通过将先进的无线通信、车载计算机处理、先进的车辆传感器、全球定位系统(GPS)导航、智能基础设施等尖端技术相结合，解决安全、移动性和环境挑战，互联汽车有可能改变我们所知的出行。在过去的五年里，应用原型和评估一直是联邦互联汽车研发活动的重点，产生了30多个互联汽车应用概念。这项工作还包括对四个美国交通部(USDOT)连接的车辆到基础设施(V2I)研究项目(V2I安全、动态移动应用(DMA)、环境应用程序：实时信息合成(Aeris)和道路天气管理)的安全、机动性和环境影响进行评估。考虑到这些评估活动到目前为止的结果，V2I联网车辆应用显然有可能对安全性、机动性和环境产生重大影响：(1)V2I联网车辆应用组合在信号网络中是有效的，特别是在确定信号配时的优先顺序和减少总延误(高达27%)、二氧化碳排放和燃料消耗(高达11%)方面。以路口为重点的安全应用程序每年可能解决多达575,000起撞车事故和5,100起死亡事件。(2)V2I联网车辆应用为拥堵的高速公路路段的流量管理增加了潜在的新功能，特别是在缓解瓶颈位置之前潜在的不安全速差、降低燃油消耗(高达4.5%)或减少重大事故造成的延误(高达14%)方面。曲线速度警告安全应用程序每年可能处理多达169,000起撞车事故和5,000起致命车祸。(3)许多应用的收益大小高度取决于路边、车辆或移动设备中的技术部署水平。然而，针对车队车辆的应用程序可能是早期的赢家-以及用于区分优先顺序或促进设施访问的应用程序。
Connected vehicles have the potential to transform travel as we know it by combining leading edge technologies— advanced wireless communications, on-board computer processing, advanced vehicle-sensors, Global Positioning System (GPS) navigation, smart infrastructure, and others—to address safety, mobility, and environmental challenges. Over the last five years, application prototyping and assessment has been a focus of federal connected vehicle research and development activity, resulting in more than three dozen connected vehicle application concepts. This effort also included assessments to measure safety, mobility and environmental impacts from four U.S. Department of Transportation (USDOT) connected vehicle Vehicle-to-Infrastructure (V2I) research programs (V2I Safety, Dynamic Mobility Applications (DMA), Applications for the Environment: Real-Time Information Synthesis (AERIS), and Road-Weather Management). Considering results to date from these assessment activities, there is a clear demonstrated potential for significant safety, mobility and environmental impacts from V2I connected vehicle applications: (1) Combinations of V2I connected vehicle applications are effective in signalized networks, particularly in prioritizing signal timing and reducing overall delay (up to 27%), carbon dioxide emissions and fuel consumption (up to 11%). Intersection-focused safety applications may potentially address up to 575,000 crashes and 5,100 fatalities per year. (2) V2I connected vehicle applications add a potentially new capability to flow management in congested freeway segments, particularly in the mitigation of potentially unsafe speed differentials in advance of bottleneck locations, reducing fuel consumption (up to 4.5%), or in the reduction of delay generated by major incidents (up to 14%). A curve speed warning safety application may potentially address up to 169,000 crashes and 5,000 fatal crashes per year. (3) The magnitude of benefits of many applications are highly dependent on the level of technology deployment at the roadside, in vehicles, or within mobile devices. However, applications targeting fleet vehicles may be early winners – as well as applications that serve to prioritize or facilitate facility access.
