Traffic Management for Connected Automated Driving (TM4CAD) is a research project focused on the role of infrastructure in supporting autonomous vehicles. The project explores various levels of Infrastructure Support for Automated Driving (ISAD) and how they can contribute to creating an Operational Design Domain (ODD) for Connected Automated Driving (CAD) systems.

In simpler terms, the project investigates how we can utilize infrastructure to provide self-driving cars (CAD systems) with a better understanding of their surroundings (ODD). This is achieved by exploring different methods of sharing environmental information (ODD attributes) between various systems.

The goal is to enable self-driving vehicles to comprehend in real-time where they are permitted to drive and what actions they can take, thus ensuring safe and efficient operation.
