Inserting a new network object in a Network Editor

Notes:   You can specify that you need not press the Ctrl key when adding network objects (Right-click behavior and action after creating an object). For some network objects there are windows in which the attributes of a network object can be defined and edited. There are lists for this, for all network objects. You can choose whether you want to open a window, a list or neither of the two for the definition of network objects in the Network Editor (Right-click behavior and action after creating an object).

On the network object sidebar, the desired network object type must be selected.

Network objects can be superimposed in the Network Editor. While you add a new network object, you can select the superimposed network objects until the network object, to which you want to add the new network object, is marked (Selecting a network object from superimposed network objects).

Vissim saves various attributes when inserting a network object so that they are applied the next time a network object of the same type is inserted, for example, a layer or display type.

Notes:   When creating network objects, be careful not to extend the network too far. Very large networks or network objects can cause insufficient memory to perform a simulation run. Do not create network objects far from the background map reference point. The further the distance between network objects and reference point, the more likely scaling errors occur. As a result, lengths are no longer interpreted correctly.

Commands for inserting new network objects

If on the network object sidebar, you selected a network object type, you can insert network objects into the Network editor via the following functions:

• Via the shortcut menu of the network editor If for the network object type, you inserted a start section for the network object and afterwards need to insert one or multiple destination sections, the respective function is displayed in the shortcut menu.
• Depending on the user settings, using the right mouse button or normally using the right mouse button and the Ctrl key (Right-click behavior and action after creating an object)

Inserting new network objects in available positions or on other network objects

Independent from network object type, you can enter network objects in available positions or you must place network objects on other network objects. This is described for each network object according to the definition of the network objects (Network objects - overview).

• You can enter, for example, links or areas onto available positions in the Network Editor. Thereby, you can cut or overlap network objects.
• You must place network objects of other network object types on network objects. For example, you can insert desired speed decisions, reduced speed areas, priority rules, detectors, parking lots, vehicle routes, vehicle inputs, vehicle travel time measurements, etc. onto links. Insert pedestrian inputs, sections for area measurement or pedestrian travel time measurements onto areas. Network objects, start sections or destination sections cannot be inserted on connectors for reverse parking.
• For vehicle travel time measurements and pedestrian travel time measurements, insert a From Section and a To Section.
• On a link, you add a start section for priority rules, vehicle routes and pedestrian routes; you can also add one or more destination sections.
• For network objects that have a start section and multiple destination sections, you can select the start section again later on to insert additional destination sections or move them.

Work steps during addition depend on the network object type

After you have begun to add a network object, the further steps until the network object is fully added depend on the network object type. These steps are described in the definition of network objects (Network objects - overview). There are the following differences:

Network object types whose length is defined by dragging the mouse

• Links: While dragging the mouse, you can use the left mouse button to set intermediate points and change the direction there later (Defining links).
• Reduced Speed Areas (Defining reduced speed areas)
• Parking Lots (Defining parking lots)
• Detectors (Defining detectors)
• Public Transport Stops (Defining PT stops)

For these network object types, the following applies:

• ►  When the desired length is achieved by dragging the mouse, release the Ctrl key and the right mouse button.

• For connectors, the following applies:
• ►  When the desired position is reached on the destination link by dragging the mouse, and the edges of the destination link are marked by arrows along the direction of travel, release the Ctrl key and the right mouse button (Defining connectors).

Notes:   You can specify that you need not press the Ctrl key when adding network objects (Right-click behavior and action after creating an object). For some network objects there are windows in which the attributes of a network object can be defined and edited. There are lists for this, for all network objects. You can choose whether you want to open a window, a list or neither of the two for the definition of network objects in the Network Editor (Right-click behavior and action after creating an object).

Network object types with a marker

• Desired Speed Decisions (Defining desired speed decisions)
• Stop Signs (Defining stop signs and toll counters)
• Signal Heads (Defining signal heads)
• Vehicle Inputs (Defining vehicle inputs)
• Data Collection Points (Defining data collection points)
• Queue Counters (Defining queue counters)
• Pavement Markings (Defining pavement markings)
• 3D Traffic Signals (Defining 3D traffic signals)

For these network object types, the following applies:

• ►  Once the network object is inserted, release the Ctrl key and the right mouse button.

Network object types with a start section and a destination section

• Public Transport Lines (Defining PT lines)
• Vehicle travel time measurements (Defining vehicle travel time measurement)
• Pedestrian travel time measurements (Defining pedestrian travel time measurement)

1.  When the desired position of the destination section is achieved by dragging the mouse, click the right mouse button.

2.  Release the keys.

Network object types with a start section and several destination sections

• Priority Rules (Defining priority rules)
• Vehicle Routes (Defining static vehicle routes)
• Pedestrian Routes (Defining static pedestrian routes)

For these network object types, the following applies:

1.  Repeat the next two steps until all destination sections have been inserted for the network object:

2.  Move the mouse pointer to the desired destination section position.

3.  Click.

4.  After having inserted all destination sections for a network object, click into an empty section of the Network Editor.

Planar network object types

You can add planar network objects as a rectangle, circle or polygon (Defining construction elements as rectangles), (Defining construction elements as circles), (Defining construction elements as polygons).

• Areas
• Obstacles
• Ramps & Stairs
• Sections

For these network object types, the following applies:

• ►  If inserted as rectangle: After drawing a rectangle to the desired size, double-click.
• ►  If inserted as polygon: After adding the desired number of polygon points, double-click.

Graphic file of a background image

The background is inserted and selected. You can change its size via the corner drag points (Inserting a background image).

• ►  To quit creating network objects, click an empty section in the Network editor.

Nodes

• ►  Once you have added the desired number of the polygon points, double click (Defining nodes).

Behavior after addition

Depending on the user settings and the network object type, a window or a list can open - immediately after adding a network object - or none of the two (Right-click behavior and action after creating an object). In the window or the list, you can enter input attributes for the network object.

When you insert 3D models or 3D traffic signals, a symbol is inserted and a window opens. There, you can select the desired file.

When you insert a background, a window opens. There you can select the desired graphic file.

After insertion, a network object is automatically selected. This allows you, for example, to copy it or position it exactly.

Adding a network object to a level

The network objects of some network object types can be placed on levels, for example links, areas, stairs or ramps, obstacles, background images, sections, fire events, static 3D models or 3D traffic signals.

When creating the network object, Vissim selects the level in which the network object will be placed, depending on the selected level visibility:

• When levels are defined and set to visible, the network object is created in the visible level with the lowest number in the current network editor.
• If all levels are invisible or no network editor is open, the network object is generated in the lowest-number level.

You can change the level assigned to a network object in the attributes of the network object and assign a different level.

Adding a network object at the beginning or end of a connector

You can place a network object on the same link coordinates as the beginning of an outbound connector or exactly at the end of a connector. Vehicles that change links at this position will recognize the network object. This means that a conflict area, e.g., that ends precisely at the end of a connector, will work as expected.

Canceling addition of network objects

You want to cancel the insertion of a network object depending on the network object type:

• ►  To cancel the insertion of a start section, in the Network Editor, move the mouse pointer to an empty section and release the right mouse button.
• ►  To cancel the insertion of a destination section, in the Network Editor, move the mouse pointer to an empty section and double-click.
• ►  To cancel the insertion when a window with attributes is open, release the mouse buttons and press the Esc key.
• ►  To cancel the insert of a construction element, release the mouse buttons and press the Esc key.
