• Abstract:
  In 1992 the Oregon Department of Transportation undertook an operational test of the Port-of-Entry Advanced Sorting System (PASS), ; which uses a two-way communication automatic vehicle identification system, integrated with weigh-in-motion, automatic vehicle ; classification, and over-height detection tied into a heavy vehicle database. The purpose of this operational test was to demonstrate the ; feasibility of using this system to let trucks directly bypass the port and the static scale weighing process, thus resulting in significant ; benefits for both the carriers and the State. An additional purpose was to test the use of ?double-threshold? bending plate type weigh-in- ; motion scales to improve the weighing accuracy as compared to single weigh-in-motion scales. In this Final Report, the authors describe ; the PASS system and present results obtained from three years of operation. Results from a survey of trucking firms are presented. ; Results from the testing of the double-threshold weigh-in-motion scales are also presented and discussed. ; Some problems with the state-of-the-art PASS occurred, causing interruptions. Most were software problems, which were resolved. The ; survey indicated that truckers and trucking firms using the two-way transponders were pleased with the system. The project proved that the ; mainline sorting of heavy vehicles to bypass or enter a Port-of-Entry is workable with current technology. ; The variability of weight measurements using the double-threshold weigh-in-motion scales was found to be less than the variability of ; measurements from the twin weigh-in-motion scales when taken separately. Unfortunately, the weights provided by the WIM scales ; appeared to be biased toward the mean in spite of careful calibration. Thus the value of double-threshold WIM scales remains unclear. 38 p.
