Cooperative Automated Transportation (CAT)

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 urges Congress to include infrastructure policies in CAV legislation

Erica Terrini 0 380 Article rating: No rating

Earlier this month, ATSSA President & CEO Roger Wentz submitted a letter to the U.S. House Energy and Commerce Committee and the Senate Commerce, Science, and Transportation Committee, urging legislators to include infrastructure policies as they draft bills related to Connected and Automated Vehicles (CAVs). 

Automation collaboration: Roadway safety infrastructure and automotive industry connections will pave the way to self-driving vehicles

Erica Terrini 0 876 Article rating: No rating

In recent years, there has been an uptick in collaboration between entities within the roadway safety infrastructure and automotive industries as Connected and Autonomous Vehicle (CAV) technologies progress and enter U.S. roadways. In a sweeping effort to ensure traffic control devices and roadway infrastructure effectively support the Advanced Driver-Assistance Systems (ADAS) of CAVs, manufacturers and groups like the Automotive Safety Council, 3M, SAE International, and ATSSA are working together to uncover the gaps in information and needs to help these vehicles perform at an optimum level. 

Will Connected and Autonomous Vehicles change the landscape of signage standardization?

Erica Terrini 0 1343 Article rating: 5.0

On June 19, 2019 at the National Committee on Uniform Traffic Control Devices (NCUTCD) Connected and Automated Vehicle (CAV) Task Force Meeting, updates on signage and pavement marking uniformity were the main topics of discussion. With CAVs entering U.S. roadways every day, the need for uniformity is growing exponentially. Transformational technologies on CAVs raise new questions for groups like the NCUTCD, such as signage that appears on the exterior of CAVs. For instance, many autonomous vehicles (AVs) manufacturers have their own signage displays on the exterior of the vehicle that alert human drivers and pedestrians of the CAV’s intentions on the roadway.

Highway automation: How ATSSA members play an important role

CAVs will need to better communicate with roadway devices and infrastructure

SuperUser Account 0 836 Article rating: No rating

Connected and Automated Vehicles (CAVs) rely heavily on ATSSA member products such as pavement markings, signs, and traffic control devices. These products will be an essential factor in the advancement of CAVs and critical in moving toward zero deaths on our roadways.
 

Sensor technology in roadway infrastructure

How devices are strengthening the lines of communication between human and automated drivers 

SuperUser Account 0 2183 Article rating: No rating

For many departments of transportation (DOTs), the collection and sending of real-time traffic data to roadway users is high priority. One way agencies nationwide are achieving this goal is through the use of sensor technology in roadway infrastructure, such as pavement markings or signs, allowing them to strengthen Vehicle-to-Infrastructure (V2I) communication.
