Every year the U.S. Department of Transportation (USDOT) releases its ITS Benefits, Costs, and Lessons Learned update. Not surprisingly, one of the new topics covered is Connected Vehicles (CV) which aim to tackle some of the biggest issues facing the transportation industry- safety, mobility, and environmental impact.
Safety is a driving force for CV deployment sites. CV applications can provide a driver with 360° awareness giving them time to react to hazards they might not otherwise see. These applications would not exist without vehicles communicating with both each other and infrastructure; otherwise known as Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. This communication, which is currently being collected and disseminated with Dedicated Short-Range Communication (DSRC), is proving to make our roads safer than ever before; enabling applications like red-light violation warnings, reduced speed/work zone warnings, and spot weather warnings. These apps are estimated to reduce the severity of crashes by up to 80% at intersections or while changing lanes.
V2V Safety Applications
V2I Safety Applications
The Dynamic Mobility Applications program is an initiative led by the Intelligent Transportation Systems Joint Program Office (ITS JPO) within the USDOT. The program’s goal is to assist in developing, testing, and bringing mobility applications to all travelers, no matter the mode of transportation. While the goal may be simple by nature, the outcomes are impressive.
Multimodal Intelligent Traffic Signal System (MMITSS)
Intelligent Network Flow Optimization (INFLO)
Applications developed through the Applications for the Environment: Real-time Information Synthesis (AERIS) program envision a transportation system in which everyone will have access to the information needed to make better decisions, no matter the mode of transport. AERIS officially kicked off in 2009 with “Cleaner Air through Smarter Transportation” which encourages the development of technologies and applications that support reductions in fuel use and emissions. Whether it be freight or passenger vehicles that vision is quickly becoming a reality.

A major goal of the USDOT is to improve safety, mobility, and reduce environmental impact when it comes to our roads. CV technologies are improving each of these aspects and they are doing it now. Don’t let your city fall behind the curve. To learn more about these rapidly evolving technologies take a look at our on-demand webinars, Intro to Connected and Autonomous Vehicles and Traffic Controllers in a CV Environment.
