Impacts of Connected Vehicles and Automated Vehicles on State and Local Transportation Agencies--Task-Order Support. Infrastructure Modifications to Improve the Operational Conditions of Automated Vehicles

Connected and automated vehicle (CAV) technologies are quickly creating a growing need for roadways and other infrastructure to consider the impacts of CAVs as well as deployments limited to operational domains (OD). The OD is the area that represents conditional automation where the vehicle can safely operate and handle all driving functions. Limitations in OD may stem from factors that challenge an automated vehicle’s (AV’s) ability to accurately perceive the surrounding environment and effectively make decisions, such as in adverse weather or with degraded lane markings. While state and local agencies and other infrastructure owner-operators (IOO) may not be able to control some OD limitations, they can take steps to modify infrastructure to improve the OD, such as fostering accessibility and economic opportunities, connecting strategic locations, and attracting CAV testing and deployment. Infrastructure modifications may include infrastructure-to-vehicle (I2V) communication systems, signage, and other infrastructure components such as curbs and barriers to provide different levels of segregation between CAVs and other road users. To facilitate a smoother transition to CAV transportation, there is a need to provide guidance to aid IOO with the assessment of the impact of CAV deployment on roadway design, operations, and maintenance as well as the broader impact on procurement, regulatory requirements, and workforce needs and changes. The objective of this research is to provide guidelines for IOO on how to (1) align infrastructure modifications with technology that influences OD to best achieve the transition to CAV deployment, (2) identify and assess potential impacts of CAV deployment on roadway design, operation, and maintenance as well as the impact on procurement, regulatory, and workforce requirements, and (3) identify physical and digital infrastructure modifications that could improve the OD of CAVs.
