What is Mosaic (Least Cost Planning or LCP)?
Least cost planning 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."
The Oregon Department of Transportation (ODOT) worked with stakeholders to develop a least cost planning methodology that meets the definition above. Mosaic will enable a more comprehensive evaluation of possible solutions and improve consistency, transparency, and accountability for transportation planning-level decisions.
Mosaic/LCP Project News
Mosaic development and testing are now complete, resulting in a recommended process for using Mosaic in Planning, described in a User Guide, further information and references, and a Mosaic analysis tool built in Excel. These products are now available at Oregon Mosaic while this page has the Mosaic project history and key products from Mosaic's development.
Next, 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.
