“In 2020, … an average of 104 people died each day on our roadways,” said Rob Molloy, Ph.D, director, National Transportation Safety Board (NTSB) Office of Highway Safety. “For several decades, the number of fatalities has been dropping. But we've seen this trend change in the wrong direction.”

Molloy presented these findings during his keynote address at the virtual Fleet Safety Conference on Sept. 21. In the presentation, he detailed how NTSB chooses to launch investigations, the layers of crash causes, and the board’s recommendations to help make transportation safer for the traveling public.

With just 30 people to investigate crashes, the NTSB has established a ranking system to help identify highway crashes in which it chooses to launch investigations. The criteria are based on four basic questions:

  • Is there a high public interest, and is the board able to help restore public confidence?
  • Are there potentially new safety issues that have not been addressed?
  • Can the NTSB make a difference or bring a unique perspective that’s important to the discussion?
  • Does NTSB have the resources?

“When we hear what is causing most of the crashes on our highways, it’s easy to say 94% are caused by human error,” Molloy said. “Unfortunately, this myth can get in the way of finding solutions. If humans cause all the crashes, why do we need to improve vehicles or highways? Why don’t we just get rid of humans as drivers? We’ll make little progress on highway safety until we move past this myth.”

There are many layers of causalities in a crash, and each layer has flaws that can align with one another leading to a crash, according to Molloy. The layers NTSB examines are human, vehicle, operational, highway, and survival factors.

The Investigators

Human performance investigators look at human elements that may influence error, such as work environment, equipment design, cell phone use, or alcohol or drug impairment. Vehicle factor investigators conduct detailed examination of mechanical issues and other aspects of vehicles involved in the crash to determine whether the adequacy or failure of components caused the crash. Motor carrier investigators focus on operations of the motor carrier, and routine elements of driver qualifications, drug testing, hours of service and maintenance are reviewed.

Highway factors investigators examine and document the crash scene, looking into environmental position, such as weather and physical evidence at the scene. They also examine highway elements, such as traffic signs, markings, barriers, signals and traffic characteristics of the road and environment. The survival factors group conducts an on-site detailed documentation of what may have contributed to injuries and fatalities, interviews vehicle occupants and witnesses and examines the emergency response.

Party members from law enforcement, highway safety organizations, and other federal agencies assist investigators by providing technical expertise. Investigators and party members form groups that work together to build an actual account of the crash that the investigator can use to develop an analysis of the crash.

“These groups help us understand why the accident occurred, and more importantly, what we can do to keep it from happening in the future,” Molloy said.

During the pandemic, people’s use and addiction to cell phones have increased, and based on research NTSB conducted regarding how automation affects performance, the more that people trust automation, the more likely they were to rely on it. Additional research has clearly shown that companies benefit when they have a cell phone policy in place to prevent distracted driving.

NTSB’s Most Wanted

In 1990, the NTSB first created its most-wanted list for safety improvements to help make transportation safer for the traveling public. The revised list includes these five areas of recommendations:

  • Prevent alcohol- and drug-impaired driving. Actions: improved drug testing, first-offender interlock laws, a blood alcohol content limit of .05, allowing hair testing and best practices for all fluid testing.
  • Eliminate distracted driving. Actions: state laws banning cell phone use while driving, company distraction policies and cell phone manufacturer lockouts.
  • Collision avoidance in connected vehicle technology. Actions: ensure each vehicle has connected vehicle technology, improving forward collision testing, ratings for collision systems, and adding forward collision warning systems as standard equipment on all vehicles.
  • Form a comprehensive strategy to eliminate speeding crashes. Actions: speed-limiting technology for all vehicles, better speed detection, automated speed enforcement and better speed limit enforcement.
  • Protect vulnerable users through a safe systems approach. Actions: design safe roads and vehicles and reduce speeds to mitigate injuries.

2020 Statistics: Motor Vehicle Fatalities

The National Safety Council estimates that in 2020:

  • 42,060 people died in crashes, an 8% increase over 2019 and the largest number of motor vehicle deaths in 13 years.  
  • Yet vehicle miles traveled fell 13% compared to 2019.  
  • The mileage death rate was 1.49 deaths per 100 million miles traveled, up 24% from 1.20 in 2019.

“Conventional approach to road safety in the U.S. is not driving down fatalities and injuries,” Molloy said. “We need a paradigm shift. Reaching zero will require a transition to a holistic safe-systems approach. The principles underpinning a safe system acknowledges that humans make mistakes that lead to crashes. But no one should lose their life or become seriously injured as a result of the crash. Road safety must be a shared responsibility, and all parts of the system must be strengthened so that if one part fails, road users are still protected.”
