Abstract:The MAP-21/FAST Act requires state departments of transportation to transition to data driven, performance and outcome-based programming, which has required states across the nation to revisit their data collection and maintenance efforts. This report documents research to ensure that the future SCDOT database specifications and data collection efforts support federal requirements for data-driven performance-based management of transportation facilities, as well as meet the needs of SCDOT in a cost-effective manner. To achieve this goal, three specific objectives were established: 1) Identify SCDOT state of practice for asset data collection and maintenance; 2) Conduct vendor rodeo and determine accuracy and cost effectiveness of mobile asset data collection; and 3) Provide specifications for database development and related data collection methods and/or technologies to respond to MAP-21 and SCDOT requirements. Three main recommendations include: 1) Raise the level of importance of data – treat it as an asset, define core principles, and develop a department-wide directive that recognizes the strategic uses of data across all business offices; 2) Implement a tiered approach to data governance, appoint a dedicated data governance coordinator, and promote structured decision-making and active oversight of the Department’s data assets; and 3) Undertake a new inventory of roadway attributes using mobile LiDAR technology to replace the data inventoried 30 years ago, and develop enterprise-wide plans to capitalize on additional opportunities for MLS point cloud data.
