Abstract (en)
[origin: EP1480182A2] Contactless axle counting system for road transport has at least a measurement arrangement (1) for measuring changes in environmental parameters such as sound, temperature or vibrations caused by the tires of a vehicle passing near the measurement area. The measurement arrangement is placed at or near the contact point of the vehicle tires on the road surface. The measurement arrangement can be positioned above the road surface, e.g. in an existing bridge or overhead gantry. Suitable measurement arrangements can be based on laser-vibrometers or directional microphone systems.
