STISIM Drive (SDL) - S - Stop Sign

Display a STOP sign. If the driver runs the stop sign, nothing happens.

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. Because the roadway is more flexible in STISIM Drive than it was in the DOS version of STISIM, we have added some additional functionality to this parameter. If this parameter is specified as a negative number, then the program will automatically figure out (to the best of its knowledge based on the current roadway) where the stop signs will be placed. Otherwise, it will act as specified. This option was added because it is now easy to have the roadway transition from a set number of lanes to another set number of lanes and if you are trying to use a PDE that has stop signs in it and the roadway is a different size, you may have trouble. The longitudinal distance is still the same, it just has a minus sign (-) in front of it. If you are using this option, you must make sure that the stop sign event lines up with the intersection event, otherwise the signs will be mis-aligned. For example if you have an intersection that is 1200 feet away, you want the stop sign event to be -1200 feet away.
PARAMETER 3:	The number of signs to display: 0 - Single stop sign in the driver's direction 1 - Single stop sign in the driver's direction 2 - 2 way stop in the driver's direction 3 - Single stop sign in opposing traffic's direction on right 4 - 4 way stop 5 - 2 way stop in the opposing traffic's direction 6 - Single stop sign in opposing traffic's direction on left

EXAMPLE:

1000,S,0,1000,2

1000,S,0,-1200,4
2200,I,0,0,1

In the first example shown, the stop signs will appear after the driver has driven 1000 feet down the road. When the signs initially appears, it will be 1000 feet in front of the driver. Since parameter 3 is set to a value of 2, there will be a stop sign in the driver's direction and in the opposing traffic's direction. In the second example, a 4 way stop will be created 2200 feet into the run. Since a value of -1200 is used for the longitudinal distance, STISIM Drive will automatically place the signs based on the middle of the intersection being at 2200 feet.
