摘要：	An analysis has been made of weigh-in-motion (WIM) data that were collected by continuously operating systems at three different sites on the same route. The analysis examined the gross weight distribution of 5-axle tractor-semitrailers. Each direction had its own unique pattern. The eastbound 5-axle tractor-semitrailers were predominantly loaded and showed a similar pattern at all three WIM stations. The westbound 5-axle tractor-semitrailers were predominantly empty and showed the same pattern at the three WIM stations. One result of these consistent patterns at the three WIM stations is that, as a minimum, on selected routes where long-haul loading characteristics (origin-destination, commodities hauled, etc.) are known, data users, such as forecasters, can confidently use weight data collected at one location and apply it to another location on that route. A second result is that these repeating patterns make it possible to monitor the calibration of WIM systems. When a shift in the weight distribution takes place at one site while remaining constant at the other two, it indicates a possible change in calibration. These changes in calibration are readily observable. The techniques demonstrated here can also be used to analyze data collected at WIM sites that may be distant from other WIM sites.
