Estimating Measurement Uncertainty of Traffic Monitoring Systems

All the more advanced traffic management techniques base their efficiency on reliable traffic monitoring systems. In a so important and emerging field, where the technical solutions proposed to measure and collect traffic primary data are not few, a unique methodology to evaluate and compare their performance still misses. In the paper the problem of the metrological characterization of traffic monitoring systems is widely treated, founding inspiration on the ISO guide to uncertainty in measurement. Early experimental results are reported to demonstrate the applicability of the suggested procedure to some off the shelf instruments.
