Cestel d.o.o.Advanced Traffic And Bridge Management Solutions

CESTEL ltd was established in 1992 as a result of restructuring of a privately owned company Elektronika Brozovič. We have been an important part of the road engineering business ever since 1978, the year when former Yugoslavia witnessed the introduction of automatic traffic counters. We have acquired building in, instalment, subsequent servicing and maintenance of SBH-2000 traffic counters as well as developed software for data transfer and processing.

Ever since 1985 we have maintained and calibrated axle load digital scales and in cooperation with Mr Matija Kodrič from Institute for Metal Constructions and Prof. Nikolaj Zimic from Faculty of Computer and Information Science developed new electronics for Swedish-made TELUB STATHMOS portable scales. We have completely refurbished more than 50 scales.

Since 1997 we have carried out axle loads, gross vehicle weight and freight vehicles measurements and since 2005 oversight of special transport in the Republic of Slovenia. We are a sole distributor for Haeni Instruments Inc, a Swiss weighing equipment producer.

Since 1999 in partnership with Slovenian National Building and Civil Engineering Institute we have developed a system of dynamic weigh-in-motion – SiWIM. Its production started in 2001, and ever since our products have been present in Europe, North and South America and Asia. We are a leading world producer of bridge weigh-in-motion systems.
