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.

FHWA issues MUTCD ruling on ‘Uses of and Nonstandard Syntax on Changeable Message Signs’

Pam 0 9614 Article rating: 5.0

The Federal Highway administration issued a Manual on Uniform Traffic Control Devices or Streets and Highways (MUTCD) official ruling this week pertaining to syntax on changeable message sign messaging.

Official Ruling No. 2(09)-174 provides an official interpretation for the question of “whether the MUTCD provides for displays on changeable message signs (CMS) that use unconventional wording typically not found on standard signing and how public input into the development of CMS messages may be used.”

The ruling notes that the devices should not contain advertising or messages unrelated to traffic control and then reviews the five principles for an effective traffic control device: fulfill a need; command attention; convey a clear, simple meaning; command respect from road users; and give adequate time for proper response.
