TUTORIAL DETAILST01: V2X Communications: Overview, Technical Challenges, and Applications in Safety and Automated Driving Tutorial Code: 35uhj Proposer
Scope and Goals In this tutorial we cover the most important aspects of V2X (vehicle to everything) communications and its applications to safety and automated driving. This technology is in the early stages of deployment in North America, Europe, and other regions. The US DOT plans to require Dedicated Short Range Communications (DSRC) in new vehicles in the coming years. DSRC is used to communicate vehicle-to-vehicle (V2V) and vehicle-to/from-infrastructure (V2I), enabling a set of compelling safety, mobility, automated driving, and environmental applications. This tutorial focuses on the safety and automated driving use cases. We explain the DSRC protocol stack, collision avoidance applications, and technical challenges for deployment. We also present basics and underlying principles of new LTE-V technology. We discuss large-scale field tests and early deployment projects in the US, Europe, and Japan, e.g. the US Safety Pilot and the Rotterdam-Vienna Corridor Project. After presenting V2X basics, we provide detail analysis on a specific research problem that is of great interest: Channel Congestion. We discuss the merits of various approaches to address congestion, including avoidance and active control, as well as control modalities (message rate, transmit power, etc.). We end the tutorial with a discussion of the role V2X can play in support of automated vehicles, including a framework for cooperative mapping and perception. The primary goal of the tutorial is to empower the attendee to participate in this important emerging technology, whether as a researcher, a developer, or a planner. |
