Pavement Marking

In a report developed by the U.S. Government Accountability Office (GAO), it was recommended that the U.S. Department of Transportation (USDOT) establish plans to “better manage” initiatives and efforts related to Connected Automated Vehicles (CAVs). GAO officials state within the report, which was released in November 2017, that their reasoning behind the research efforts are based on the potential promise of CAVs to provide transformative safety and mobility benefits, but these benefits also will come with a set of safety and infrastructure challenges for policymakers.

While it also was noted that other components such as urban versus rural settings and local ownership of roadways will play a hand in infrastructure adaptations, many experts in automation and infrastructure back up the report’s claims, and assert that consistent and proper maintenance of the current roadway system is of the upmost importance for conventional and AV motorists — especially when it comes to pavement markings.

ATSSA has a dedicated group of members on its Pavement Marking Committee (member login required), who are working to assert the proper maintenance of pavement marking and advance technologies being developed to help increase safety benefits and accommodation of CAVs. The committee has developed a list of policies and continues to work toward advancing the collaboration between the roadway safety industry and automakers as America progresses toward an automated future.

Minnesota and South Carolina women’s lives saved by guardrails

Each day guardrails save lives on our nation’s roadways. They are part of an important integrated safety system that helps to mitigate roadway departure (RwD) crashes.

WilsonThey give people second chances, people like Melissa Klohn, and Terecia Wilson and her family. Klohn, from Shakopee, Minnesota, was saved by a median cable in April 17, 2007. Wilson, from Richland County, South Carolina, was saved, along with her family, by a median cable on Nov. 8, 2008.

Klohn, a mother of three, was driving on I-94 near the Elk River and Rogers Exit. Traveling in the left lane, she approached a section of roadway where three lanes merge into two, and where other vehicles are simultaneously entering the highway.

As the lanes converged, a bus traveling in the center lane failed to see Klohn’s vehicle and moved into the left lane. With nowhere to go, Klohn hit the bus. She lost control of her car and her vehicle was projected into the highway median. Klohn hit the cable barrier straight on and it caught her vehicle. Her car spun around and scraped along the length of the barrier for a distance, but when her vehicle finally came to a stop, the median cable held it securely in place. Klohn left the scene of the accident uninjured.

Klohn“I thought it was all over. I thought I would die. Without the median cable barrier, I would have crossed the freeway. There was not a lot of room in the median. I was surprised I didn’t bounce back into the lanes. The cable kept me right in the median,” Klohn said.

In Wilson’s case, her family was returning from a night out at the movies in Columbia, South Carolina, on a Saturday evening. Traveling westbound on I-26 in the left lane, there was heavy traffic all around them.

Suddenly, a fast-moving SUV traveling eastbound veered out of its lane and headed straight toward them. With the heavy traffic surrounding their vehicle, they had nowhere to go to escape a head-on collision. The SUV glanced off the median cable and came back onto the interstate. The cable barrier prevented the SUV from crossing over the median and into the oncoming lanes of traffic, thus preventing a major accident. Wilson and her family arrived home safely.

“Thank goodness for the cable guardrail. We don’t know if the SUV driver had fallen asleep or was not paying attention. Had the cable guardrail not been there, the SUV would have hit our vehicle and caused a multivehicle collision, based on the traffic surrounding us. We were very thankful to reach our destination,” Wilson said.

Klohn and Wilson’s accounts are just two examples of how guardrails save lives each day. For more information and to read more stories like Klohn and Wilson’s, visit
