FHWA Grows Its CARMA[SM] Vehicle Fleet by Four.
The U.S. Department of Transportation is committed to facilitating this new era of transportation innovation and safety. To this end, the Federal Highway Administration developed the Cooperative Automation Research Mobility Applications Platform[SM] and CARMA Cloud[SM] (collectively referred to as CARMA[SM]). CARMA supports the research and development of CDA features in support of transportation systems management and operations (TSMO).
Enabling Cooperative Driving Automation
CARMA is a multimodal effort among FHWA, the Federal Motor Carrier Safety Administration, the Intelligent Transportation Systems Joint Program Office, the Maritime Administration, and the Volpe National Transportation Systems Center. Together, the agencies work to facilitate collaboration, research, and testing in cooperative automation.
The CARMA Platform enables cooperative research functionality for an automated driving system. CARMA Cloud makes it possible for the roadway to provide information to support safe operation for new TSMO strategies.
Developed to be vehicle and technology agnostic, CARMA uses open-source software and an agile software development process. The latest version of CARMA is available on GitHub, a web-based repository and version control system for computer code that includes features for code review, documentation, and collaboration. CARMA supports industry collaboration and expands upon existing automation capabilities to reduce research and development time and advance cooperative automated driving technology.
Automated Vehicles Working Together
Over the summer, FHWA added four new passenger vehicles to its CDA fleet. These vehicles use the third phase of CARMA (CARMA3), which was released in mid-July 2019. CARMA3 features:
* Autoware[TM], open-source software designed for autonomous driving, which provides capabilities for localization, motion planning, and obstacle detection and avoidance.
* Mobileye[R]-integrated roadway sensing devices, as well as environment sensing with light detection and ranging (LiDAR), radar, and video.
* Level 2 automation steering and speed control while maintaining lane position. Basic safety message (BSM) broadcasts using CARMA data.
* Operation on three different types of passenger vehicles with three different brands of controller modules.
The CARMA3 vehicle fleet includes two sport utility vehicles, one minivan, and one mid-size sedan. These four vehicles expand FHWA's testing capabilities and demonstrate how connected automated vehicles can work together through communication and cooperation. The vision of CARMA is to transform transportation, improving efficiency and safety through automated vehicles working together.
The CARMA3 vehicles will hit the road in 2020 to conduct further research, testing, and demonstrations.
