Task 11: Support ANL in PSAT Efforts Task 12: Prepare Phase 2 Report with Recommendations for Future Efforts. Task 13: De-Instrument Vehicles, or Plan for Phase 3. 5.0 CONCLUSIONS The efforts engaged in during Pilot Testing were extremely valuable. Failure to invest in pilot testing activities prior to a field test has a strong potential for having something go wrong during the field test. Field hardening of instrumentation or data collection systems, familiarity with such instrumentation and systems, optimal calibration, and just generally pilot testing lessons learned, protocols and procedures are ways of ensuring that once a field test has been initiated, that downtime is kept to a minimum. The HVDC team obtained considerable experience with the sensors and data acquisition systems utilized during the pilot test. A more optimal data collection frequency rate was determined, and attention was focused on the need for better time stamping and data synchronicity. Additional emphasis in field test design is being placed on the need for continually-mated tractor trailers. Because of this, more than one volunteer fleet may need to be utilized The handling of the enormous amount of data that was generated in the Pilot Test was discovered to be very resource intensive. The adjustment of data collection rates, the collection of data at the same frequency for all performance measures, and the need to develop some automated data handling/management tools were identified to be necessary and will be addressed in the field test. Overall, the conduct of the pilot test resulted in the HVDC team to be much more prepared for the conduct of the field test, in the analysis of the data generated and in envisioning capabilities for providing tools for generating custom duty cycle profiles and information.
