Crash Cushions Bring Layer of Safety to Interstates

Crash Cushions Bring Layer of Safety to Interstates

 

Trinity Highway News | August 20, 2021

As Tennessee DOT widens and modifies 1-75, including ramps to 1-24, the REACT™ M System was added as an additional safety feature.

The National Safety Council reports that roadway deaths increased during 2020 even though the number of miles driven decreased. Departments of transportation are looking for ways to reverse these numbers for 2021 and beyond.

The Tennessee Dept. of Transportation (TDOT) is in the midst of a design-build interchange modification on I-75 at I-24 under the direction of general contractor C.W. Matthews Contracting Co. The REACT™ M system, which recently received Federal Highway Administration (FHWA) eligibility, was selected by TDOT to bring an added layer of safety to the project. Site-Safe, LLC distributed and oversaw the installation of the REACT M in March.

The REACT M is a redirective, non-gating crash cushion that consists of six high-density polyethylene cylinders per unit attached to a steel backup and base-track assembly. It is tested to MASH 16 Test Level 3. The REACT M includes a self-contained backup structure that is designed to resist movement during head-on and side impacts and can protect hazards up to 30-in. wide. The system has shown self-restoring characteristics when impacted within MASH 16 crash test standards.

C. David Rich, president of Site-Safe located in Leitchfield, Ky., says, “The first version of the REACT (REACT 350) was invented at Vanderbilt University in Nashville and accepted by FHWA, both in 1995. It is only fitting that the latest version of the REACT (REACT M) had its first install in Tennessee, the state where it all started. With the recent FHWA eligibility, we now expect to see many more REACT M installations in both permanent and work-zone applications throughout the U.S.”

Back-Of-Queue Warning Trucks in Efforts to Improve Work Zone Safety

Trinity Highway | April 2021

With more than $2B slated for roadway maintenance and construction projects across the state of Indiana in 2021, the upcoming road construction season promises to be a busy one. And along those freshly paved roads, Hoosiers will be seeing lots of back-of-queue warning trucks like the SS180®M, also known as truck-mounted attenuators or TMAs.

 

The SS180®M TMAs, manufactured by Trinity Highway, were shown to the general public during a Work Zone Safety Showcase at the Robert D. Orr Plaza near the Indiana Statehouse on Monday, April 19.  Site-Safe, LLC and The Hoosier Company, Inc. supplied the SS180®M TMAs on display at the showcase.

“Partnership across the road construction industry is what it takes to make this record-breaking construction season a safe one.”

Hope Tollett, Fleet Manager at Site-Safe, LLC

Indiana Department of Transportation (INDOT), in conjunction with road construction contractors, state police, and safety equipment suppliers, hosted the Work Zone Safety Showcase to highlight new safety measures being implemented to help reduce the risk of crashes in work zones and make them safer for road construction crews.

 

“The Hoosier Company as a partner with INDOT is excited to see technology be used in the work zone to reduce back of queue crashes. The highway construction industry is all in this together to make sure everyone on the Indiana roadways makes it home safely to their families.”

Josh Coulter, Director of Highway Safety Products, The Hoosier Company

The SS180®M equipped back-of-queue warning trucks, automated queue warning systems, and the connected technology alert system are part of a three-pronged approach to improve work zone safety by combining equipment with technology solutions. The SS180®M will be fitted with high visibility warning lights and portable message boards designed to warn motorists to prepare to slow down or stop when approaching a work zone.

“Site-Safe is honored to partner with INDOT by utilizing connected technology on our entire fleet, which provides notification to drivers ahead of construction zones, ultimately saving lives.” 

                                             – Hope Tollett

In 2019, Indiana formed a task force to research and test various solutions to improve work zone safety.  The Protect the Queue program – which pairs two queue trucks ahead of a backup to alert motorists to an upcoming backup so that drivers can begin to slow their speeds in advance of the queue, was developed out of this initiative and piloted in 2020.

 

In addition to the Protect the Queue program, INDOT offers the Hoosier Helpers program to assist stranded motorists. It also works closely with research institutions like Purdue University and the Joint Transportation Research Program to evaluate new solutions. The Hoosier Company has been active with various aspects of the three INDOT programs.

“The Protect the Queue program has increased visibility of backups and reduced severe rear-end collisions,” said Coulter. “Everyone would like to see zero deaths in our work zones this season.”

Two New Products Improve Safety in Highway Construction Work Zones

Two New Products Improve Safety in Highway Construction Work Zones

Trinity Highway News | March 2020

 

Two New Products Improve Safety in Highway Construction Work Zones

An industry leader and global supplier of commercial highway products, Trinity Highway recently added two new products that comply with the Manual for Assessing Safety Hardware (MASH) for testing standards accepted by AASHTO and FHWA.

They are the SMT™ and the SS180®M.

Both are truck/trailer-mounted attenuators (TMAs) that can be attached to the rear of a stationary or moving shadow support vehicle.

The two products are tested to MASH Test Level 3 and are designed to help absorb rear-end impacts at speeds up to 62 mph (100 km/h) when impacted within MASH crash test standards.

SMT is a trailer-mounted attenuator for efficient deployment. Its system is comprised of two lightweight aluminum cartridges contained in a steel support frame. It has LED lighting, replaceable energy-absorbing cartridges, and a potentially reusable steel frame after an impact within MASH crash test standards.

The SS180 M is a truck-mounted attenuator consisting of two lightweight aluminum cartridges contained in a potentially reusable steel support frame. It is designed to help minimize damage from low-speed nuisance hits up to 6 mph.

Tennessee Major Highway Project Gets Approved Safety Boost

 

Tennessee Major Highway Project Gets Approved Safety Boost

 

Trinity Highway News | April 2016

 

In January 2016, the Federal Highway Administration (FHWA) encouraged implementation of Manual for Assessing Safety Hardware (MASH) roadside products by announcing sunset dates for NCHRP Report 350 products. Contractors in Tennessee were encouraged to consider MASH crash cushions along with 350 other systems last July in Lawrence County on Project NH-15 (180). This 5.7-mile paving project on U.S. 64 involved a bypass for S.R. 15, base, paving, guardrail and markings. Average daily traffic on this 70-mph roadway is currently 4,600, and is expected to increase to 5,500 by 2034.

 

According to Ali Hangul, P.E., CPESC, assistant director of the Tennessee Department of Transportation (TDOT), “Our top priority is the safety of the motoring public. Immediately after MASH was published, the design division began evaluating how to implement MASH. The division is continuously updating the TDOT Qualified Products Lists (QPL) to include manufacturers that have tested their safety hardware under MASH criteria and have received an eligibility letter from the FHWA. The QuadGuard M10 MASH-Complaint Crash Cushion was the first attenuator product line to complete testing under MASH criteria. As of January 2016, the department is allowing only MASH-compliant safety hardware to be included on the QPL. As the implementation dates provided by the FHWA are reached, existing NCHRP 350-compliant safety hardware on the QPL will be removed.”

 

Project NH-15 (180) called for narrow-low maintenance crash cushion systems, as well as a wide-low maintenance system for permanent installations. Although MASH units were not specifically called out for this project, TDOT’s QPLs included several MASH units that would be acceptable. Site-Safe LLC of Leitchfield, Ky., the crash cushion installer, quoted Trinity Highway’s QuadGuard M10, which consists of an engineered steel nose and crushable, energy-absorbing cartridges surrounded by a framework of steel quad-beam panels. The system is MASH Test Level 2 and Test Level 3 compliant as a re-directive, non-gating crash cushion. TDOT agreed to the use of the system. Once assembled in its yard, the units were easily transported and dropped into place and anchored, minimizing installation time on the roadside. Installment of the MASH systems was in accordance with TDOT specifications and additional MASH roadside systems will be added to Tennessee’s roadways in the future.

“It’s comforting to know that we have agencies such as TDOT procuring roadside safety hardware that meet the latest standards in the industry” said Site-Safe President David Rich.
