Roadway Digital Infrastructure (RDI) is a term that has been increasingly used in the context of roadway operations to describe the non-physical aspects that supplement the physical infrastructure in the support of operations. The collection, movement, and use of data is the most widespread example of digital infrastructure. This project describes collaborative and coordinated national-level RDI activities being conducted. In addition to researching and documenting national RDI activities, this ENTERPRISE project conducted engagement and discussions among members around conceptual or actual examples of RDI deployments in their agencies. Key takeaway and themes from these discussion include: transportation agency procurement of RDI systems and support is still evolving, transportation agency integration of RDI into existing systems is challenging, the Department of Transportation (DOT) role in RDI is still evolving with unanswered questions, there is some confusion about the term RDI and the justification for investments in it, and RDI data presents new opportunities and challenges for DOTs.
