OpenCDA is a generalized framework for prototyping cooperative driving automation (CDA; see SAE J3216) applications (e.g., cooperative perception, platooning) as well as automated driving components (e.g., perception, localization, planning, control) integrated with automated driving simulation (CARLA), traffic simulation (SUMO), and Co-simulation (CARLA + SUMO). OpenCDA builds upon standard automated driving system (ADS) platforms and focuses on various classes of data exchanges and cooperation between vehicles, infrastructure, and other road users (e.g., pedestrians).

The goal of the OpenCDA project is to enable researchers and engineers to prototype any cooperative driving applications using our full-stack CDA platform and test them from both automated driving and traffic operations perspectives. OpenCDA bridges the gaps between the communities of automated driving and transporation engineering. Eventually, OpenCDA can be used to develop and test cooperative driving functions and applications for improving safety, sustainability, and efficiency of future transportation systems.

The key features of OpenCDA are:

• Full-stack CDA System: OpenCDA provides a full-stack automated driving and cooperative driving software system that contains perception, localization, planning, control, and V2X communication modules.
• Connectivity and Cooperation: OpenCDA supports various levels and categories of cooperation between CAVs in simulation. This differentiates OpenCDA with other single vehicle automation tools.
• Integration: OpenCDA utilizes CARLA and SUMO separately, as well as integrates them together for realistic scene rendering, vehicle modeling, and traffic simulation. It is also efficient and flexible enough to be applied for software-in-the-loop and hardware-in-the-loop testing.
• Modularity: OpenCDA is highly modularized, enabling users to conveniently replace any default algorithms or protocols with their own customzied design.
• Benchmark: OpenCDA offers benchmark testing scenarios, benchmark baseline maps, state-of-the-art benchmark algorithms for ADS and Cooperative ADS functions, and benchmark evaluation metrics.

Users could refer to OpenCDA documentation for more details.

OpenCDA consists of three major component: Cooperative Driving System, Co-Simulation Tools, and Scenario Manager.

The current version features the following:

• OpenCDA v0.1.0 software stack (basic ADS and cooperative ADS platform, benchmark algorithms for platooning, cooperative lane change, merge, and other freeway maneuvers)
• CARLA only simulation
• Co-Simulation function with CARLA + SUMO
• Scenario manager and scenario database for CDA freeway applications

Future versions are expected to include the following:

• OpenCDA v0.2.0 and above software stack, including signalized intersection and corridor applications, cooperative perception and localization, enhanced scenario generation/manager and scenario database for newly added CDA applications)
• SUMO only simulation which includes SUMO impplementation of all cooperative driving applications using behavior based approach (consistent with CARLA implementation)
• Software-in-the-loop interfaces with two open-source ADS platforms, i.e., Autoware and CARMA
• hardware-in-the-loop interfaces and example projects with a real automated driving vehicle platform and a driving simulator
