Using signal control procedures
You can define new signal controllers with your signal groups. To do so, for the control procedure, select a type. This e.g. specifies whether you want the signal controller to be fixed-time controlled or controlled via a control procedure. Depending on your Vissim license, you can access add-on modules with external signal control procedures (Showing licensed signal control procedures).
Determining the cycle second for a fixed cycle time
Vissig determines the current cycle second for the signal controller type Fixed time.
For the signal controller types VAP, TRENDS, VS-PLUS and Siemens VA, Vissim determines the current cycle second.
The signal control types, 2-stage control, level crossing, and pedestrian protection, do not involve cycles. As a result, their cycle duration is set to 0 seconds.
- In Vissim, the first cycle starts at 00:00:00. At the simulation start, the cycle second is calculated based on this start time.
- If the start time (time of day) specified in the simulation parameters is 00:00:00, the cycle and simulation start at the same time.
- If the start time (time of day) specified in the simulation parameters is not 00:00:00, at the simulation start, the current cycle second may have a value other than 0, as the first cycle was started at 00:00:00.
Some control procedures expect the supply file to be saved in the same directory that contains the *.inpx file. If a control file is saved to a directory that does not meet the requirements of the control procedure, this can cause the program to crash. The supply files of the control procedures Fixed time/Vissig, VAP and RBC can be saved to any directory Vissim can access. Vissim does not need the supply files to be saved to a specific directory. Should you have any questions regarding supply files, please contact the company that developed the control procedure.
