Description | Status: COMPLETED 2005. Original x.y data stored in Microsoft Access database (pms_van.mdb) on MapGuide server Contact: Todd Kessler, TDOT Pavement Management Staff, 520-791-3154, Todd.Kessler@tucsonaz.gov Intended Use: For map display and as starting point for the ARAN virtual ride application http://www.transview.org/aran/ Supplemental Information: An ARAN is a specially modified vehicle that houses an extensive set of sensors (including laser reflectometers, ultrasonic sensors, accelerometers, global positioning systems, gyroscopes, video and machine vision systems) and computers, along with other highly advanced technology subsystems. The purpose of all this technology is to provide transportation departments with information about their roadways and right-of ways, including their condition and the location of specific features and/or faults. This data is critical to the management decision process that involves billions of dollars of assets, and maintenance budgets of millions of dollars each year. An ARAN provides information to support better management decisions by collecting consistent, accurate, data quickly and cost effectively. It is capable of measuring up to 15 different data items in a single pass, with very high accuracy. This data can be collected continuously, at traffic speeds from 15 mph up to highway speeds. Some of the information that can be collected includes: -The ride quality of the roadway [longitudinal profile / roughness (IRI)] -The wearing of the roadway in the wheel paths [rutting] -The grade and cross-slope of the roadway -Real time video imagery of the roadway pavement and right-of-way imagery -Precise location information of specific features on or near the roadway -Faulting of concrete pavements |
