CARMA Streets is a component of CARMA ecosystem, which enables such a coordination among different transportation users. This component provides an interface for CDA participants to interact with the road infrastructure. CARMA Streets is also an edge-computing unit that improves the efficiency and performance of the Transportation Systems Management and Operations (TSMO) strategies.
Architecture
CARMA Streets architecture is based on a scalable services and layered architecture pattern that allows for easy deployment. Service components are packaged to contain one or more modules (classes) that represent a specific reusable function (e.g., decode a particular ASN.1 message) or an independently deployable business function (e.g., control interface to a signal controller). Services interact with each other via lightweight messaging service (e.g., Kafka) which allows for them be deployed either together or distributed for scalability and performance. A high-level abstract view of the architecture to communicate the design pattern is shown in Upcoming Figure. A more detailed Unified Modeling Language class and packaging diagrams to define the interfaces between services and layers and their interactions will be developed and documented here during implementation following an Agile Development Methodology.
Deployment
Docker is the primary deployment mechanism to containerize one or more services. The CARMA Streets application and other major frameworks such as Kafka will run in their own separate containers. This document will be updated with a detailed Docker deployment strategy during later design phases.
