Classification and Speed Measurement

MC2224 DETECTOR Classification and Speed Measurement

The MC2224 loop detector was specifically designed for vehicle detection with classification and speed measurement for traffic data acauisition and traffic control.


The MC2224 is a classification detector, operating with two induction loops per lane, in accordance with TLS*-specification. Based on the proven and tested MC2024 / CD9054 the usages of powerful 32-Bit controllers allow the improvement of all features such as classification accuracy, power consumption, as well as the function range.

The MC2224 classifies the vehicles in (8+1), (5+1) or 2 classes acc. to TLS. When TLS loops are used, the classification meets the accuracies required by the German federal highway research institute and is not influenced by e.g. weather conditions. On activation of the directional logic, reports of wrong way drivers can be generated. The vehicle type is determined by means of passing-curves which have characteristic features depending on the different classes and the loop types used.

*TLS: Technical delivery terms for roadway stations

Via the RS485 bus single-vehicle data is transferred to a controller, which takes over further data aggregation acc. to TLS-specifications. The detector automatically adjusts itself to the attached loop/feed-cable combination. Variations in temperature have no influence on data acquisition.

The measuring systems are permanently checked for short or open loops, only when a definite malfunction is detected, systems are put into a failure condition. If one loop of a TLS double-loop system is disturbed, the remaining loop supplies further data on time of occupancy, time gap and a classification of car-similar and HGV-similar vehicles.

Speeds and vehicle lengths cannot be determined. Short measuring intervals and a new procedure for speed measurement provide for the high accuracy of the measured data and the high detection speed, according to the requirements of the German federal highway research institute.

The LoopMaster operating program, which is available free of charge, offers extensive loop and detector analysis functions. The trend-setting customizing allows an individual configuration and setting of operating elements and functions.

The detector can provide the following single-vehicle data via the RS485 interface, depending on the TLS classification version:
