AAA:  The Potential For Advanced Driver Assistance System To Save Lives

The American Automobile Association is sharing new AAA Foundation for Traffic Safety research into Advanced Driver Assistance Systems (ADAS). 

ADAS Could Prevent 37 Million Crashes

The new AAA research estimates that ADAS technologies could prevent approximately 37 million crashes, 14 million injuries, and nearly 250,000 deaths over the next 30 years. This would represent 16% of crashes and injuries and 22% of deaths that would otherwise occur on U.S. roads without these technologies.

“The findings from this latest study on the AAA Foundation’s work in emerging technologies suggest that ADAS have the potential to transform road safety,” said Dr. David Yang, president and executive director of the AAA Foundation. “However, the full safety benefits of ADAS will not be realized unless they are fully understood by the consumer, used properly, and widely adopted.” 

Researchers say safety benefits of ADAS could be larger or smaller, depending on many factors, including the rates of consumer uptake, use, and the future development of these technologies. AAA also cautions that technology limitations still exist, and says while ADAS may save 250,000 lives over the next 30 years, nearly 900,000 lives will be lost on our roads if current trends continue. 

Common ADAS Features

Here are a few of the most common ADAS features: 

• Forward Collision Warning:  Detects a potential collision with a vehicle ahead and alerts the driver. Some systems also provide alerts for pedestrians or other objects.  
• Adaptive Cruise Control: Cruise control that also assists with acceleration and braking to maintain a driver-selected gap to the vehicle in front. Some systems can come to a stop and continue, while others cannot.  
• Automatic Emergency Braking:  Detects potential collisions with a vehicle ahead, provides forward collision warning, and automatically brakes to avoid a collision or lessen the severity of impact. Some systems also detect pedestrians or other objects.  
• Lane Departure Warning:  Monitors the vehicle’s position within the driving lane and alerts the driver as the vehicle approaches or crosses lane markers.  
• Lane Keeping Assistance:  Provides steering support to assist the driver in keeping the vehicle in the lane. The system reacts only when the vehicle approaches or crosses a lane line or road edge.  
• Blind Spot Monitoring:  Detects vehicles in the blind spot while driving and notifies the driver of their presence. Some systems provide an additional warning if the driver activates the turn signal. 

AAA notes that unlike full "automation", which isn't available commercially yet, ADAS works to form a vehicle’s “safety net.” The study found that the safety benefits of ADAS will vary depending on the type of system and how it is used.

Previous ADAS Studies

Last year, AAA engineers examined automatic emergency braking systems, which effectively prevent rear-end crashes but less so when encountering bicyclists or vehicles crossing paths. 

In other recent Foundation research, AAA found that drivers may initially lack the appropriate knowledge of Adaptive Cruise Control (ACC) to use it properly.  Read more in our previous post here.

Safe System Approach

AAA says the Foundation’s research reinforces the importance of the Safe System Approach (SSA). It’s a strategic way of leveraging the engineering and behavioral countermeasures proven effective at preventing traffic crashes and the injuries that can result from them. 

“The future for ADAS is bright, but it’s not a cure-all,” said Jake Nelson, AAA’s director of traffic safety advocacy. “While these technologies offer substantial safety benefits, we cannot engineer our way out of traffic injuries and deaths on U.S. roads. Investments in a diversity of proven traffic safety measures, including but not limited to vehicle technology, is in order.” 

AAA is urging automakers to adopt a standard naming convention for vehicle technology to ensure drivers understand the capabilities of catchy, marketing-driven branded names for popular systems.
