Add-on module RBC

|
Notes:
|
The Ring Barrier Controller (RBC) is integrated into Vissim. The RBC provides users with a seamless way of simulating various types of signal controllers in a Vissim model.
During a simulation Vissim passes the status of its detectors and signal heads to the controller and the controller returns the state of the signal heads for the next simulation time period. The simulation time period used for this interaction is determined by the Controller Frequency and can be as small as one tenth of a second. The RBC Editor allows the user to set the timings used during the Vissim simulation by the controller and stores these values in external RBC data files with the *.prbc file extension.

Note: When you add, delete, or change signal group numbers, save your Vissim file. Otherwise your Vissim file may become incompatible with your controller files! |
