Descriptive nameAutomatic Road Analyzer(ARAN) van major road GPS points collected 2009
File namestvm2009
Spatial domainPima County
AbstractAs the van is driven, a data point is captured every 26.4 feet by GPS, along with 2 image frames for each point. International Roughness Index (IRI) and Pavement Surface Evaluation and Rating (PASER) data is attributed to each data point, with IRI automatically captured by a sensor, and PASER data input by the van personnel. Data points are captured from driving in both directions, when not driving on a one-way road, therefore data points are available for both sides of a road.
Known errors/qualificationsAll major roads captured in 2009.

LineagePCDOT pavement management (PM) data is stored and retrieved from the CarteGraph system. The PM data is stored by road segment within CarteGraph, and brought into the GIS through the implementation of a Linear Referencing System (LRS)/Dynamic Segmentation (DynSeg). An LRS/DynSeg allows the PM data to be integrated into the GIS without the need to modify the underlying geometry of the road network. The GIS road network's geometry is segmented from intersection to intersection, and PM segments can span multiple GIS segments and/or stop and begin at a distance that is offset from an intersection.
