INDUCTIVE TRAFFIC COUNTERS

Inductive traffic counters are used for presence detection, counting and classification of vehicles and speed measure- ment. Using two inductive loops in the lane detects the speed, length and the direction of passing vehicles. Based on the magnetic vehicle fingerprint, vehicles are classified in 8+1 vehicle categories. The basic version of the traffic counters covers two traffic lanes and is appropriate for the level of national roads. The concept of the device enables the extension of counting up to 32 lanes, and the device is also suitable for large intersections. The device supports three modes of operation with regard to the establishment of communication.

TECHNICAL CHARACTERISTICS

The first is a periodic device polling and answering at predetermined intervals, which may be revised as necessary. In the case of pre-defined alarm situations, the device is able to establish communication with a higher-level system and transmit an alarm message. Such situations are jam, speeding, loop breakage, driving in the opposite direction, and various combinations depending on the class of the detected vehicle. Apart from the alarm messages to the supervising center, the device is able, upon the occurrence of an alarm condition, to trigger the nearby devices, such as traffic cameras. The third mode of communication is designed for applications in intelligent traffic management systems, where the device can be configured to continuously forward data to the local or supervising management center.

The device can be connected to the central control and monitoring system based on the eNvision™ aplication platform.
