Quality Review and Assessment of Pavement Condition Survey Vehicle Data Across New England

The New England Transportation Consortium (NETC) members spend significant time and resources on pavement surface condition data collection in support of a wide range of reporting and decision-making functions. Quality data are of critical importance to these functions—as the adage goes, “garbage in, garbage out.” The data quality management plans (DQMPs) mandated by Congress in 23 CFR 490.319(c) provide a means to assist in achieving quality data, but the specific steps are not clear. This project was undertaken to provide data collection quality guidance. A review of the existing NETC member DQMPs was first undertaken to better understand their strengths and weaknesses. Interviews with NETC member agency staff were then conducted, with a focus on the identification and selection of control sites needed to establish the reference values for the certification, validation, and verification of pavement surface data collection equipment. The resulting information was used to develop common terminology to facilitate clear and concise communications between NETC members; guidelines and tool for the identification and selection of control sites, which consider site requirements and characteristics; recommendations for control site inter-agency sharing options; and other data quality-related guidelines, such as certification, validation, and verification frequency. Once implemented, the terminology and guidelines will yield important benefits to the NETC members.
