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.

    Vehicles equipped with front crash prevention are much less likely to rear-end other vehicles, the Insurance Institute for Highway Safety (IIHS) has found in the first study of the feature's effectiveness using US police-reported crash data. The study found that systems with automatic braking reduce rear-end crashes by about 40 per cent on average, while forward collision warning alone cuts them by 23 per cent. The automatic braking systems also greatly reduce injury crashes.

    When Texas A&M Transportation Institute was asked to devise a temporary traveller information system for work zones, it started by asking drivers what they need. Robert Brydia explains the thinking, implementation and results. US Interstate 35 (I-35) runs roughly north–south originating in Laredo, Texas and ends 1,500 miles away in Duluth, Minnesota having passed through Oklahoma, Kansas, Missouri and Iowa. Within Texas the I-35 splits into I-35E and I-35W passing through Dallas and Fort Worth respectiv
