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

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
