The FHWA Roadway Data Improvement Program (RDIP) offers assistance from national subject matter experts (SME) to States, local roadway owners, and Tribal data stakeholders. The RDIP can provide roadway data training, recommend opportunities for enhancing data and analysis systems, and improve interagency coordination and communication. The RDIP has assisted 15 State agencies to review and improve their roadway data programs since its introduction in 2013 (see map). States may request RDIP assistance from the FHWA Office of Safety at any time.
Although the program has a roadway safety data focus, the RDIP often reviews data sets and procedures related to roadway and intersection inventories, crash data, traffic monitoring and operations data, construction project records, roadway and roadside asset data, data security and accessibility, and data quality management.
