5948 Easi-Set Worldwide has announced that its J-J Hooks barrier system has successfully passed both bolted-down and pinned-down MASH Test Level 3 crash tests (MASH - Manual for Assessing Safety Hardware), out-performing other comparable systems. The tests were performed by the 232 Texas Transportation Institute.

Prior to these tests, over 41 states/provinces and eight countries have approved the free-standing J-J Hooks temporary barrier for use on their highways. This temporary barrier successfully passed NCHRP 350 TL3 tests in the 1990’s, qualifying it for approval as an alternate to existing state/provincial standard barrier designs. Easi-Set is identifying this barrier as J-J Hooks/NCHRP.

The anchored J-J Hooks design, dubbed J-J Hooks/MASH, incorporates an enlarged J-Hook, additional reinforcing to absorb the higher impact loads, and patented deflection limiting blocks.

Both designs connect seamlessly to each other and they can be placed in the same installation without the need for a transition section. This allows one installation to satisfy up to three different performance requirements. Both J-J Hooks designs are available in cross-sections commonly used on existing highways.

    The type-approval of roadside drug testing equipment could bring about fundamental changes to the way police tackle the problem as Colin Sowman finds out. It has been almost 50 years since the first drink-driving laws were introduced but the problem persists: the European Commission estimates that 25% of road fatalities in the EU are the result of alcohol consumption. Statistics from the UK show that 20% of drivers killed in road accidents in 2012 were over the blood alcohol limit for driving.

With ITS, C-ITS and V2X technology progressing at such a pace, predicting the future is more akin to trying to nail three jellies to the wall – but only having one nail. And yet with roadways having a lifetime measured in decades, that is exactly what highway engineers and traffic planners are expected to do. Fortunately, New Hampshire DoT (NHDoT) believes its technological advances may be able to provide a solution. The Central Ne
