Abstract:

The Federal Highway Administration’s (FHWA) Cooperative Driving Automation (CDA) Program, formerly known as the CARMA℠ Program, is an initiative to enable collaboration for research and development of CDA technologies. The CDA Program develops and maintains an ecosystem of open-source software tools, which together are known as the CARMA Ecosystem, to enable CDA research. The CARMA Ecosystem is a research environment that enables communication between vehicles and roadside infrastructure devices to support coordinated movement to improve safety, traffic throughput, and energy efficiency of the transportation network.


In 2015, the FHWA’s Office of Operations Research and Development developed a cooperative adaptive cruise control proof-of-concept prototype that was installed in five research vehicles. From there, the CARMA Ecosystem further evolved through testing and integration. At the time of this writing, the CDA Program is advancing into automated driving systems that leverage infrastructure to support cooperative automation strategies. This project expands CARMA functionality to include transportation systems management and operations (TSMO) strategies on surface arterials with intersections.
