Measurements of Road Traffic Parameters Using Inductive Loops and Piezoelectric Sensors

Piotr Burnos

The basic problems corresponding to the traffic measurements have been presented in the paper. Authors gave the general overview of the parameters and characteristics describing the vehicles and traffic flow. The current sensors’ technologies used in measuring systems has been presented. Moreover the measuring systems used in traffic measurements have been described. Special attention has been paid to the more sophisticated problems like the vehicle’s classification based on the analysis of its magnetic signature and to vehicles’ weigh-in-motion technique. The presented results base on the Authors’ experience in designing and exploitation of the measuring systems equipped with inductive loops and piezoelectric sensors.
