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.

ATSSA joins 100-plus groups urging House members to support infrastructure bill

Pam 0 6792 Article rating: 2.0

ATSSA was among 110 groups today sending a letter to all members of the House of Representatives, encouraging them to vote for the Infrastructure Investment and Jobs Act (IIJA), which passed the Senate in bipartisan action.

The IIJA “represents a historic opportunity to provide substantial economic and quality of life enhancements to communities across the country and to build for the future,” the letter states. “The investments made in the package would facilitate long overdue repairs and improvements to our roads, bridges, rail, and public transportation, and other critical infrastructure, such as airports, ports, broadband, energy, and water systems.”

The infrastructure bill includes a 5-year reauthorization of federal highway, public transportation and passenger rail programs, which the groups note would “ensure states and localities have much-needed funding and policy certainty to proceed with planned projects.”

Those projects are currently operating under a funding extension set to expire Sept. 30.

Preliminary estimates for first half of 2021 show motor vehicle deaths up again this year

Pam 0 7084 Article rating: No rating

Preliminary estimates for motor vehicle fatalities for the first six months of 2021 are up 16% over the same period in 2020, the National Safety Council (NSC) reported this morning.

The estimate for the first six months of 2021 is also 17% higher than the 2019 figures, according to NSC, which tracks that and other data on injuries.

The group noted that mileage for the first half of 2021 was up 13% over the low point in 2020 due to COVID-19. However, this year’s mileage was still almost 6% below travel mileage in 2019.

Roadway Worker Protection Council holds its first meeting

Pam 0 6696 Article rating: No rating

Ideas flowed today as ATSSA’s Roadway Worker Protection Council held its first meeting during the Midyear Meeting in Kansas City, Mo.

Nearly 30 people took part where it was agreed the two primary focus areas are mitigating risk in work zones and creating a support plan to be ready when incidents occur.

Doug Dolinar, who lost an employee to a work zone incident last August, was appointed as council chair  and ATSS Foundation Board Chair Dave Krahulec was appointed as vice chair for today’s meeting. An election of officers will take place when the council meets during the 52nd Annual Convention & Traffic Expo in Tampa, Fla., in February.

The plan is to hold the Roadway Worker Protection Council meeting the morning of Monday, Feb. 14 to avoid conflicts with other council and committee meetings at Convention. The Convention & Traffic Expo will be held Feb. 11-15.

Iowa’s smart use of arrow boards featured in new issue of Roadway Safety magazine

Maria Robertson 0 6732 Article rating: 5.0

In Iowa, arrow boards—a ubiquitous piece of equipment in many work zones—are serving as a testing ground for data-sharing protocols that transportation officials hope will help reduce crashes and fatalities in work zones by providing road users with real-time information of lane closures.

Read about the evolution of smart arrow boards, gain insights from the team at the Institute for Transportation (InTrans) at Iowa State University and learn the role ATSSA member Jeff Koudelka of Iowa Plains Signing Inc. played in the rollout of the roadway safety devices in the Summer 2021 issue of Roadway Safety magazine, available online today.

Survey of highway contractors shows six in 10 reported a crash into their work zone

AGC-HCSS Software Solutions survey includes assessment of dangers

Pam 0 8337 Article rating: No rating

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

Today, we 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.

The Associated General Contractors of America (AGC) and HCSS Software Solutions surveyed highway contractors on their experiences with respect to work zone safety in 2020. Their 2021 Work Zone Awareness Survey Results, which included responses from 292 firms, found that 60% of contractors reported at least one motor vehicle crash in their work zone.
