Interoperable connectivity is the use of a variety of wireless communications technologies to improve situational awareness between vehicles and physical transportation infrastructure as well as pedestrians, bicyclists, and other vulnerable road users. When integrated into a vehicle (cars, buses, trucks, bicycles, motorcycles, etc.) or into infrastructure, these solutions can deliver significant safety improvements and help communities move toward the goal of zero roadway fatalities. These technologies also offer the potential to enhance mobility and reduce transportation’s impact on the environment.
Interoperable connectivity refers not only to the 5.9 GHz spectrum dedicated for ITS communications but other spectrum outside the dedicated 5.9 GHz spectrum that allows for seamless communication between vehicles to everything (V2X) in the transportation ecosystem.
Standards and interoperability are the foundation for interoperable connectivity solutions, as well as security where each message is trustworthy through immediate authentication that includes privacy protection.
Available Resources
The U.S. DOT compiled resources to assist in the deployment of interoperable connectivity projects. These resources are aligned with the systems engineering process to help users find relevant materials based on if they are planning, designing, implementing, testing, or operating and assessing an interoperability project. Access these resources below.
