Abstract:The connected vehicle research initiative is the core of the U.S. Department of Transportation’s intelligent
transportation system research program. The initiative is beginning to gain momentum in the research
community because of the development of a promising wireless communications technology—dedicated
short-range communications. Connected vehicle technology has the potential to transform the transportation
industry and significantly improve the quality of life of drivers. This study aims to explore the potential uses
of connected vehicle technology in real-world settings.
Researchers first conducted a comprehensive review of the state-of-the-art connected-vehicle research and
technologies. Once researchers had a thorough understanding of the technology, they focused on selecting
and developing the near-term practical applications that use connected vehicle technology. The research team
then sought expert opinions from the Texas Transportation Institute working group during two brainstorming
sessions, which produced two lists of potential applications and prioritized the applications based on
deployment feasibility. In particular, a total of five applications were selected for development of the full
concept of operations, including two in safety, two in mobility, and one in environmental security. These
applications address various problems, including wrong-way driving and unprotected-grade-crossing crashes
(safety); work-zone merge efficiency and safety, and freeway speed harmonization (mobility); and slipperypavement-
related crashes (environmental security).
