How do we leverage this for winter operations?

White River bridge on I-465

Geo-fenced target zone for automatic turn on/off

Turn on/off 100ft from bridge deck

Example: Treating bridge decks and under passes

10

Conceptual FrameworkGenerate shapefile with target zones and application rates

Load the job with generated shapefile

No

Turn off all nozzles

Yes

Is there an overlap from

previous run?

Is the tanker within target

zone?

Turn on all nozzlesTurn on nozzles outside overlap

Yes

No

Automatic turn on/off

Precision application

Rate control

No double application

Job Sync

• Automatic turn on/off at pre-defined target areas

• Precision application (1-2cm accuracy on ground)

• Automatic shut off at previously applied areas

Data Analytics

If actual rate > target rate

Total duration = 1 min 35 secTotal area covered = 0.10 acresTotal volume applied = 4.14 galTotal distance = 0.21 miAvg. Speed = 5.95 mph
