H-GAC ITS Architecture

Interfaces

A primary purpose of the H–GAC ITS Architecture is to identify the integration opportunities among transportation systems (the ITS elements) in the region. The following table identifies every interface defined for the Houston–Galveston region. Each entry in the "Interfacing Element" column is a link to more detailed information about the particular interface.
