Project Approach
The City embarked upon the first comprehensive study of their existing traffic management systems using a methodical process known as the Systems Engineering Process. This proven process has been used extensively on studies such as this project because it works through a series of steps starting with the identification of the project goals and objectives. Based upon the goals and objectives, the project needs, requirements, and overall implementation plan is developed. This process matches technology to the needs of the community.
As shown in Figure 1, the Systems Engineering “V” Diagram suggests an interdisciplinary approach to developing systems and, through checkpoints back to the starting line, ensures that what is ultimately designed and deployed meets the project intent. The Systems Engineering process is tailored to focus on defining stakeholder needs and required functionality early in the development cycle, documenting requirements, then proceeding with design and system validation while considering the “big picture.”

It is critical that the planned intelligent transportation system (ITS) reflects a reasonable and comprehensive project that meets the needs of the project stakeholders. The needs identified through the various workshops were used to identify system requirements that guided the design and the development of the implementation plan.
