• Abstract:
  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 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: ; • Combinations of V2I connected vehicle applications are effective in signalized networks, particularly in ; prioritizing signal timing and reducing overall delay (up to 27%), CO2 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. ; • 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. ; • 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
