Taxonomy and Definitions for Terms Related to Cooperative Driving Automation for On-Road Motor Vehicles
This document describes machine-to-machine (M2M) communication to enable cooperation between a subject vehicle and other participants. The cooperation supports or enables performance of the Dynamic Driving Task (DDT) for a subject vehicle with driving automation feature(s) engaged. Other participants may include other vehicles with driving automation feature(s) engaged, shared road users (e.g., manually operated vehicles or personal devices) or infrastructure owners and operators (e.g., traffic signals, work zones).
Cooperative driving automation (CDA) aims to improve the flow of traffic and/or facilitate road operations by coordinating the movement of multiple vehicles in proximity to one another. This is accomplished by, for example, sharing information that can be used to influence (directly or indirectly) the dynamic driving task. Cooperation among multiple participants and perspectives in traffic can improve safety, mobility, situational awareness and operations.
Cooperative strategies may be enabled by the sharing of information in a way that meets the needs of a given application. The needs may be expressed in terms of performance characteristics, such as latency, transmission mode (e.g., one-way, two-way), range, privacy, and information content and quality. There are several potential technologies for communicating information between the subject vehicle and other participants.
