas

do not exist on the scenario.


39

Simulation of one Scenario


40

1) On the Project Explorer tab, you can select a particular scenario, i.e. 2: Signal

Controlled Junction

2) With the blue play button, now you can simulate this selected scenario.

Simulating multiple scenarios


41

1) You can select multiple scenarios with the help of CTRL button.

2) And then the same blue button will be used for running multiple selected

scenarios.

Simulating all scenarios in project


42

1) The double play button is used for simulating all scenarios.

2) With just one click all the scenarios will be simulated one after another.
