Functional Requirements

In some cases, Bay Area ITS project sponsors have existing documentation of the functional requirements used to design and/or procure their systems or project components.  In cases where project sponsors have provided this documentation, it is posted along with a brief description.  It is important to note that this documentation does not necessarily represent the 'as-built' list of functionality of these projects, nor does it represent the requirements of future project partners in connecting or coordinating with these projects.  

Examples of Current Bay Area Projects

Sample Functions of Typical ITS Projects

Planning and design of ITS projects requires a clear and concise description of what the projects will accomplish when implemented. The sample functional requirements in the Bay Area ITS Architecture can provide  stakeholders with a tool to assist in defining  high-level goals, objectives, and required functions.  The functional requirements provided in this Architecture can be used as a tool to develop actual requirements for projects that meet the specific needs of the project sponsors.

When conducting design and preparation of procurement of documents, stakeholders should refer to the high-level functional requirements and examine the detailed functional description provided by the National ITS Architecture in the context of each project’s specific objective to develop specific functional requirements that reflect the needs of the corresponding stakeholders. Project sponsors may choose to add these requirements to their projects in order to further regional goals and supplement the project-level requirements. 

The sample functions provided in this section are not requirements to be placed on projects or project sponsors.
