Connected and Autonomous Vehicle (CAV) technology heavily depends on “reading the road.” Research initiatives are underway as to how roadway assets such as traffic control signs, markings, signals, guardrail, computing and communications systems, and ancillary devices can facilitate CAV operations. As the presence and condition of roadway features is vital to the safe and reliable functioning of CAVs, state and local transportation agencies, with constrained budgets and workforces, must strategically plan and prepare now for the potentially increased maintenance needs demanded by CAV. Of specific interest is the result from the NCHRP 14-42 project survey of transportation agencies and OEMs on these issues.
