CARMA Overview

Figure 1. Photo. Four cars with the CARMA platform enabled demonstrate platooning ability. This image shows three vehicles on the right traveling in platoon formation along a roadway. A fourth car on the right is getting ready to join the three-car platoon.  Yellow circles on the floor under the vehicles show the cars have connectivity functions. The yellow dotted lines above the cars are connected between each vehicle to show the cars are sending messages to each other. The image has three words listed along a dotted line, innovation, collaborate, and open source mobility.

What Is CARMA?

The Federal Highway Administration (FHWA) developed the innovative CARMASM Platform to encourage collaboration with the goal of improving transportation efficiency and safety. FHWA's interest in advancing Transportation Systems Management and Operations (TSMO) strategies with automated driving technology is focused on how infrastructure can move traffic more efficiently.

CARMA enables Automated Driving Systems (ADS) to navigate more safely and efficiently with other vehicles and roadway infrastructure though communication and cooperation. CARMA was designed using open source software (OSS) and is available on GitHub. The unique platform was created to work collaboratively with any vehicle, hardware, or control system. By simplifying software development and providing access to increased functionality and a community of developers, CARMA enables the research and development (R&D) of cooperative automated driving system (CADS) capabilities to support TSMO. 

CARMA also will develop a concept of operations for new TSMO strategies, such as identifying Traffic Incident Management (TIM) scenarios that provide new strategies for first responder use cases interacting with ADS. This research will accelerate market readiness and the deployment of cooperative automated driving technology, while advancing safety, security, data, and artificial intelligence.

Beyond reducing traffic congestion and improving transportation safety, CARMA will support industry collaboration and expand on existing automation capabilities to reduce R&D time and advance cooperative automated driving technology. CARMA promotes collaboration and participation from communities of engineers and researchers to advance the understanding of cooperative automated driving using OSS and agile project management practices.
