  • MASH update: AASHTO Committee on Design
    At its mid-June meeting, the American Association of State Highway and Transportation Officials (AASHTO) Committee on Design passed a resolution to be balloted by the states urging the organization’s Technical Committee on Roadside Safety (TCRS) to delay the Manual for Assessing Safety Hardware (MASH) implementation dates “until a suitable process can be established to fill the technical role previously filled by the Federal Highway Administration (FHWA), at which time the implementation schedule should be revisited. The resolution does not become “official” until that balloting process is completed. The resolution cited the lack of technical support to researchers and manufacturers developing roadside hardware, the lack of technical expertise by many states to conduct reviews of crash data, and the lack of technical assistance and expertise that has been traditionally provided by FHWA to manufacturers, laboratories, and state practitioners as key reasons for its recommendation. It also stated that a single, national resource for establishing eligibility of safety hardware is preferable, a position that is consistent with that expressed by the Committee on Streets and Highways (chief engineers) at the AASHTO Spring Meeting. TCRS is scheduled to meet on July 11-12 in Austin, Texas. Please note that this is not an open meeting. A full copy of the full resolution is available.
  • FHWA issues interim approval
    In a memorandum released on March 20, the Federal Highway Administration (FHWA) issued “Interim Approval (IA)-21 – Rectangular Rapid-Flashing Beacons (RRFBs) at Crosswalks.” The new IA-21 allows for the optional use of RRFBs as pedestrian-activated visibility enhancements for pedestrian and school crossing warning signs under limited conditions.

  • FMCSA response letter to ATSSA clarifying HOS regulations as applied to roadway striping
    In a Nov. 20 letter to the Federal Motor Carrier Safety Administration (FMCSA), ATSSA President and CEO, Roger Wentz, requested the administration provide clarification of its hours of services (HOS) as they apply to roadway striping operations. Particular clarification was requested in regard to "on-duty (not driving)" status for commercial motor vehicles (CMVs) operating less than 15 mph in a nonpublic work zone.
  • Manual for Accessing Safety Hardware (MASH) Update 2017
    ATSSA’s President and CEO provides an update on the Manual for Accessing Safety Hardware (MASH), covering the history of device testing, key changes and issues surrounding MASH implementation, ATSSA’s efforts to address concerns related to MASH and the current status of ATSSA’s advocacy for the roadway safety industry. This presentation is followed by a video of a presentation given by AASHTO's Director of Engineering and Technical Services, King Gee, at ATSSA's 2017 Midyear Meeting in Louisville, Kentucky.
  • ATSSA Comments on the NHTSA Federal Automated Vehicles Policy 
    In September NHTSA released their Federal Automated Vehicles Policy to the public. NHTSA’s statutory authority is limited to motor vehicles, however, it is important that infrastructure-related objects that interact with the vehicles, such as signage, pavement marking, bicycle and pedestrian safety features, etc., are considered in both NHTSA and FHWA rulemaking regarding Highly Automated Vehicles. While we await FHWA’s proposals for an infrastructure deployment policy, we believe that both sides of automation (auto and infrastructure) must be considered and coordinated when creating these guidelines. ATSSA has just submitted our comments to this policy on behalf of the roadway safety community. These comments are important to potential future regulatory and legislative actions by the federal government.
