ITS Architecture

ITS Architecture With Key Stakeholders

ITS Architecture
ITS architecture is not a system design nor is it a design concept. It defines the framework around which multiple design approaches (e.g., regional architectures) can be developed, each one specifically tailored to meet the individual needs of the user, while maintaining the benefits of a common architecture. A simple example of what the architecture is trying to accomplish can be visualized by considering how stereo systems work. Stereo systems consist of different components: receivers, speakers, CD players, DVD players, etc. Components can be produced by different manufacturers with each offering distinctive features. However, by having standard inputs, outputs, and connecting cables, a person can mix components and manufacturers without worrying if they are compatible.

National ITS Architecture Conformity
Nationally, the transportation community is investing billions of dollars in ITS and there are concerns about the ability of local ITS systems to communicate with each other and share information. To address this problem, the US DOT created the National ITS Architecture to provide a common framework for planning, defining, and integrating intelligent transportation systems.

The national architecture identifies and specifies requirements for ITS standards needed to support national and regional interoperability. To fulfill the congressional mandate of ITS conformity, the US DOT has recently issued ITS regulations and will shortly issue additional rules to foster integration of ITS into the transportation planning and project development processes.

Regional ITS Architecture
USDOT’s ITS conformity regulations require development of a regional ITS architecture to serve as the basis of regional integration. DVRPC has developed the Regional ITS Architecture for the Delaware Valley through a coordinated process with a wide array of stakeholders. This effort was guided by the ITS Technical Task Force and conducted in accordance with guidance set forth by US DOT in the National ITS Architecture. The Regional ITS Architecture for the Delaware Valley addresses:

• The integration of ITS systems and components
• The roles and responsibilities of a wide range of ITS stakeholders
• The tailoring of ITS deployment and operations to local needs
• Inventory of Existing Regional ITS Resources
• The sharing of information between stakeholders
• The future expansion of ITS.
