In the transportation planning process, strategies are the approaches that are used to achieve the objectives. ITS strategies are represented in the Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT) by Service Packages (previously known as Market Packages). Service Packages are the units of implementation that represent programs or projects that might be implemented in a region. The relative influence of each of the Service Packages in advancing the ITS Goals is shown in the table below. Select a Service Package to see the collection of components that make it up and additional information about how it relates to the goals, objectives, and performance measures defined in the planning process. Note that the table below has been extensively updated from the previous version of ARC-IT (National ITS Architecture v7.1) to include the connected vehicle related service packages, which provide an array of new strategies that regions can consider.

Architecture Use

The objectives-driven, performance-based approach for planning for operations and the regional ITS architecture process have complementary strengths. The architecture development process begins with an understanding of regional needs and the current state of the transportation system based on input from a broad coalition of stakeholders. It results in a planning framework (the regional ITS architecture) and a sequence of integrated projects that implement a portion of that framework. The strength of the regional ITS architecture process is its development of an integrated view of the regional transportation system based on a set of identified services or strategies. This complements the planning for operations process, where the focus is on defining the most effective strategies for a region based on high-level goals and operational objectives. By connecting the two processes, you combine the strong basis for selecting strategies in planning for operations with the strength of the architecture development process in defining an integrated framework based on selected services. To take advantage of this synergy, you need to connect the ITS services in the regional ITS architecture with the strategies defined in transportation planning. The menu of ITS services presented on this web page is one way to make this connection.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.
