Traffic monitoring systems

In times of minimal rates of change in annual traffic development, the TLS A1 monitoring and classification of road traffic is becoming increasingly important. Traffic Data Systems provides the systems needed to carry out this monitoring. The introduction of the 8 lane (16 loops) TMCS-U sets  new standards in the field of counters/classifiers. These systems are also available for OEM customers.

The high accuracy of the data is based on powerful algorithms and modern pattern recognition techniques which are used to evaluate vehicle signatures (traversal curves for vehicles over inductive loops). As well as storing long-term and short-term data locally, systems of this kind can also store individual vehicle data. With the appropriate bandwidth, this data can be transmitted to sub-centres together with long-term and short-term data.

The outstanding performance features of the TMCS-U have been prooven after evaluating the results of an international test of 34 different counters/classifiers. In terms of classification it has shown its lead.

Technical Characteristics

The TMCS-U is available as a stand-alone FG1-EAK including several interfaces. The function group FG 1 outputs interval-controlled short-term and long-term traffic flow data, which are gathered and evaluated by BASt-certified inductive loop detectors/classifiers. The measuring intervals can be parameterised from a central unit or locally.

Vehicle Classes

The same learning set is used in the TMCS/TMCS-U as in the VDK 900 detector/classifier with 8+1 vehicle types certified with A1/300m by the BASt. Special learning sets are provided for customers in other countries (e.g. 10+1 classes (Denmark), SWISS 10 and NorSIKT Level 4).
