STISIM Drive (SDL) - SA - Signal Ahead Sign

Display a diamond sign with a traffic signal displayed on it. This is to used alert the driver that a traffic light is approaching. This event should no longer be used and instead you should create the roadway sign using the SIGN event.

EVENT PARAMETERS:

PARAMETER 1:	Not used (set to zero). This remains in the format to keep event files that were created for previous versions of the program compatible with this version.
PARAMETER 2	The longitudinal distance, in feet, that the sign is away from the driver when the sign initially appears.

EXAMPLE:

1000,SA,0,1000

This event is used to inform the driver that they are approaching a signal light. In the example shown, the signal ahead sign will appear after the driver has driven 1000 feet down the road. When the sign initially appears, it will be 1000 feet in front of the driver.
