Because of the growing interest in LTE-V2X, there is a need to describe its
performance under various conditions and scenarios. This article explores the
deployment of long-term evolution vehicle-to-everything (LTE-V2X) technology for
vehicle-to-infrastructure (V2I) communication and delves into the deployment of
LTE-V2X communication in three major global regions: the United States, Europe,
and China. We begin with an overview of the functionality of LTE-V2X and
highlight the objectives of V2I communication in terms of safety and mobility
applications—and describe why it will be the predominant type of V2X in the
first few years of deployment. We also examine the specific Day-1 V2I message
sets standardized in each region, along with their potential applications and
benefits. The technical details and use cases using these messages are
discussed, along with the benefits they offer in improving the accuracy,
reliability, and safety for surface transportation. Additionally, our field
trial and simulation results demonstrate why, from a technical basis, LTEV2X is
the technology of choice in North America and China. In particular, the
performance of V2I and vehicle-to-vehicle (V2V) communication in a single 20 MHz
channel (Channel 183) is highlighted. The results show that LTE-V2X technology
can support both V2V and V2I communication and that Day-1 V2I messages can be
effectively transmitted and received in a congested urban environment. Overall,
we highlight the potential of LTE-V2X technology for V2V and V2I communication
in enabling safety and efficiency in the current and next generation of
transportation systems.
