As with many technological advances, developing the dynamic scale has been difficult. When the scale finally proved accurate for trucks traveling 40 miles per hour, it would not perform for trucks traveling at higher speeds. However, eight months ago, Stanley announced that the dynamic scale was ready to be field-tested by the Nebraska State Department of Transportation under a grant from the federal government. Stanley explained to his financial partners, and to Nebraska transportation officials, that the dynamic weight would not exactly equal the static weight (truck weight on a static scale). However, he was sure a statistical relationship between dynamic weight andstatic weight could be determined, which would make the dynamic scale useful. Nebraska officials, along with people from Dynamic Weigh-ing, installed a dynamic scale on a major highway in Nebraska. Each month for six months, data were collected for a random sample of trucks weighed on both the dynamic scale and a static scale. Table 15.3 presents these data. Once the data were collected, the next step was to determine whether, based on this test, the dynamic scale measurements could be used to predict static weights. A complete report will be submitted to the U.S. government and to Dynamic Weighing.
