摘要：	A connected-vehicles program has been undertaken by the U.S. Department of Transportation and its partners, with the goal of exploring and possibly enabling a new generation of technology to address highway transportation safety, mobility, and environmental challenges. This program has been underway for several years, and one area of intensive work has been the development of enabling devices, to be installed onboard vehicles, which use wireless technology to communicate with nearby vehicles and the infrastructure. This can be achieved through 5.9 GHz dedicated short-range communications (DSRC). Such technologies represent highly capable, low-cost alternatives or complements to vehicle-based crash avoidance systems. The wireless-enabled systems may enable vehicle-to-vehicle (V2V) applications as well as vehicle-infrastructure (V2I) applications, and would be capable of interfacing with other devices as well (V2X). This study sought to identify and prioritize issues unique to commercial vehicles that affect the interoperability of DSRC communications, and especially V2V safety applications. V2V safety applications represent a primary set of applications for DSRC because they leverage the unique aspects of DSRC: low latency, and design for broadcast mode (as opposed to peer-to-peer). A series of ground-breaking projects and activities have been underway, and are still ongoing. The results presented in this report identify and prioritize issues related to connected vehicle systems and applications that are unique to commercial vehicles. In particular, the technical aspects of the exchange of information were studied. This project considered the current state of the art, and identified areas in which commercial vehicle considerations may result in revisions to past decisions or changes to future plans. This focus was necessary to support upcoming activities to equip heavy trucks with these connected vehicle systems, and because the breadth of commercial vehicles was not possible to consider in the scope of this project.
