J3282_202406 Cooperative Infrastructure CDA Feature: Cooperative Permissive Left Turn Across Opposing Traffic with Infrastructure Guidance

Cooperative driving automation (CDA) applications are expected to be enabled by the increasing penetration of Cooperative Automated Driving System (C-ADS) equipped vehicles, particularly fleet-operated ADS-dedicated vehicles (ADS-DVs) in urban areas (both ride-hailing and delivery fleets). These C-ADS-equipped vehicles (i.e., with SAE Levels 3 to 5 driving automation) may operate on signalized arterial roadways. Infrastructure Owners/Operators (IOOs) are also being encouraged through federal policy to equip signalized intersections with technology to provide information that could be used to support CDA applications. These applications can operate with greater safety and efficiency with a cooperative intersection infrastructure. This report provides a concept of operations needed to evaluate a CDA Feature for a permissive turn across opposing traffic.
