Stahl Sheaffer was selected to assist Penn State in completing a Location Reference System (LRS), a condition analysis, and a priority maintenance planning tool for all roads on the University Park campus and surrounding satellite properties. Stahl Sheaffer conducted a 3-D LiDAR survey of more than 100 miles of roadway, including surface conditions, curb locations and attributes, sidewalks and ramps, bus pull off areas, sight distance at intersections, and other attributes for both paved and unpaved roads. The survey resulted in collection and storage of LiDAR point cloud survey data, 360° imagery, and high-definition video logs for 312 roadway segments.

The data was used to develop a campus-wide roadway classification system and a Roadway Network Maintenance and Repair Prioritization Tool to provide Penn State with a process to systematically identify and prioritize necessary repairs, maintenance, and rehabilitation as well as to forecast yearly expenditures. The tool produces a list of prescribed anticipated standard roadway maintenance and repair options using:
· The current condition of the roadways.
· A deterioration model developed for this project.
· Roadway prioritization criteria based on criticality.
· Standard maintenance and repair options.
The tool is designed to adjust repair recommendations and costs over a 20-year period as updated Pavement Condition Index (PCI) assessments, repairs, and/or budget numbers are entered. Prescribed maintenance and repair options within the 20-year maintenance schedule can be changed as necessary by clicking the drop-down arrow and selecting a desired option.

The Roadway Network Maintenance and Repair Priority Tool also estimates construction costs associated with the prescribed maintenance and repair options as well as the anticipated effect on the roadway’s surface rating (PCI). The tool can be used to:
A. Set a budget based on desired health of the roadway network.
B. Show roadway health over time based on a set annual budget.

All data for the tool is maintained in a file geodatabase format and in excel files for direct import into Penn State’s asset management program and ArcGIS. Ongoing evaluations in the field will ensure conditions are updated and accurate.
The Maintenance and Repair Prioritization Tool allows roadway maintenance to be considered when planning for other construction projects on campus. With a timeframe for when any given roadway in the Penn State roadway network will need to be addressed, all departments can coordinate to organize construction projects in the most cost effective and efficient way.
The initial project was implemented at University Park and its satellite locations but rolled out to include 258 miles of roadway and approximately 600 parking lots at 23 campuses across the Commonwealth.
