Step 2: Establish the Mosaic Framework

Before applying Mosaic, users must understand the Mosaic Framework and key terms (see below). 

The Mosaic Framework

The Mosaic framework is based on the goals and policies of the Oregon Transportation Plan (OTP). The framework includes nine categories for transportation system performance, each with its own objective and set of general and specific indicators, which are the backbone of Mosaic. The nine categories are similar to the evaluation criteria typically established at the beginning of any planning process. Mosaic can therefore help users establish their evaluation framework by providing researched and tested categories and indicators.

Here are some key phrases you will encounter when learning the Mosaic framework.  Note that category and indicator names and terms generally reflect the same meaning as they have in the OTP. (See the glossary for other key Mosaic terms). 

Mosaic Framework Terms

  • Categories of Transportation System Performance: General topics or outcomes against which potential decisions will be evaluated. Performance measures and evaluation methods are proposed and developed under each category. 

  • General Indicators: Aspects of the categories of transportation system performance that will be evaluated, and for which a few measures or indicators are defined. There are two to four general indicators defined for each category of transportation system performance. 

  • Specific Indicators: A measure of performance, described as clearly as possible in terms of scope and unit of measurement. There are one to three specific indicators for each general indicator.
