According to the Minnesota DOT, Preparing Roads for Connected and Autonomous Vehicles, the infrastructure considerations for CAV include the following:
Pavement Markings – width and material. Signing - standardized, easily visible, and not blocked, damaged or faded. Traffic Signals - Create space at signal control cabinets for additional hardware related to CAV technologies. Consistency and Standardization - Install and maintain striping, signing and signals consistent with CAV algorithms and technologies. Pavement Maintenance. Data Capture and Information Sharing - Begin or continue collecting and organizing data for bridge heights, speed limits, load restrictions, crosswalks, roadway curvatures and other infrastructure characteristics. Communication Infrastructure. - In new construction and information technology infrastructure built for agency use, ensure adequate conduits for power and fiber optic cables. High-Resolution Mapping - Consider developing high-resolution mapping capabilities (MnDOT 2019).
