Ohio State Researchers Find Road Design Changes Can Reduce Distracted Driving Crashes

Columbus, Ohio (Nov. 19, 2018) – While efforts to combat distracted driving have primarily focused on passing new laws and changing driver behaviors, a new study from The Ohio State University’s Risk Institute reveals the important impact that modifying road design can have on reducing the frequency and severity of distracted driving crashes.

Researchers Zhenhua Chen and Youngbin Lym, assistant professor and his PhD student, in city and regional planning at The Ohio State University, found a 35 percent increase in distracted driver fatalities in Ohio and a 23 percent increase in serious injuries for the period 2003-2013. Additionally, distracted driving crashes were more severe in some road environments, such as work zones where they were up to two times more likely to be fatal.

This research found that urbanized areas such as Columbus, Cleveland and Cincinnati had much higher risk in vehicle crashes than other regions in Ohio. Even the length of a roadway segment or number of lanes had an impact on the frequency of distracted driving crashes. On the other hand, roundabouts had a significant effect on reducing the severity of distracted driving-related crashes. Other road environments that have a median or a shoulder with an asphalt pavement were also found to have fewer distracted driving crashes.

“This study helps to highlight that there is a need to improve traffic safety and road management,” said Phil Renaud, executive director of The Risk Institute at The Ohio State University Fisher College of Business. “It provides new evidence that supports taking steps to improve traffic signs and safety regulations for distracted driving in specific areas. There are things we can do on a local, city level to lower crash frequencies and severities.”

Key findings also include:

  • Distracted driving-related crashes account for approximately 18 percent of overall Ohio crash fatalities and 16 percent of Ohio serious injuries.
  • Distracted driving-related crashes are up to 49 percent more severe when they occur on a highway system.
  • The risk of vehicle crashes due to distracted driving is found to be highest in the Columbus area.
  • Distracted driving crashes are 5-10 times more likely to be fatal than severe in a rear end and or angle crash.
  • Roundabouts were found to be the single most effective road design in reducing the rate of crashes and crash severity. Overall, within the data (2013-2017) there were no fatal crashes within roundabouts.

The increase in distracted driving-related crashes in Ohio has become a major concern to various stakeholders, including insurance companies, transportation planners and policymakers. To help address this problem, which is so costly in terms of lives, medical bills, car repairs and insurance costs, the Property Casualty Insurers Association of America (PCI) funded The Risk Institute’s study and is working to raise awareness about the dangers of distracted driving.

“Those of us in the insurance industry hear far too many stories of how families are devastated because someone was texting behind the wheel,” said Bob Passmore, assistant vice president for PCI. “This research confirms some of the trends we have seen in auto insurance claims. Congested, urban roadways, infrastructure challenges along with the ubiquitous use of electronic devices combine to create hazardous driving conditions. As we have seen with other motor safety issues such as seatbelt use and drunk driving, there is no single answer to addressing the problem of distracted driving. It takes a coordinated strategy combining the enactment of laws, strong enforcement, drivers taking personal responsibility to avoid distractions and improvements in transportation infrastructure design.”

What researchers are doing to tackle distracted driving

February 22, 2018 marked one year since The Risk Institute embarked on a nationwide initiative to predict and curb distracted driving behaviors.

To celebrate our achievements over the last year and to reinvigorate our efforts, we hosted about 100 members of the initiative for an anniversary event. 10TV wrote a great piece about the work we’ve been doing.

We welcomed Fletcher Cleaves, a former collegiate athlete who is now paralyzed from the mid-chest down after a distracted driving crash several years ago; Maria’s Message, who is providing the awareness and reach for the initiative as we work together to create a research-based driver’s education curriculum; and students from Olentangy High School who we worked with to do some innovative research into driver habits and training.

Is our word choice causing more car wrecks?

It’s a car crash, not an accident. That’s the message coming from behavioral researchers partnered with The Risk Institute Distracted Driving Initiative at The Ohio State University Fisher College of Business, who recommend that people need to stop using the word “accident” when comes to distracted driving crashes, as well as several other behavioral recommendations.

“One of the keys to curbing distracted driving fatalities and crashes is to change behavior and attitudes towards driving while distracted,” said Stacey Emert, partner at InAlign Partners and lead of the initiative’s behavior team. “One of the most effective methods is called social norming. This is essentially the collective thought about a behavior. Over the last 50 years, we’ve successfully flipped the collective thought on smoking, drunk driving, and child safety seats. We need to flip the collective mindset on distracted driving. We do this in part by changing the language we use: distracted driving accidents become crashes. You wouldn’t call a plane crash a plane accident.”

The Distracted Driving Initiative at The Risk Institute at is a nationwide endeavor comprised of dozens of companies, government entities, and researchers seeking to combine key partnerships, critical research, and leading-edge technology to predict and curb distracted driving behaviors.

“Unfortunately, people make choices that harm their ability to drive, like driving drunk, and so many traffic deaths could’ve been prevented if people stayed off the roads when drunk,” says Brittany Shoots-Reinhard, a psychology researcher at The Ohio State University. “In the 1980s, people were resistant to laws against drinking and driving, but now, we don’t drive drunk or let our friends drive drunk, either.”

The number of fatal traffic accidents rose 7.2 percent nationally in 2015 according to the National Highway Traffic and Safety Administration. It is the greatest year-over-year increase since 1966. Distracted driving was a factor in about 10 percent of auto deaths; the exact percentage is difficult to determine due to privacy rules and other factors.

“We can change the norms about distracted driving, too. These crashes are entirely preventable; at Ohio State, we’re working together to figure out how to help people not drive distracted”,” said Shoots-Reinhard.

The Risk Institute at The Ohio State University Fisher College of Business brings together practitioners and researchers to engage in risk-centered conversations and to exchange ideas and strategies on integrated risk management. Through the collaboration of faculty, students and risk management professionals, The Risk Institute addresses risk at a broad cross section of industries and is dedicated to developing leading-edge approaches to risk management.

The Distracted Driving Initiative at the Risk Institute began in February 2017. Industry partners involved with the project are Honda Inc., Aon Benfield, Nationwide, NiSource, Ford, Motorists Insurance, DHL, State Auto, Freer Logic, TrueNorth, and others. Representing the legal and governmental branches are the Ohio Attorney General’s Office and the Ohio Department of Public Safety. Ohio-based Root Insurance, Smart Drive, Greenroad, and eDriving Fleet make up the technology voices in the conversation. A dozen researchers and thought leaders from OSU representing behavioral science, engineering, automotive research, risk and others make up the research arm of the initiative.

OSU research institute leads nationwide initiative to curb distracted driving

The Risk Institute at The Ohio State University Fisher College of Business is leading a nationwide initiative comprised of dozens of companies, government entities, and researchers seeking to combine leading-edge research with industry expertise in order to predict and curb distracted driving behaviors. The project officially kicked off on Wednesday, February 22 at a roundtable discussion at The Fisher College of Business. 

“Distracted driving is an epidemic across the country. Every day you hear ‘distracted driving is killing people,’ and it is, but nothing is being done to figure out how to stop it,” says Phil Renaud, Executive Director of the Risk Institute. “That’s why we started this initiative — to create actionable change.” 

The number of fatal traffic accidents rose 7.2 percent nationally in 2015 according to the National Highway Traffic and Safety Administration. It is the greatest year-over-year increase since 1966. Distracted driving was a factor in about 10 percent of auto deaths; the exact percentage is difficult to determine due to privacy rules and other factors.

“Nationwide Insurance has a long history of promoting safety for our members,” says Larry Thursby, Vice President of Personal Auto Product and Pricing at Nationwide Mutual Insurance Company.  “We recognize that distracted driving is an issue and we’re looking forward to working with a team of professionals from across the country to find solutions that protect families in every community.”

The consortium identified a three-tiered approach: research, legislation, and technology.

Michael LaRocco, president and CEO of State Auto Insurance Cos., says that collaboration is the reason partnerships between industry, research, and government are crucial to a project like this saying, “This isn’t a problem that will be solved by legislation, research or technology alone. That’s why we’re working directly with researchers to apply their research to everything from car design and manufacturing to insurance, and using new technology to our advantage.”

Practical research application is a crucial component of this initiative, particularly behavioral research. 

“Understanding what makes people do what they do is the first step to changing that behavior,” says Ellen Peters, Professor of Psychology at The Ohio State University. “At a dangerous curve in the UK, for example, they played with drivers’ peripheral vision.  As drivers approach the curve, they see trees planted next to the road at decreasing distances apart. This funnel of trees creates a visual illusion that tricks drivers into feeling as if they’re speeding. As a result, people slow down.”

Renaud highlighted the Risk Institute’s involvement in bringing this project and all the involved partners together saying, “We are uniquely positioned to facilitate valuable conversation between academics and practitioners. The Risk Institute is rooted in research, dedicated to education, and committed to collaboration. This initiative is the perfect amalgamation of those values, and we are so excited to get started.”
