Austin Regional ITS Architecture

Needs

The Stakeholders' Needs listed below are designed to answer two basic questions:

What does the System(s) need to do?
What do users need from the System(s)?

They are written from the perspective of a system user or stakeholder in that system and are categorized by the Intelligent Transportation System (ITS) Service Packages that comprise the regional architecture. Service Packages provide an accessible, service-oriented perspective to the overall system architecture used to describe the region or project. They identify the pieces of the physical view that are required to implement a particular ITS service. Each of these service packages has a set of Needs associated with it that can be used as the basis for stakeholder validation, setting proper expectations, and eliciting requirements for the systems and devices to be implemented.
