Various devices that qualify as lightweight profilers were evaluated as part of a FHWA cooperative partnership with nine states. Connecticut offered the opportunity to seven companies to showcase their equipment. Five vendors accepted this offer, four golf-cart type devices and one hitch mounted device were evaluated. In addition, ConnDOT ran its two ARAN vehicles and an ARRB TR Walking Profiler over three test sections used for the study. All data were collected between July 7 and October 19, 1999. This report summarizes the data collection and analysis efforts. An analysis of repeatability (precision) is included. Comparisons of the lightweight profilers with the ConnDOT ARAN and the Walking Profiler are also made.
