Functions

"Functions" are a description of WHAT the system has to do.  In the National ITS Architecture, functions are defined at several different levels, ranging from general subsystem descriptions through somewhat more specific equipment package descriptions to Process Specifications that include substantial detail.  The equipment packages or "functional areas" that are associated with one or more elements in the California Statewide ITS architecture are listed below.  Each functional area is a link to more detailed information, including the portion of the California Statewide ITS Architecture that implements the function, and the more detailed functional requirements that are applicable.
