Rumble Strips: A Lifesaving Investment on Rural Maine Roads
The Close Call That Sparked a Safety Revolution
On a gray morning in June 2019, newlyweds Steven Lavrenz and Sandhya Madan from Michigan were wrapping up their honeymoon with a scenic drive from Acadia National Park to Boston Logan International Airport. Little did they know that their trip would almost take a tragic turn, highlighting a crucial issue in road safety.
As Lavrenz navigated Route 102, he witnessed a red pickup truck veering dangerously into his lane. Thanks to his quick reflexes, he swerved just in time, narrowly avoiding a collision. While he managed to escape unscathed, the truck crashed into the rear of his rental Subaru, totaling the vehicle.
The Grim Reality of Lane-Departure Crashes
This incident is not merely anecdotal; it reflects a broader trend on Maine’s roads. From 2010 to 2022, lane-departure crashes accounted for 30% of all traffic collisions in the state but were responsible for a staggering 73% of fatalities. This alarming statistic is further exacerbated by Maine’s treacherous weather, an aging population, and winding two-lane roads, which collectively contribute to the highest crash fatality rate in New England.
A Personal Awakening for a Safety Researcher
Lavrenz, a transportation safety researcher at Wayne State University, was no stranger to the risks associated with lane-departure crashes; this was the first time he had faced such dire consequences personally. A firm believer in the effectiveness of rumble strips, Lavrenz recalled his past work with the Federal Highway Administration to advocate for their installation on rural roads.
Yet, as he assessed the aftermath of the crash, he realized that Route 102 lacked the very safety feature that could have prevented the near-disaster. Inspired, Lavrenz took to social media to urge the Maine Department of Transportation (MaineDOT) to consider the installation of centerline rumble strips.
The Case for Rumble Strips
Recent research from the University of Maine provides compelling evidence for the effectiveness of centerline rumble strips. A comprehensive before-and-after analysis showed that their installation decreased head-on and sideswipe collisions by 28% to 48%. The study further revealed that the benefits of implementing rumble strips are estimated to be 14 times the installation costs.
“Rumble strips are one of our most cost-effective safety measures,” said Bob Skehan, director of MaineDOT’s Office of Safety and Mobility.
The Research Behind the Benefits
Conducted by Jhan Kevin Gil-Marin, a civil engineering student, this study utilized data from MaineDOT, comparing crash rates on roads with and without rumble strips. Unlike previous analyses, it focused specifically on crashes where rumble strips had been installed and then assessed their effectiveness in real-life scenarios.
Installed at a cost of approximately $3,500 per mile, the rumble strips quickly demonstrate a positive return on investment. Even with a conservative lifespan of seven years, they prove to be financially beneficial while significantly enhancing safety.
The Historical Context of Rumble Strips in Maine
When Per Gårder arrived in Maine in 1992, rumble strips were non-existent. His early conversations with fellow engineers revealed a shared commitment to enhancing road safety, motivated by both professional and personal experiences with traffic incidents. As MaineDOT began installing rumble strips on interstates in the mid-90s, Gårder’s research laid the groundwork for future initiatives.
In fact, studies have shown that the use of shoulder rumble strips alone has reduced sleep-induced crashes by 58%.
Overcoming Challenges and Misconceptions
Despite the clear safety benefits, the initial introduction of rumble strips in rural areas did raise noise concerns among locals. However, MaineDOT has adopted sinusoidal rumble strips, or “mumble strips,” which minimize noise while still serving their purpose of enhancing driver awareness.
Looking Ahead: The Future of Rumble Strips in Maine
While rumble strips currently line all interstate highways, much work remains to be done on rural roads, particularly in northern Maine. MaineDOT aims to implement about 100 miles of new rumble strips annually, primarily focusing on high-traffic areas. With approximately $750,000 allocated for these safety projects, funding primarily comes from the federal Highway Safety Improvement Program.
Despite this progress, some roads, like Route 102, remain unmarked. Lavrenz’s experience serves as a reminder that proactive safety measures can save lives long before tragedies occur.
A Call to Action
“Human drivers will always make mistakes,” Lavrenz emphasizes, advocating for widespread implementation of rumble strips as a simple yet effective measure to enhance road safety. The data clearly supports this view: rumble strips could be the lifesaver that countless drivers need on Maine’s perilous rural roads.
