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.

    A new report carried out by Parsons Brinckerhoff on behalf of the DC Department of Transportation (DDOT) finds that speed cameras are helping to reduce accidents and injuries and slowing drivers down. The DDOT conducted an engineering study to determine a link between traffic safety and placement of automated speed enforcement devices (speed cameras) in the District of Columbia. As part of this study, Parsons Brinckerhoff and its team members conducted speed and volume studies, carried out field assessme

Figures from various sources indicate that road accidents are the second most frequent cause of death for on-duty fire fighter fatalities and that more than 90% of ambulance and fire engine accidents occur when the lights are on and the sirens wailing.

But designers and engineers are grappling with a number of difficult issues, muses Chris Hayhurst of MathWorks Earlier this year, the UK government made the bold statement that by 2021, driverless cars will be on the UK’s roads. But is this an achievable reality? Driverless technology already has its use cases on our roads, with levels of autonomy ranked on a scale. At one end of the spectrum, level 1 is defined by th
