Traffic data ­ acquisition systems

Data gathering

In times of minimal rates of change in annual traffic development, the monitoring and classification of road traffic with accuracy class A1/300m in accordance with TLS 2012 is becoming increasingly important. Traffic Data Systems is currently the only manufacturer to offer detectors/classifiers with a valid A1/300m test certificate. The high accuracy is based on powerful algorithms and modern pattern recognition techniques which are used to evaluate vehicle signatures (traversal curves for vehicles over inductive loops). Short-term, long-term and individual vehicle data can be stored and, of course, also transmitted to sub-centres.

Along with the TMCS-IP, the TDS 820R and TDS 821R systems, which have been in operation since the beginning of the 1990s can also be brought up to the latest state-of-the-art and connected using modern detectors/classifiers and communications media (4G, AUSA, fibre optic cable).

Technical specification

Our systems are available as a stand-alone FG1-EAK with various interfaces. The function group FG1 outputs interval-controlled short-term and long-term traffic flow data, which can be parameterised from a sub-centre via a remote connection or on site.

Classifiers

The same learning set is used in the TMCS-IP as in the VDK 900 detector/classifier with 8+ 1 vehicle types certified by the BASt with A1/300m. Special learning sets are available for customers abroad (including 10+1 vehicles (Denmark), SWISS 10 and NorSIKT Level 4).
