STISIM Drive (SDL) - BARL - Roadway Barrels

Display a construction barrel or other lane marker in the display scene. Typically, temporary roadway construction zones use some type of a raised marker to alert the driver that some of the lanes ahead of them will be closed. In STISIM Drive you would use a series of BARL events to display the construction zone. Highway cones can also be used to mark off the boundaries of handling courses such as the Consumer Union lane change course. There are several different roadway markers to choose from and you can optionally set it up so that if the driver hits a lane marker, STISIM Drive can issue a collision. Since STISIM Drive uses 3D models of the roadway markers, the dimensions that were specified in previous versions of the program are no longer used.

EVENT PARAMETERS:

PARAMETER 1:

The longitudinal distance, in feet, that the lane marker is away from the driver when the lane marker first appears.

PARAMETER 2:

No longer used.

PARAMETER 3:

No longer used.

PARAMETER 4:

No longer used.

PARAMETER 5:

No longer used.

PARAMETER 6:

No longer used.

PARAMETER 7:

No longer used.

PARAMETER 8:

No longer used.

PARAMETER 9:

Lateral position, in feet, from the roadway’s dividing line to bottom left corner of the lane marker.

PARAMETER 10:

Barrel model index:

1 - Barrel
2 - Tube
3 - Cone

PARAMETER 11:

This parameter specifies any audio crash effect that will be played when the driver collides with the lane marker. The possible values for this parameter are:

0 – Do not generate a collision
1 – Generate a normal collision (based on current setting)
2 – Play audio file specified by Parameter 12

PARAMETER 12:

Lane marker crash sound file. If Parameter 11 is set to 2, rather than generating a collision (as specified by the Crash Options), a sound file is played. This option could be used to play a "thud" sound if a lane marker was hit. This would alert the driver that the marker was hit, but would not stop the simulation.

PARAMETER 13:

Volume control, 0 to 10.

Typically, you will be using the barrels to force the driver to change from one lane to another. To do this, you must put a group of barrels on the screen that slowly force the driver to merge from one lane to the next. The example event lines shown here, accomplish this task. Looking at the first line, you will see that the barrels are spaced longitudinally at 100 foot increments. After the BARL event designator, the next parameter tells STISIM Drive that when the barrels first appear, they are to be placed 1000 feet away from the driver. The ninth parameter tells STISIM Drive the lateral position on the roadway where the lower left corner of the barrel will be placed. As you can see in the example, the lateral position is incremented by 2 feet each time. This means that the initial barrel will be displayed at the roadway’s dividing line, and all subsequent barrels will be moved 2 additional feet to the right of the previous barrel. The tenth parameter tells STISIM Drive that if a driver hits one of the barrels, to play the sound file specified by the twelfth parameter, in this case a "thud" wave file. Finally, the last parameter specifies the volume setting for the sound effect file.
