Note: This function is only available if the Signal offset optimization add-on is activated (Enabling or disabling add-ons). |
Using the signal time-space diagram, you can display the signal times of signal controls along a path (Fundamentals: Signal time-space diagram). The green bands start at the green times of the upstream (initial direction) signal controls. In accordance with the defined run time, they extend in driving direction to the next signal control. The diagram indicates whether a green band encounters a green time at the next signal control. In the diagram, you can adjust the offsets of signal controls in order to synchronize the green times.
For a signal time-space diagram, you need at least one user-defined path allocated to a user-defined path set (Creating a PrT path). The path must traverse at least two nodes or main nodes with signal controls. Start and end nodes are not counted here. Additionally, the cycle times of the signal controls must meet the following requirement: The longest cycle time must not exceed the greatest common divisor of all cycle times multiplied by eight.

Notes: If you want to find out how many user-defined paths exist in your version, choose the Network tab. Position the mouse pointer on the PrT paths button. A tooltip displays the information you are looking for. Signal controllers can have several signal programs. The signal time-space diagram shows the signal times for the currently allocated signal control. The allocation can be changed manually in the junction editor, for example (Switching off or manually changing signal programs in Visum). Via the procedure Set signal programs, you can automatically set the signal program for the relevant time period during a procedure sequence (Adding procedures to the procedure sequence). |
