Attributes of vehicle travel time measurement

The Travel Time Measurement window opens automatically when you insert a network object and have selected to automatically open the Edit dialog after object creation (Right-click behavior and action after creating an object). By default, only the Vehicle Travel Time Measurements list is opened.

Into the window, you enter attribute values for the network object. For network objects which have already been defined, you can call the window using the following functions:

  • ►  In the list of network objects of the network object type, double-click the row with the desired network object.
  • ►  In the Network editor, select the network object of your choice. Then, on its shortcut menu, click Edit.

The network object may have additional attributes. In the network objects list of the network object type, you can show all attributes and attribute values. You can open the list via the following functions:

In the network objects list of the network object type, you can edit attributes and attribute values of a network object (Selecting cells in lists), (Using lists).

The objects of this object type may have relations to other objects. This is why the attributes list is shown as part of a coupled list (on the left). On the Lists toolbar, in the Relations box, you can show and edit the coupled list with the attributes of the desired relation on the right (see below Showing and editing dependent objects as relation) and (Using coupled lists).

Note: In lists, you can use the  Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list).

The list on the left may include the following attributes:

Element

Description

No

Number of travel time measurement. You can enter a different number.

Use a continuous numbering system for the Vissim network. This simplifies the evaluations.

Name

Name of travel time measurement

start section
  • Start link (StartLink): Number of the link of From Section
  • for Start position (StartPos): Distance between From Section and beginning of link or connector
  • Label: If this option is not selected, the label for an individual vehicle travel time measurement is hidden if the label for all vehicle travel time measurements is selected.
destination section
  • End link (EndLink: Number of link of destination section
  • for End position ( EndPos): Distance between destination section and beginning of link or connector
  • Label: If this option is not selected, the label for an individual vehicle travel time measurement is hidden if the label for all vehicle travel time measurements is selected.
Distance

Dist: Length of the Vissim determined shortcut (shortest possible path) from the From Section to the To Section.

If you change the value, the position of the To Section is automatically adjusted.

If no distance is entered, no continuous link sequence exists between both markers. An important connector is probably missing or one of the sections does not lie on the desired link, rather, for example, in the opposite direction.

Define a distance so large that the vehicles cannot traverse the From section and the To Section within the same time step. Vehicles that do not traverse the From Section and the To Section within the same time step are not accounted for in travel time management.

Showing and editing dependent objects as relation

The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

1.  In the list on the left, click the desired entry.

The list on the right contains attributes and attribute values of network objects, and/or base data allocated to the network object selected in the list on the left (Using coupled lists):

2.  On the list toolbar, in the Relations list, click > Delay measurements.

The delay measurements generated are displayed. All delay measurements can be newly generated (Defining delay measurement in lists), (Generating delay measurements in lists).
