Determining the Impact of Connected and Automated Vehicle Technology on State DOT Maintenance Programs

Connected and Automated Vehicle (CAV) technology is progressing rapidly. Numerous research and deployment initiatives are underway as the transportation industry continues to examine how roadway assets such as traffic control signs, markings, signals, guardrail, computing systems, communications infrastructure and systems, and other permanent and temporary ancillary devices can be designed or enhanced to facilitate CAV operations. With the diffusion of CAV technologies, effects on state transportation agency maintenance programs—which have constrained budgets and workforces—need to be examined to ensure that transportation agencies are prepared for the challenges of CAV implementation while maintaining the existing roadway system and its ancillary roadway assets at an acceptable level of service. Research is needed to (1) explore the effect of CAV technologies on roadway and Transportation Systems Management and Operations (TSMO) asset maintenance programs, and (2) develop guidance on measureable standards and resource implications. The objectives of this research are to (1) estimate the current and future effect of dynamic CAV technologies on roadway and TSMO asset maintenance programs; (2) develop guidance on existing and proposed measureable standards associated with roadway and TSMO asset maintenance for preventive, reactive, and emerging maintenance needs; and (3) identify the associated resource and workforce development needs.
