SiWIM® system is an efficient preselection tool to scan vehicle axle loadings before sending the likely offenders to the static weighing or low-speed WIM stations.
Its advantage over the pavement WIM systems is that it is suitable for temporary installations, particularly if static weighing campaign is also of a temporary nature. SiWIM® identifies the potentially violating vehicle and sends weighing results to the enforcement unit, together with the photo of the vehicle and its license plate (if an appropriate camera is installed).
Reduction of total number of vehicles required to stop for enforcement purposes.
Growth in domestic and international commerce.
The significant growth in domestic and international commerce has resulted in growing number of overloaded vehicles that are damaging the infrastructure and are harming the fair competition in freight transport. Challenge arises for the ability of industry to move freight economically without using larger and heavier loads. The challenge of limited enforcement resources for monitoring vehicle size and weight compliance in the interest of infrastructure preservation can be solved with the use of the SiWIM® system for preselection.
SiWIM System for scheduling Police activities.
SiWIM® System can be used for scheduling time and location of mobile enforcement missions, screening for undeclared special transports and speeding up border procedures. The system mobility allows multiple locations to be covered in a short time.
Data is used for:
- Calculation of the traffic pattern for enforcement.
- Hourly analysis of heavy traffic.
- Traffic flow analysis with ESAL calculations.
- Analysis of overflow of freight vehicles on parallel roads.
- Avoiding traffic control or tolling.
- Dangerous goods transportation analysis.
In most countries, fining of overloaded vehicles is still only possible as an result of static weighing, on permanent weighing stations or with portable weighing setups, and with the assistance of the police. As the static weighing process is very slow, weighing all vehicles and intercepting most offenders on heavy traffic roads is not feasible as it would cause tremendous queues. Therefore, to be efficient, static weighing stations must be coupled with a high-speed WIM preselection device that provides a good indication of potentially overloaded vehicles that should be checked statically. Otherwise, the truck drivers find a way to escape weighing and only a relatively small amount of offenders caught.

It can be used on country borders to identify loaded vehicles in the traffic flow for border inspection by both border and customs officers.
