On Tuesday, the U.S. Department of Transportation (DOT) announced a proposed rule, requiring the inclusion of车辆到车辆(V2V) communication technology in new cars. This不tice of Proposed Rulemakingwould enable a “multitude of new crash-avoidance systems that, once fully deployed, could prevent hundreds of thousands of crashes every year,” according to a statement.
V2V技术利用专用的短程通信（DSRC）将位置，方向，速度和制动状态传输到附近的车辆，使它们基本上彼此“谈话”。在新车中，该技术在约300米的范围内运营，将以标准化的格式更新和传输每秒10次的数据，使其他车辆能够识别风险并提供具有潜在崩溃警告的驱动因素。
“我们据我们愿意实现拯救生命的运输技术的潜力，我们携带球，”美国运输秘书Anthony Foxx表示。“这一长期承诺的V2V规则是该进展的下一步。一旦部署，V2V将在道路上提供360度的情境意识，并将帮助我们提高车辆安全性。“
The DOT’s National Highway Traffic Safety Administration (NHTSA) estimates that the V2V technology could reduce the severity of up to 80 percent of “non-impaired” crashes. The rule would also integrate extensive privacy and security controls, preventing the technology, which operates on a 75 MHz band of the 5.9 GHz spectrum, from linking any information to individuals. The current proposed design employs a 128-bit encryption, compliant with the National Institute of Standards and Technology (NIST).
Also on the docket is the NHTSA’s plan to issue guidance for vehicle-to-infrastructure (V2I) communications, which would allow vehicles to “talk” to traffic lights, stop signs, and other roadway infrastructure, reducing congestion and improving safety.
The NPRM, which represents the first proposed mandate of V2V technology in the world, will be open for public comment for 90 days. After that, the proposal will be reviewed and possibly amended before a final ruling is issued.
