Needs

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

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.
