- 21. 10:31 a.m. June 10th, 2009 Mile Post: 31 Track Vegetation Sprayed NPDES Compliance Tool • NPDES permits are required to treat “on or near” waters of the U.S. • High accuracy application mapping shows which areas were treated 2009 Perceptive Robotics, LLC
- 22. Avoiding drift & documenting wind speed • Ultrasonic wind-meter provides accurate measurements of wind speed every second while moving. • Document that wind-speed complied with drift regulations. • Set wind-speed warning thresholds for normal operation and ecologically sensitive areas • Import warnings from sites like driftwatch.org
- 24. Example of Information Driven Efficiency • Speed = amount of herbicide applied – Each nozzle size is designed for a particular speed • Too fast Under spray area • Too slow Over spray area • How much is application speed costing us? – Or how are results suffering from under- applying? • Are our nozzles the right size?
- 25. Actual application speed How much is application speed wasting? $4/acre (10% of total) Design Speeds Actual Speeds 2009 Perceptive Robotics, LLC
- 26. What’s Next • Long-term monitoring of herbicide application and weed pressure – When to treat? – What to use?
- 27. What’s Next? • Crossing visibility analysis: • Track condition monitoring

Editor's Notes
- Talk about relationship with Jerry and how over the past 2 years you’ve identified key aspects of the spraying industry that technology can address
- Gerry has been telling me about the problems facing the railroad vegetation control industry
- Key capability to improve IPM is selective spraying, consisting ofKey ideas:Full area automatic weed detection & spray controlControl over how much vegetation required to activate each zone.Easy to verify correct performance (Weedseekers hard to adjust)
