Weigh-in-motion or weighing in motion (WIM) devices are designed to capture and record axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a stop. This makes the weighing process more efficient, and, in the case of commercial vehicles, allows for trucks under the weight limit to bypass static scales or inspection. ==Road applications== Especially for trucks gross vehicle and axle weight monitoring is useful in an array of applications including: * Pavement design, monitoring, and research * Bridge design, monitoring, and research * Size and weight enforcement * Legislation and regulation * Administration and planning Weigh in motion scales are often used for size and weight enforcement, such as the Federal Motor Carrier Safety Administration's Commercial Vehicle Information Systems and Networks program. Weigh-in-motion systems can be used as part of traditional roadside inspection stations, or as part of virtual inspection stations.〔(【引用サイトリンク】url=http://www.fmcsa.dot.gov/facts-research/cvisn/expanded-CVISN.htm )〕 Recent years have seen the rise of several "specialty" Weigh-in-Motion systems. One popular example is the front fork garbage truck scale. In this application, a container is weighed—while it is full—as the driver lifts, and again—while it is empty—as the container is returned to the ground. The difference between the full and empty weights is equal to the weight of the contents. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「weigh in motion」の詳細全文を読む スポンサード リンク
