scope:

The present document prepares the specification of the Collective Perception Service [i.1] to support applications in the domain of road and traffic safety applications. Collective Perception aims at sharing information about the current driving environment with other ITS-Ss. For this purpose, the Collective Perception Service provides data about detected objects (i.e. other road participants, obstacles and alike). Collective Perception reduces the ambient uncertainty of an ITS-S about its current environment, as other ITS-Ss contribute context information. This includes the definition of the syntax and semantics of the Collective Perception Service (CPS) and detailed description of the data, the messages and the message handling to increase the awareness of the environment in a cooperative manner.
