Functional architecture of network-based driving assistance for autonomous vehicles

Abstract

Recommendation ITU-T Y.4471 defines a reference functional architecture of network-based driving
assistance (NDA) for autonomous vehicles. It clarifies the concept of NDA, specifies key functional
entities and defines reference points between entities. The use cases and operational procedures are
also provided in Appendices I and II, respectively.
To improve the driving of autonomous vehicles, coordination between vehicles and infrastructures
needs to be improved with network technologies to provide the increasing transportation services and
application requirements. NDA can improve the safety and efficiency of automated driving with
capabilities of cooperative perception and decisions. Copyright © ITU 2008 All Rights Reserved
