Paper ICMPA044 8th International Conference on Managing Pavement Assets DISTRESS DATA COLLECTION QUALITY MANAGEMENT IN A REGIONAL AGENCY

The Metropolitan Transportation Commission (MTC) of the San Francisco Bay Area has supported the StreetSaver © pavement management program for local agencies for more than twenty years. For more than twelve years, MTC has administered the Pavement Management Technical Assistance Program (P-TAP) to provide Bay Area jurisdictions assistance in implementing and continuous operation of their pavement management programs. MTC selects consultants that will assist the local agencies and manages the contracts. Most of these contracts include collecting network-level pavement condition data, entering that data into the local agencies ’ databases in the MTC StreetSaver © software, and calculating the pavement condition index (PCI) values. To ensure that the data collected through the data collection contracts provide the accuracy, precision, and resolution needed for network level analysis, MTC has begun a staged implementation of an improved pavement distress data quality management plan. The first phase was prequalification of potential data collection contractors during 2009 and 2010. A number of lessons were learned in this process, and they will be used to improve future prequalification efforts. To ensure that the data collected during the network-level distress data collection is reasonably accurate at the desired resolution and precision, other components of a data quality management plan are needed including a quality control plan prepared and executed by each data collection contractor and a data acceptance plan executed by MTC.
