A key feature is the embedded system intelligence enabling the system to efficiently support critical traffic conditions such as recognising stationary and queued vehicles as well as slow moving queues.
In addition, automatic vehicle detection guarantees a detection rate of 99.5 per cent of all passing vehicles, and the accuracy at high-vehicle throughput, such as on busy highways, is outstanding. Tattile says its axle counter can count up to 2,400 vehicles per hour and a peak of one vehicle per second for up to 60 seconds in extreme dense traffic periods. The maximum vehicle speed for correct measurement is 250km/h.
Another feature of the axle counting system is the identification of a raised axle due to the light load of a vehicle. The system can also support the use of two independent external devices to ensure left sight and right sight. An IR illuminator allows day and night operation while data output is provided as the reconstructed image of the vehicle and configurable metadata. Data can be sent to a server or stored locally and web access to the system is possible with credentials.
Tattile states that the combination of all these features drives vehicle axle counting to perfection.
