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 slippery-pavement-related crashes (environmental security).
