Single induction loop +2 axis detectors

Measurement system equipped with a single induction loop and two polymer axis detectors

 Equipping the system with two axle detectors allows to use a different algorithm of vehicle speed measurement. This allows to reduce the uncertainty of the determination of this parameter and its derivatives.
Required module:
axle detector – a module that works with a single inductive loop and two polymer axle detectors
Required sensors:
one induction loop
Two polymer axis detectors
Moduł: det. osi
Module: axis detector

Measured parameters:

  • vehicle arrival time (with 0.01s resolution),
  • vehicle counts,
  • interval between vehicles (0. 01s resolution),
  • magnetic profile and vehicle classification based on it
    (4 classes are distinguished: cars, vans, trucks, buses)
  • trailer detection,
  • speed measurement (measurement error <1 km/h),
  • length measurement (measurement error 2%),
  • number of axles,
  • distances between axles,
  • classification by length (4 vehicle classes are distinguished),
  • FHWA F or ALT classification,

Determined characteristics (variation as a function of time):

  • traffic density,
  • flow (of vehicles),
  • lane occupancy,
  • average speed,
  • number of vehicles by class (according to selected classification scheme).
