A characteristic feature of these systems is utilising there data fusion methods. This way a possibility has been created of linking the knowledge of measuring with an initial knowledge on the measurement object. The authors have shown that these methods allow to decrease measurement uncertainty, increase measurement reliability or limit the influence of the disturbing factors.

Up to now, strip piezoelectric sensors and video systems have been used. The use of very cheap inductive loop detectors for vehicle classification is also possible. Such vehicle classification systems are based on magnetic profiles recorded from inductive loops. The magnetic profile is
The first weigh-in-motion (WIM) preselection system designed, programmed and assembled in Poland ... more The first weigh-in-motion (WIM) preselection system designed, programmed and assembled in Poland came into service in April 2001. It is equipped with two strip piezoelectric sensors and one inductive loop. It can measure up to 20 tons for vehicle speeds of 25-100 km/h. The system can estimate single axle and whole vehicle loads, vehicle speed, number of axles and distance between successive axles. The WIM system is located on the A-4, approximately 60 km from Krakow. Details are given of the weighing process and calibration process. The time distribution of the average load of all vehicles, two-axle and five-axle vehicles is described. This shows that there are more overloaded vehicles on the road during the two hours before and after midnight.

The infrastructure and condition of Polish roads isn't god, than appears necessity to protect them. One of possibiLities is to control the vehicle overloading. Up to now six weighing sites are installed in Poland. The sites consists of static scaLe and preseLection systems for each direction. UnfortunateLy the preseLection systems equipped with capacitive sensors are damage after a few month. Than the first Weighing in Motion - WIM preselection system, fully designed, programmed and assembled in Poland, has been put into service in ApriL 2001. The system operates in standard configuration, i.e. it is equipped with two strip piezoelectric sensors and one inductive loop located between them. Each axle is weighed twice due to the empLoyment of two WIM sensors. The arithmetic mean vaLue of both results is assumed as the final axle load. The measuring range of the system ...

The proposed method for a moving passenger car load estimation is capable of detecting an overweight vehicle, and thus it finds its application in road safety improvement. The weight of a car’s load entering or leaving a considered zone, e.g., industrial facility, a state, etc., is also of concern in many applications, e.g., surveillance. Dedicated vehicle weight-in-motion measurement systems generally use expensive load sensors that also require deep intervention in the road while being installed and also are calibrated only for heavy trucks. In this paper, a vehicle magnetic profile (VMP) is used for defining a load parameter proportional to the passenger vehicle load. The usefulness of the proposed load parameter is experimentally demonstrated in field tests. The sensitivity of the VMP to the load change results from the fact that the higher load decreases the vehicle clearance valu...

Equally expensive are the consequences of not ensuring adequate road safety. This creates the need for an efficient and automatic system for the detection of overloaded vehicles [17]. One of the tools designed to measure the weight and individual axle loads of vehicles are the systems weighing vehicles in motion (WIM). Due to their measurement imprecision, WIM systems composed of two lines of sensors are only used as pre-selection systems. At present, the only viable option for reducing measurement uncertainty in dynamic weighing is to increase number of load sensors (Multi-Sensor systems; MS-WIM). The paper presents the results of research on a MS-WIM system equipped with 16 lines of load sensors. The conceptual objectives, system design, results of experimental evaluation of the system's accuracy, and the final conclusions based on a 6-year operating period, during which the system has been used under normal traffic conditions have been presented.

This system was designed in Poland in a period of 3 years from 2003 to 2006. The embodied system is equipped with 16 piezoelectric load sensors, in the form of narrow 4m long strips, provided by Measurement Specialties. The paper outlines the system structure and its elements i.e. the weighing site, the data acquisition system and data processing software. Experimental tests indicate that the designed MS-WIM system falls in accuracy class B+(7) in the speed range from 30 km/h to 80 km/h.
