Determining State DOT Maintenance Program Implications of Connected and Automated Vehicles

Connected and Automated Vehicle (CAV) research and technology are progressing at a rapid rate. Research is underway to examine how traffic control signs, markings, signals, and other permanent and temporary ancillary devices (highway assets) can be designed, enhanced, or applied for vehicle navigational guidance. However, state maintenance engineers often cite inadequate resources to maintain the existing highway system and its ancillary highway assets at an acceptable level of service. Without knowing how the technology of CAV will affect the required level of service or responsiveness for the maintenance, repair or replacement of those highway assets, the use of these assets for CAV vehicle navigation could be impaired and the adoption of CAV hindered. Research is needed to explore the financial, workforce and level of service impacts demanded to maintain these highway assets for successful CAV navigation. The objective of this research is to examine the maintenance program implications of the use of highway assets for vehicle navigation for CAV. The research team should work in conjunction with research under way, CAV developers, and highway asset vendors to determine how the assets will be used to meet the needs of the human driver and the CAV driver. The research shall identify the current resources (e.g., financial, workforce) allocated to state DOT maintenance programs to maintain, repair, and replace highway assets and the associated levels of service (e.g., condition, response time, life cycle). It shall also identify proposed CAV navigational systems, particularly those that rely on highway assets, to determine responsiveness, redundancy, and level of services required for meeting the CAV navigational needs. The deliverables should include an assessment of the current state of maintenance programs as well as the required future state in order to support CAV needs. Recommendations will be provided to CAV developers, highway asset vendors, and state DOT officials to design a system that can efficiently and effectively be maintained.
