AASHTO’s Council on Highways and Streets voted Wednesday to support a resolution to convert the Manual for Assessing Safety Hardware (MASH) to a specification.

The vote took place during the Council’s meeting as part of AASHTO’s annual meeting in San Diego.

AASHTO maintains MASH and commissioned the Texas Transportation Institute (TTI) to conduct a scoping study on the idea of converting MASH 2016 to a specification. The study was completed this year, according to a presentation by Maine Department of Transportation Chief Engineer Joyce Taylor, who serves as vice chair of AASHTO’s Committee on Design. The association also held two webinars in June with state and industry officials to address opportunities and challenges the conversion would bring.

The move to convert MASH into a performance specification is aimed at “developing a more consistent testing of roadside hardware,” according to the Council on Highways and Streets resolution.

ATSSA filed a friend of the court brief in support of the Intelligent Transportation Society of America (ITS America), the American Association of State Highway and Transportation Officials (AASHTO) and the Amateur Radio Emergency Data Network (AREDN), which are appealing an order by the Federal Communications Commission (FCC) to reallocate a portion of the 5.9 GHz spectrum band to unlicensed uses including WiFi.

The FCC voted unanimously on Nov. 18, 2020 to reallocate more than half of the safety band. The new rules adopted by the FCC make the lower 45 megahertz (MHz) of the spectrum available for unlicensed uses and require Intelligent Transportation System (ITS) licensees to stop using that portion of the spectrum within a year.

The FCC’s action came despite warnings from the U.S. Department of Transportation (USDOT), U.S. Department of the Treasury and multiple transportation-safety-focused organizations including ATSSA.

During AASHTO's 2021 Virtual Spring Meeting on Monday, the Council on Highways and Streets (CHS) gathered to provide updates from various stakeholders. The discussion included an update on the Manual for Assessing Safety Hardware (MASH) scoping study to determine the feasibility and potential next steps to convert MASH into a set of performance specifications.

Joyce Taylor from the Maine Department of Transportation (MaineDOT), who serves as design vice chair with AASHTO, gave an update on the MASH scoping study conducted by Texas A&M Transportation Institute (TTI). She discussed the challenges related to current testing procedures and the gray areas within the existing manual that lead to a lack of consistency, as testing may be conducted differently by facilities.

The scoping study, conducted by TTI and sponsored by AASHTO, was completed in April.

Information is now available that clarifies issues related to implementing the 2016 edition of the Manual for Assessing Safety Hardware (MASH).

The American Association of State Highway and Transportation Officials (AASHTO) publishes MASH and issued the latest updates in a Question-and-Answer format. The latest information is the result of work produced by a joint technical working group of people from state departments of transportation (DOTs), the Federal Highway Administration (FHWA) and accredited crash testing labs, according to a statement included in the release.

The latest COVID-19 relief package passed by Congress included nearly $10 billion in federal funds for transportation as reported here last month. The vast majority of that money--$9.8 billion—will go to state departments of transportation (DOTs) across the country.  

Industry publication Construction Dive has now gathered details of the amounts expected to go to each state DOT as well as the DOT for the nation’s capital, and created a chart detailing the allotments. Its report also details how the money will be allotted and indicates that the Federal Highway Administration (FHWA) is to distribute the funds within 30 days of the bill’s signing by former President Donald Trump, which took place Dec. 27.
