We’re on the cusp of a potentially huge breakthrough in transportation safety, mobility and environmental sustainability. Vehicle crashes cause more than 32,000 deaths each year and are the leading cause of death for Americans between the ages of 4 and 35 years, according to the Centers for Disease Control. Connected vehicle technology could be a game-changer for safe transportation.
Connected Vehicle technology uses dedicated, short-range wireless communications (DSRC) combined with advanced vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) safety applications to reduce crashes. This allows vehicles to communicate with each other and with the infrastructure - traffic signals, work zone equipment or pavement sensors, for example. Connected vehicles send and receive messages to and from other vehicles and to roadside equipment ten times per second. That’s more than a human can absorb, so the technology gives the car premonition, where it can sense things that the driver cannot.
National Highway Traffic Safety Administration (NHTSA) research found that connected vehicle systems have the potential to address more than 80% of unimpaired driver crash scenarios. However, more research is needed to understand the true effectiveness of this technology, so the USDOT's ITS Program launched the Safety Pilot Model Deployment on August 21, 2012 in Ann Arbor, Michigan. This large-scale deployment of connected vehicle technology involves real-world, all-weather driving conditions, real drivers recruited from the community, and more than 2,800 vehicles equipped with the technology. The goal is to create a highly concentrated connected vehicle communications environment with vehicles “talking to each other” and to roadside equipment.
