Underinflated or overinflated tyres have an increased risk of a blowout and potential accidents, have a negative effect on fuel consumption and will increase tyre wear. Incorrectly inflated tyres are not easy to detect by visual inspection particularly as inner tyres aren’t easily visible. Low speed WIM or SIM measurements can be used to check the tyre pressure, wheel loads, axle loads and vehicle weight. In case a potential problem is detected, the driver or fleet manager of the truck can be notified. This results in lower running costs, increased traffic safety and an extended tyre life.
Historic bridges are generally designed and built in a time where heavy good vehicles were much lighter or did not exist at all. These bridges often still serve as part of the modern road transport network, at the same time they may have an important historic and cultural value to society. A WIM system can detect an overloaded vehicle before it crosses such bridges or enters the historic center of a city. This avoids unnecessary damage, reduces maintenance cost and helps to protect cultural heritage sites.
Traffic and transportation management
Real time monitoring of the actual traffic flow on a road network helps to optimise traffic management. WIM systems are able to deliver automatic and detailed real time traffic management information 24/7 without disrupting the traffic flow. Detailed information on the traffic flow road also provides an important input for transportation studies that help transport authorities to optimise the planning and design of the future road network.
WIM systems will also detect not only overloading but also under loading, hence vehicles driving unloaded or partially loaded. Data from WIM systems may help governments to develop policies that improve the efficiency of the freight transport as a whole. On-board WIM systems may be used by transportation companies to maximise the loading of each individual vehicle and the efficiency of their logistic process as a whole.
For these applications low speed WIM systems are generally used. They are more efficient than the static scales as they significantly reduce the measurement time and provide higher throughput of measured vehicles per hour.
At (sea) ports
At sea ports, LS-WIM systems are used in controlling the entries and exits of terminals. The WIM system can check the weight of all the cargo (containers) being loaded onto a ship to optimise the load distribution over the ship or controlling the loading of heavy vehicles on the ferries. At the same time, the correct loading of the trucks that transport cargo from the port can be checked.
At industrial or logistic plants
Likewise, the WIM systems can be used to check the weights and axle loads of trucks leaving the plant and prevent overloading before the trucks enter the road network.
If the WIM systems are certified for trade applications, they can also be used for the invoicing of industrial (bulk) goods by weight.
