Opening a signal time-space diagram

1. From the View menu, choose Signal time-space diagram.

The Signal time-space diagram window opens.

Tips: You can also open the signal time-space diagram by clicking the Open signal time-space diagram icon.

If a window with a signal time-space diagram is already open, you can open a second signal time-space diagram. To do so, select the Signal time-space diagram menu > Next signal time-space diagram entry.

2. Click the Path (initial direction) button.

The Select path (initial direction) window opens. Here you see a list of all user-defined paths that traverse at least two nodes or main nodes with signal controls.

3. Make the desired changes.

Element	Description
Key	You can use this input field to jump directly to a path in the list below. The path key consists of the path set number, a semicolon, and the path number. Enter a number to select the first path of a path set. Example: Enter 5 to select the first path of path set 5. Enter a semicolon and the number of the path to select the first path with this number. Example: Enter 3 to select the first path with the number 3.
Path set	Use the drop-down list to specify that only paths of one path set are displayed in the list. Note In this context only user-defined path sets are available. Demand segments are not displayed.
Filtering	Use the drop-down list to restrict the number of paths that are displayed in the list. All routes All routes are displayed. Filter for OD pairs The list only contains paths with a zone as a start and ending point. The properties of this zone must correspond to the current OD pairs filter (Exception: Filter for OD pairs).

4. In the drop-down list, select the desired path.

5. Confirm with OK.

The path you selected is displayed in the signal time-space diagram.

Tip: Alternatively, to open the signal time-space diagram, in the Paths window, right-click the path of your choice. Then, from the shortcut menu, choose Signal time-space diagram for path(Opening the Paths window). In this case you have the advantage that you see the course of the path in the network. Another possibility is to use the PrT paths list and right-click the path you want. Then you select in the shortcut menu the Signal time-space diagram for path entry.

6. If required, use the Path (reverse direction) button to insert a path for the reverse direction.

Note: For the reverse direction you can only use paths which have the following properties:

The path must have at least two common nodes with the path of the initial direction.
The common nodes of the initial and reverse direction must occur in reverse order.

The paths of your choice are displayed in the signal time-space diagram (The signal time-space diagram window).
