picture_as_pdf AGC Survey: Over 50% of Highway Contractors Experience Work Zone Crashes 2018. "Over Half of Highway Contractors Experience Work Zone Crashes, AGC Survey Finds A national survey of 550 highway contractors conducted by the Associated General Contractors of America found that 54 percent of them said motor vehicles crashed into their construction work zones during the past year. On top of that, 48 percent of contractors who experienced work zone crashes reported injuries to either motor vehicle operators or passengers, while 24 percent of those crashes involved a driver or passenger fatality."
picture_as_pdf Crane and Bucket for Mobile Barriers MBT-1 World Highways – Sept 2017. "The crane enables work crews to conduct activities such as guard rail and crash cusion replacement efficiently in a safe environment. This reduces the need for additional safety assets, cuts down operational times onsite and minimises lane closures. The barrier can also be rapidly deployed as an incident management device. The high walls of the MBT-1 minimises the 'rubbernecking' that occurs when motorists drive past incident scenes, often creating secondary incidents."
picture_as_pdf Mobile Barriers: Helping Save Lives WSDOT Mobile Barrier Hit – Sept 2016. "Thankfully no one was hurt when an out-of-control vehicle crashed into a mobile barrier and not the crew replacing concrete panels on the highway. The driver was arrested and charged with 32 counts of reckless endangerment, one charge for each person working on the highway that night, and DUI."
TxDot Facebook Post and Comments Fort Worth Crews using MBT-1 – July 2016. "Fort WOrth District maintenance crews are taking advantage of the latest safety tool - our mobile barrier. The district was one of the first to use the mobile barrier at TxDOT as part of a pilot program . The pilot program was a huge success, so TxDOT purchased mobile barriers to be used in other areas. The mobile barrier is made of high grade steel which allows crews to set up an operation for a short time, make the repair, then move to another repair site."
picture_as_pdf Blame vs Protection Modern Contractor Solutions – Jun 2015. "Last year, more than 32,000 people lost their lives in motor vehicle accidents. Hundreds of thousands more were involved in accidents. In highway construction work zone areas, thousands of fatalities and injuries are reported on an annual basis. While much of the focus in work zones has been on the loss of life or seious injuries for the workers themselves, a recent study by The Associated General Contractors of America (AGC) shows that the traveling public is also at great risk; nine out of ten work zone accidents involve the traveling public. With the significant impact of work zone accidents on motorists and passengers, the question arises as to whether State DOTs are doing all they can to save lives and eliminate injuries."

picture_as_pdf Road User Costs Modern Contractor Solutions – Feb 2015. "If maintenance operations are planned for an interstate with an ADT greater than or equal to 60,000 vpd, it would be better to conduct the work during non-peak periods and protect workers with a mobile barrier system so that the lanes could be returned to vehicle use during peak hours. Likewise, significant road user costs for two and three remaining lanes open begin to occur at 120,000 vpd and 180,000 vpd, respectively. Overall, the information in Table 1 shows that road user costs are important to consider with maintenance operations."
picture_as_pdf “The Perfect Tool” – Mobile Barriers MBT-1 New Construction Products – Nov/Dec 2015. "The MBT-1 has proven particularly efficient for various types of work where protection has not traditionally been practical and where setup/breakdown has sometimes taken longer than the work itself. In some instances, crews are doing in one night what had otherwise taken three to five. In the DC area, crews have cut the time for certain types of ongoing work by 66 percent, with better response times and productivity. In Colorado, crews have replaced 42 sticks of guardrail in the time it normally takes to do six to eight (one night). On Staten Island, they replaced bridge rail in half the anticipated time. In each case, the barrier is simply driven to site, and from site to site, as needed. These and other projects such as chip seal, pothole repairs, slab replacement, ITS installations and maintenance, as well as bridge and tunnel work (bridge joint, bridge deck, tunnel maintenance and repairs), often involve discrete work areas and multiple locations in a given day or night. For such work, the barrier is particularly useful and what has been called “cheap insurance.” The barrier has stopped a direct rear impact without damage (only the TMA needed be replaced). On two occasions, the MBT-1 has turned and safely redirected semi-trucks with only nominal damage."
picture_as_pdf Caltrans deploys Mobile Barriers MBT-1 MBT-1 used for ongoing road and bridge work – Dec 2014. "The California Department of Transportation (Caltrans) in the US has deployed Mobile Barriers MBT-1 for ongoing road and bridge work in a bid to improve safety and efficiency of crews."
picture_as_pdf Work Zone Safety Solutions on Busy World Highways World Highways – Oct 2013 Shortly after publication, the MBT-1 barrier featured in this article was hit from the rear at high speed preventing an errant vehicle from crossing directly through a work zone. Everyone was OK and the barrier was fine. Within a couple days, the barrier was back on the job with a new TMA. We know many of the people that work behind the barrier and are most happy that they (as well as the errant driver) remained safe.
picture_as_pdf Case Study for Highly Efficient & Cost Effective Guardrail Maintenance "With Mobile Barriers MBT-1, there is no need for the separate light plants, generator, truck and trailer to haul rail and post, or air compressor, as these are all provided and carried on-board. As repairs are completed, the trailer (the entire work zone) is simple driven forward, thus allowing 42 plus pieces of rail
to be replaced in the same 8 hour lane closure. What would otherwise have been a week of lane closures, equipment and labor costs, safety exposure, and traffic congestion, was completed in one night. Similar safety and cost saving efficiencies can be applied to concrete bridge deck slab replacements, concrete barrier and bridge rail repairs, bridge inspections, roadway repairs, ITS maintenance and other activities."

supplement the Policy Directive Work Zone Safety and Mobility Policy 805.0 and comply with the Federal Highway Administration Final Rule Subpart K to CFR Part 630."
