This paper addresses a large-scale field test of a real-time freeway network traffic state estimator that was recently developed. The related network traffic flow modeling and state estimator design are first outlined. The test of the estimator for the A3 freeway of 100 km between Naples and Salerno in south Italy is then reported in some detail. The obtained results are deemed quite satisfactory and promising for further future implementations of this traffic state estimation tool.
