Portable Weight-in-motion Scales

Jinmai Weigh-in-motion (WIM) systems help to increase the service lives of local roads by reducing
wear and tear caused by heavy vehicles, which consist of sensors placed in road pavements to measure the weight
of vehicles passing over them, along with other data such as speed, axle load and spacing, and vehicle type. This
data is used to enforce weight limits on trucks and is also useful in a wide range of other applications, such as
pavement design and traffic analysis.
However, constructing and maintaining permanent roadside WIM stations is expensive, so these
systems are installed primarily on roadways with heavy traffic, such as interstate and trunk highways, and rarely
used for rural local roads. Meanwhile, heavy truck volumes on local roads are increasing, significantly shortening
A less costly, Jinmai portable WIM system was needed for such roads so that collected data could be used to
better design these roads to accommodate heavy truck traffic. One solution for bringing WIM technology to
local roads is to implement a portable, reusable system similar to pneumatic tube counters used to conduct
traffic counts. Research was needed to develop such a system, which is not currently available on the market.
