DEPARTMENT OF TRANSPORTATION Bureau of Maintenance and Operations; Standards and Methodology for Data Collection [29 Pa.B. 1129] The Department of Transportation, Bureau of Maintenance and Operations, by this notice and consistent with the provisions of § 9104 of the Vehicle Code (75 Pa.C.S. § 9104), hereby establishes the standards and methodology for data collection used in the calculation of the Relative Pavement Quality index (RPQ). The PRQ is based upon the Road Quality Report which entails the evaluation of the conditions of the highways in each county on a periodic basis.
