Measuring system equipped with a single induction loop

The use of a single induction loop is an unusual solution. It should be seen as a cost-saving solution, used for example when using an already installed sensor used for other purposes.

Required module:
1 loop – measurement module working with a single inductive loop

Required sensors:
induction loop

Measured parameters:

• vehicle arrival time (with 0.01s resolution),
• vehicle count,
• interval between vehicles (0. 01s),
• magnetic profile and vehicle classification based on it
  (4 classes are distinguished: passenger cars, vans, trucks, buses)
• trailer detection,
• speed measurement (single-loop) (measurement error from 5% for passenger vehicles to 18% for trucks),
• length measurement (measurement error up to 20%),
• classification by length (4 vehicle classes are distinguished).

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).
