Evaluation and Implementation of the Automatic Road Analyzer (ARAN)
In 1985, the Texas State Department of Highways and Public Transportation (SDHPT) purchased a multi-functional road quality surveying system, called the Automatic Road Analyzer (ARAN), which measures several roadway conditions simultaneously, including pavement roughness, pavement transverse profile (rutting), and roadway geometrical characteristics. The report evaluates the orientation subsystem and rut depth subsystem of the ARAN unit using field tests and the resulting data. In this evaluation, the principal activities involved the evaluation of the static, dynamic, and operational performance. Static performance tests were conducted separately to test the stability, measurement specifications, and measuring accuracy of the orientation subsystem and rut depth subsystem. The dynamic performance tests of the orientation and rut depth subsystems (conducted with the ARAN unit operating under normal conditions) compare responses of the two subsystems with chosen references. The operational performance tests were conducted to check whether the subsystems are reliable under different operating conditions. A procedure characterizing the transverse profile and rutting was developed in the study.
