Measuring system with three inductive loops

The module uses two narrow (10 cm) and one wide inductive sensors. The narrow sensors act as axis detectors. A significant advantage of this solution is the much lower cost of inductive sensors compared to polymer axis detectors. Required module: 3 loops – module working with three inductive loops Required sensors: three inductive loops

Module: 3 loops

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,
• length measurement,
• number of axles,
• distances between axles,
• classification by length (4 classes of vehicles 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).
