Cooperative Automated Transportation

Roadway safety in a cooperative automated world

Highway automation is not years away, or even days away. It’s here now, causing a number of state transportation agencies to react with initiatives related to preparing and supporting Connected Automated Vehicles (CAVs) on U.S. roadways.


Connected and Automated Vehicles (CAVs)

Cooperative Automated Transportation (CAT) deals with CAVs, which are vehicles capable of driving on their own with limited or no human involvement in navigation and control. Per the definition adopted by the National Highway Traffic Safety Administration (NHTSA), there are six levels of automation (Levels 0-2: driver assistance and Levels 3-5: HAV), each of which requires its own specification and marketplace considerations.


Vehicle-to-Everything (V2X) and Connected and Automated Vehicles (CAVs)

For traffic safety, vehicle-to-everything communications is the wireless exchange of critical safety and operational data between vehicles and anything else. The "X" could be roadway infrastructure, other vehicles, roadway workers or other safety and communication devices. ATSSA members are at the forefront of these technologies, and are working with stakeholders across new industries to see these innovations come to life.


Sensor Technology

CAVs rely on three main groups of sensors: camera, radar, and Light Detection and Ranging (LIDAR). The camera sensors capture moving objects and the outlines of roadway devices to get speed and distance data. Short- and long-range radar sensors work to detect traffic from the front and the back of CAVs. LIDAR systems produce three-dimensional images of both moving and stationary objects.

The American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) on Monday announced the release of  responses to three questions regarding testing of roadway safety hardware under the Manual for Assessing Safety Hardware (MASH), 2016.

The guidance is available online and includes all new and prior questions and answers dating to May 2018.

A joint AASHTO/FHWA technical working group developed the latest responses, which are created to help manufacturers, crash test laboratories and transportation agencies apply the guidelines to roadway safety devices.

AASHTO council unanimously supports resolution to convert MASH into a performance spec

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.
