Center and all of the equipment owned or leased by ORNL was returned. 3.3.6 Task 6: Test and Evaluate the Instrumented Tractor-Trailer (Collect Pilot Data). Pilot Testing was originally scheduled to have begun in early August, 2005. Because of various delays related to staff engineer availability, availability of equipment, and equipment calibration, pilot testing was not initiated until October 23, 2005. Because of this delay, and because of the need to expedite A-22
initiation of pilot testing, a request was made to Mr. Lee Slezak for his agreement not to engage in the open house for the instrumented truck as originally planned. Several alternatives to conducting the “open house” were suggested including a suggestion to display the Dana Technology Truck outfitted with Pilot Test data instrumentation at the SAE Government-Industry Meeting in the Washington DC area in May 2006. Figure 28: Trailer Ballast From Mid- Trailer to Nose of Trailer Figure 30: VBOXII Prior to the Loading of the Ballast Figure 29: Trailer Ballast From Rear to Nose of Trailer Figure 31: WXT510 Weather Station Mounted on Side Mirror Pilot Testing took place from October 23, 2005 through January 19, 2006. This period of time included the holidays and involved considerable bad weather that caused some additional delays. The map in Figure 32 shows the East-West route, and Figures 33 and 34 show the North-South route (the route traveling South, and the route traveling North respectively). Each route was traveled twice (once with standard dual tires and once with new-generation single tires). It should be noted that the routes taken were not strictly identical, but were very similar. Two Chicago-to-Portland roundtrip runs were made between October 23, 2005 and November 19, 2005. For the first dataset (collected during the period October 23 rd - November 2 nd 2005), the truck was mounted with regular dual tires; for the second (November 7 th – November 18 th 2005) it had new generation singles. During the two round trips 8,500 miles were covered and 220 hours of driving were logged. More than 24 Gigabits of data were collected and saved to A-23
