Cooperative Automated Transportation (CAT)

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.

Roadway fatalities and work zone incidents in 2020 spell concern for roadway safety advocates

NHTSA projects 7.2% increase in motor vehicle traffic fatalities in 2020

Pam 0 8156 Article rating: 4.0

Two reports this month offer stark reminders of the risks of highway work zones and the importance of roadway safety.

Today we look at the latest data from the U.S. Department of Transportation (USDOT) National Highway Traffic Safety Administration (NHTSA), which released its early estimate of motor vehicle traffic fatalities for 2020.

Tomorrow, we will look at results of a survey of highway workers regarding work zone incidents and the issues contractors identified as key to improving safety for employees in work zones.

House Transportation & Infrastructure Committee passes surface transportation authorization proposal

Pam 0 7923 Article rating: 2.5

Early this morning, the House Transportation and Infrastructure (T&I) Committee passed a five-year, $548 billion surface transportation authorization proposal out of committee, mostly on a party-line vote.

Two Republican members of the committee, Rep. Brian Fitzpatrick (R-Pa.) and Resident Commissioner Jenniffer González-Colón (R-Puerto Rico), crossed over and voted with the Democrats. The legislation, named the INVEST in America Act, passed out of the committee after a marathon session that began Wednesday morning and finished around 5 a.m. today. Both Democrats and Republicans offered hundreds of amendments during the process.

This proposal includes funding titles for highways – including roadway safety infrastructure, bridges, transit and passenger and freight rail. By and large, the legislation and the process were derided as partisan by Republican committee members.

ATSSA develops new work zone safety publications under FHWA's Work Zone Safety Grant Program

Pam 0 6548 Article rating: 5.0

ATSSA recently developed three work zone safety publications under the Work Zone Safety Grant Program, which were approved by the Federal Highway Administration (FHWA). The documents include one with a Spanish version and address pedestrian safety and accommodation as well as portable temporary rumble strips application (PTRS) in work zones. 

These new resources are now available:  “Updated Pedestrians Checklist and Considerations for Temporary Traffic Control Zones,” Everyone is a Pedestrian: For a Safe Path Through Work Zones – Don’t Miss Your Cues” and State Examples for the Application of Portable Temporary Rumble Strips (PTRS).”

AASHTO hosting webinars on results of study on converting MASH to performance-based spec

Pam 0 7308 Article rating: 3.0

The American Association of State Highway and Transportation Officials (AASHTO) is hosting two June webinars to review the results of a study commissioned to explore the possibility of converting the Manual on Assessing Safety Hardware (MASH) 2016 to a performance-based specification.

AASHTO hired the Texas A&M Transportation Institute to do a scoping study to assess the effort, timeline and needs required if the change was undertaken. Results of the study will be presented at two webinars, which will include time for questions. Registration is now open.

House Republicans release transportation reauthorization proposal

Pam 0 6468 Article rating: No rating

Republican members of the House Transportation and Infrastructure Committee, led by Ranking Member Sam Graves (R-Mo.), today released their version of a transportation reauthorization ahead of likely Committee action in early June. The language, which is narrower in scope than the House-passed transportation bill last year, would spend $400 billion over five years on federal-aid highway projects, an increase of 32% over current funding levels.

Dubbed the Surface Transportation Advanced through Reform, Technology & Efficient Review Act 2.0 (STARTER Act 2.0), the legislation includes increases to the Highway Safety Improvement Program (HSIP).
