SW2224 DETECTOR

SWARCO loop detector for vehicles detection with classification and speed measurement for traffic data acquisition and traffic management.

SW2224 CLASSIFICATION DETECTOR

The SW2224 operates with two induction loops per lane, in accordance with ASTRA-SWISS specification. Based on the proven and tested MC2024 / CD9054, the detector uses state-
of-the-art measurement methods for highest classification accuracy and detection speed.

FEATURES

• Acquisition of traffic data in accordance with ASTRA¹  for 2 lanes with speed and length measurement, detection of direction and wrong way drivers with double loop systems, occupancy rate in connection with a controller

EASY OPERATION

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 SW2224 classifies the vehicles in ASTRA-SWISS classes (SWISS 10, SSVZ or car-similar/HGV-similar vehicles). When ASTRA-SWISS loops are used, the classification meets the accuracies required by the ASTRA 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.

Via the RS485 bus single-vehicle data is transferred to a controller, which takes over further data aggregation acc. to ASTRA specification. 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 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 Swiss federal roads office.
