Recent research and analyses have identified several issues regarding the quality of traffic data available from intelligent transportation systems for transportation operations, planning, or other functions. The Federal Highway Administration (FHWA) is developing an action plan to assist stakeholders in addressing traffic data quality issues. Regional stakeholder workshops and white papers will serve as the basis for this action plan. As one of those white papers, we reviewed current and advanced practices for addressing data quality in three types of user communities: 1) real-time traffic data collection and dissemination; 2) historical traffic data collection and monitoring; and 3) other industries such as data warehousing, management information systems, and geospatial data sharing. The recommendations in this paper follow from this review. |
