摘要：	Connected Vehicle Infrastructure (CVI), a component of the broader category of Intelligent Transportation Systems (ITS), focuses on communications and connectivity between vehicles and infrastructure. This report provides an overview of CVI technology, reviews existing and proposed legislation relevant to CVI implementation, identifies existing funding mechanisms, reviews CVI pilot programs, and presents potential implementation barriers. CVI technology uses Vehicle to Infrastructure (V2I) technology and Infrastructure to Vehicle (I2V) technology to allow units in vehicles, or on-board units (OBU), to communicate with units built into transportation infrastructure and vice-versa. Other types of connected vehicle technology allow vehicles to communicate with other vehicles, data networks, or pedestrians, all using the same OBU that is needed for V2I communication. CVI related legislation, funding, and deployments have primarily come from the federal level. Many states have passed automated or connected vehicle legislation, but none directly address CVI. Given the variety of uses of this technology, funding can be acquired through several federal-aid programs. Federal-aid programs which include ITS funding typically provide 80 to 90 percent of eligible project costs if certain criteria are met. While the benefits that can be derived from these technologies can be substantial, the high initial costs of deployment can be a barrier. As such, the need for funding opportunities for state and local governments is crucial. The emerging nature of CV technology has resulted in the creation of numerous test sites and pilot programs across the country. Some are federally funded, but most are affiliations of state and local governments and private interests. The National Highway Traffic Safety Administration (NHTSA) has proposed a requirement that dedicated short range communication (DSRC) devices be installed in new passenger vehicles by 2023, which would allow most personal vehicles to take advantage of CVI technology and create the fleet market penetration that would strengthen the value proposition for public investment. Many barriers to CVI technology implementation exist. Absent a federal mandate, it seems unlikely that DSRC-based CVI will be prevalent in the future. There is also uncertainty over continued allocation of the 5.9GHz band for DSRC uses, as the Federal Communications Commission is considering the possibility of sharing this spectrum with Wi-Fi devices. There are also questions about whether 5G cellular network technology could render DSRC technology obsolete.
