Pennsylvania Department of Transportation has been a long standing client of Roadware for its roadway data collection requirement. Since 1997, Roadware has been providing pavement, georeferencing, geometric and distress data, as well as right-of-way videologging and inventory of roadway assets on 27,000 miles of PennDOT’s road network every year.
The client selected Roadware as its data collection contractor at a time when it was seeking to expand the use of automated data collection processes to provide more accurate, repeatable information to enhance the DOT’s pavement management program. Roadware’s ARAN data collection system, our commitment to producing quality data on time, and our willingness to work with the client to tailor our processes to their requirements has resulted in this long time partnership with PennDOT, helping to achieve their pavement mangement program goals.
Details of the data collected for this project are:
- Longitudinal profile in each wheel-path and calculated IRI
- Transverse profile (rutting) for each wheel-path separately
Georeferencing and Geometric Data
- Differential GPS and distance as references for all measurements and reports
- Surface distress data and pavement video, processed using Roadware’s WiseCrax Automated Distress Analysis System and Roadware’s DV-Rate semi-automated method
Right-of-Way Videologging and Asset Inventory
- Panoramic digital video - three forward facing cameras (1,300 x 1,030 pixel resolution stored in JPEG format, on a 21.12 foot (4 millimile) interval)
- ROW images combined with pavement data and displayed using Roadare’s VisiData image display software throughout all eleven PennDOT District offices.
- Roadware’s Surveyor™ asset inventory software used with ROW video images to create a guiderail inventory (location, offset of guiderail endpoints, linear location, type of end treatment, condition of guiderails)
- In 2003, PennDOT added edge drop-off detection to the scope of the project. Roadware’s recently introduced Laser XVP automatically detects shoulder edge drop-off and reports the location of areas that need repair. Also, in addition to using VisiData software, PennDOT implemented a GIS-based video web viewer to allow viewing of data and images across the organization.
