Regional Architecture Step Description

This is the first step in defining your Intelligent Transportation Systems project. The portion of the regional ITS architecture that is related to the project is identified. Other artifacts of the planning and programming processes that are relevant to the project are also collected and used as a starting point for project development.

 

Purpose

The purpose of this step is threefold: 

  1. To define the project scope while considering the regional vision and opportunities for integration. Doing this also satisfies the first requirement for system engineering analysis contained in the FHWA Rule/ FTA Policy on Architecture and Standards.

  2.  Improve consistency between ITS projects and identify more efficient incremental implementation strategies. The regional ITS architecture identifies a project sequencing that describes how each project fits within the overall plan for ITS for the region. Beginning the definition of the project with its portion of the regional ITS architecture sets the project into the context of the overall plan and in doing so: 

     

  3.  Improves continuity between planning and project development.

     

Activities

Some of the key activities of this step are:

 

  • Identify regional ITS architecture(s) that are relevant to the project. There may be more than one regional ITS architecture that should be considered.

  • Identify the portion of the regional ITS architecture that applies.

  • Verify project consistency with the regional ITS architecture and identify any necessary changes to the regional ITS architecture.
