H-GAC ITS Architecture

Skip to main content

Functions

All elements within the H–GAC ITS Architecture fall under a subsystem, such as emergency management center or transit vehicle, and each of these subsystems is associated with one or more functional objects. These functional objects have a set of requirements that describe their functionalities and can be useful in developing requirements for future projects. Detailed descriptions of all functional objects, as well as the elements and requirements associated with them, are provided in the links included in the table below.
