| 摘要： | The Texas Department of Transportation (TxDOT) has been using a five-sensor rut bar system, implemented with ultrasonic sensor technology, to automatically collect estimates of pavement rutting for PMIS purposes. A number of problems occur when using the acoustic sensors for this purpose. During TxDOT Project 1782 a set of procedures were developed for using the Acuity AccuRange 4000 laser system for measuring rut. At the end of the project it was recommended that the use of the system be implemented on a larger sample of roads. Following this project, TxDOT initiated an implementation project with the University of Texas at Arlington in December of 2002. This current report discusses the implementation effort. |
