Centerline rumble strips are proving to be one of the most cost-effective methods for reducing head-on and opposite sideswipe collisions on rural roads. Recent studies conducted by civil engineers at the University of Maine demonstrate that these grooved lines can reduce such incidents by 28% to 48%, saving both lives and significant financial resources.
In the early 1990s, when Per Gårder arrived in Maine from Sweden, the concept of rumble strips was virtually unknown in the state. Inspired by personal experiences with road accidents, Gårder dedicated his research to studying shoulder rumble strips, a technology that originated in New Jersey during the 1950s. By analyzing police reports of fatal crashes on Maine's interstates between 1989 and 1993, Gårder discovered that nearly half involved drowsy drivers. The subsequent installation of hundreds of miles of continuous shoulder rumble strips along Maine’s interstates reduced sleep-induced "run-off-road" crashes by an impressive 58%.
Building on this success, MaineDOT began installing centerline rumble strips on state roads in 2006. These strips were specifically designed to address head-on collisions, which pose a significant risk due to the high speeds involved. Bob Skehan, director of MaineDOT’s Office of Safety and Mobility, explained that these collisions are equivalent to crashing into a fixed object at 100 miles per hour. The implementation of centerline rumble strips resulted in a dramatic reduction in head-on crashes, cutting them in half during the initial period and eliminating fatal collisions entirely.
Despite their proven effectiveness, the introduction of rumble strips faced resistance from some rural residents concerned about noise pollution. Bill Muir, a neighbor near Route 302 in Bridgton, described the sound as resembling a tractor-trailer shifting gears. In response to these complaints, MaineDOT transitioned to sinusoidal or "mumble" strips in 2018. These quieter alternatives significantly reduce external noise while maintaining the necessary vibration inside vehicles, effectively addressing community concerns.
This shift has been instrumental in gaining public acceptance. According to Skehan, the adoption of mumble strips has virtually eliminated noise-related complaints, allowing MaineDOT to continue expanding the use of rumble strips across the state. Today, all interstate highways in Maine feature edge rumble strips, although centerline grooves remain absent from many rural areas, particularly in the northern part of the state.
The economic advantages of centerline rumble strips cannot be overstated. Researchers estimate that the benefits of installing these strips outweigh the costs by a factor of 14. With an installation cost of approximately $3,500 per mile, the long-term savings in terms of reduced medical expenses, property damage, and lost productivity are substantial. Even using a conservative service life of seven years, the study demonstrated that rumble strips pay for themselves and provide additional value.
Jhan Kevin Gil-Marin, co-author of the University of Maine study and now pursuing his PhD at Rensselaer Polytechnic Institute, emphasized the importance of continuing to implement these lifesaving measures. Under the guidance of Ali Shirazi, then principal investigator of the Maine Transport Lab, Gil-Marin utilized data from MaineDOT to compare crash rates on similar roads with and without rumble strips. His analysis revealed the true effectiveness of centerline rumble strips in preventing deadly collisions.
MaineDOT remains committed to enhancing road safety through the strategic deployment of rumble strips. The agency aims to add approximately 100 miles of these grooves to state roads annually, prioritizing areas with high traffic volumes and fresh pavement to maximize durability. Funding for these projects comes primarily from the federal Highway Safety Improvement Program, with supplementary support from the state.
While rumble strips focus on infrastructure-based solutions, technological advancements also play a crucial role in improving road safety. Modern vehicles equipped with lane departure warning systems and other sensors offer additional layers of protection. However, as transportation safety researcher Steven Lavrenz points out, human error remains a constant factor. Proactively implementing low-cost safety measures like rumble strips across extensive networks of rural roads could prevent countless accidents before they occur.
As the tax season fades into memory for many, a significant amount of unclaimed refunds remains untouched by Alabama taxpayers. The Internal Revenue Service (IRS) holds millions of dollars that could be claimed by residents who failed to file their returns within the stipulated timeframe. While penalties exist for those who owe taxes but neglect to file, individuals entitled to refunds face no such repercussions—other than losing out on their money. Fortunately, there's still an opportunity for some taxpayers to claim past refunds, provided they act swiftly.
Moreover, taxpayers can retrieve refunds from as far back as three years prior to the current deadline. In April 2024, the IRS reported over a billion dollars in unclaimed refunds due to taxpayers not filing their 2021 returns. For Alabama alone, approximately 18,100 individuals risked forfeiting around $16 million in potential refunds, averaging about $743 per person. Although the window has closed for 2021 refunds, opportunities remain for unfiled 2022, 2023, and 2024 returns. This article outlines steps to recover lost refunds and provides guidance for avoiding future missteps.
Taxpayers who missed filing deadlines for previous years may still have a chance to secure their refunds. Understanding the process is crucial, as the IRS allows claims up to three years after the original deadline. Individuals must gather necessary documentation, including W-2 forms, and ensure accurate submission of past-due tax forms. The IRS offers online resources and assistance to facilitate this retrieval process.
To begin, accessing the IRS Online Account enables users to retrieve essential documents like Forms W-2, 1095-A, and 1099-NEC. These forms provide critical information needed for filing overdue returns. If physical copies are unavailable, requests can be made directly to employers or financial institutions. Additionally, taxpayers unsure of their filing requirements can consult Publication 17, Your Federal Income Tax, available on IRS.gov. This publication clarifies obligations and ensures compliance with federal regulations. By leveraging these tools, Alabamians can successfully reclaim potentially substantial refunds owed to them.
Beyond simply missing filing deadlines, several issues can hinder refund receipt. Misdirected filings, incomplete submissions, or lost checks all pose challenges to obtaining rightful refunds. Awareness of these obstacles empowers taxpayers to take proactive measures against such mishaps. Utilizing digital resources offered by the IRS can streamline resolution processes when complications arise.
For instance, the "Where’s My Refund?" tool serves as a valuable resource for tracking return statuses and confirming refund issuance. Entering specific details such as Social Security numbers, filing status, and expected refund amounts delivers real-time updates regarding pending refunds. However, submitting duplicate filings without proper justification risks complicating matters further. Instead, patience and adherence to IRS guidelines prove more effective in resolving delays. Furthermore, staying informed about available credits, such as the Earned Income Tax Credit, maximizes potential refunds while minimizing future oversight. Through diligence and strategic planning, taxpayers can safeguard their financial interests and optimize their tax experiences.
