Mosaic - Value and Cost Informed Planning (Least Cost Planning)

What is Mosaic (Least Cost Planning or LCP)?

Mosaic is Oregon's value and cost informed transportation planning tool, developed by the Oregon Department of Transportation (ODOT) in collaboration with groups of stakeholders representing a diverse range of interests. It offers Oregon transportation planners and decision makers an efficient, transparent way to evaluate the social, environmental, and economic costs and benefits of transportation programs and investments. Mosaic can be used at the local or regional level and is scalable to accommodate varying staff sizes, available data, and unique community needs and goals. Mosaic will enable a more comprehensive evaluation of possible solutions and improve consistency, transparency, and accountability for transportation planning-level decisions.

Least Cost Planning (LCP) was defined by the 2009 Oregon Legislature in the Jobs and Transportation Act (House Bill 2001).

"Least-cost planning means a process of comparing direct and indirect costs of demand and supply options to meet transportation goals, policies or both, where the intent of the process is to identify the most cost-effective mix of options."

Mosaic/LCP Project News

Mosaic development and testing are now complete. The Oregon Mosaic site provides further information, a Mosaic User Guide, and the Mosaic Analysis Tool.

ODOT will continue working with its Region staff and stakeholders to explore opportunities to utilize Mosaic in transportation planning. The test activities showed that Mosaic works and can add value to planning processes. The first few planning projects that use Mosaic will teach us more about how and when it is most helpful and what skills and support are necessary for its successful use.
