Automated Driving Systems (ADS) Operational Behavior and Traffic Regulations Information – Proof-of-Concept Demonstration Report

Foreword

Automated driving systems (ADS) and cooperative ADS will transform how vehicles interact with each other; other travelers; and transportation infrastructure, communications infrastructure, information systems, and system management and operations strategies. Infrastructure owner- operators (IOOs) have been grappling with questions about how ADS will interact with the transportation system—and what IOOs can do to prepare. Uncertainty about the timing of ADS technology development has made this preparation a challenge. The Federal Highway Administration has been exploring automated vehicles (AVs) to understand national automation readiness and to help facilitate AV integration into the transportation system. This exploration includes assessing data and information needs for AVs and identifying practice-ready information and tools to guide AV integration.

A key aspect of development of ADS behavior and safe integration of AVs into the transportation system is access to data about traffic laws and regulations. This report details the challenges of establishing an ADS-ready traffic laws and regulations database, and accessing and exchanging requirements to support the sharing and consumption of the information within the ADS ecosystem. It also identifies the basic requirements for collaboration among State and local traffic code stakeholders, as well as ADS behavior subject matter experts.

This report will be of interest to CDA system developers, analysts, researchers, and application developers.
