| 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 |
