Abstract:

The catalog of functions includes a description of a "Basic" computer-based traffic signal system, plus a listing and description of options which can be added. Standardization of the functional requirements of the Basic system, and of the functional requirements for additional features (options), will assist planners and users in the functional design of their systems, as well as assist designers in the design of hardware and software components and modules. Standardization of performance functions, as well as compatibility of equipment that implements these functions, is a major consideration. The catalog of functions contains: (1) A description of the Basic system, plus options; (2) Traffic performance, utility considerations, and cost factors associated with each option; (3) A cross-reference between the catalog of functions and the functional specifications. Functional specifications describe what functions are to be performed, parameters to be measured and/or displayed, and inputs and outputs associated with each function. The functional specifications do not define how each function is to be specifically translated into hardware or software elements.
