Measuring system with a single induction loop

Measured parameters:

• vehicle arrival time (with 0.01s resolution),
• vehicle counts,
• 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).
