Abstract:

The provisions contained in the Federal Highways Administration's recently issued Traffic Monitoring Guide as well as the traffic data collection portion of the Long-Term Pavement Performance monitoring effort within the Strategic Highway Research Program (SHRP) require the use of automated vehicle classification for their implementation. The vehicle types specified in that document can only be identified from data acquired from axle detectors. Current traffic data collect ion practice includes only one proven axle detector technology pneumatic tubes. Unfortunately, these devices are inappropriate in. many situations. This report presents the results of an evaluation of alternative axle sensor technologies. Namely, piezoelectric ceramic cable (PZCC), piezoelectric plastic cable (PZPC), piezoelectric film (PZF), and tape switch (TSW). These sensors were tested under different environmental and load conditions. Experimental results include a characterization of the linearity and the uniformity of the response of each sensor, and a comparison of the four sensors tested.
