Mobility

The Mobility Performance Framework (MPF) provides guidance on how to assess mobility in order to achieve the state’s transportation system mobility goal: To improve the predictable movement of goods and people throughout Washington State, including congestion relief and improved freight mobility (Washington State Legislature, RCW 47.04.280, Transportation system policy goals).

Key Elements of the Mobility Performance Framework

A key intent of the Mobility Performance Framework (MPF) is for it to be scalable across the entire range of tasks that WSDOT undertakes. A guide for selecting and analyzing performance measures for different project tasks is provided elsewhere on this website on the Choose by Project Task page.

The specific performance measures and metrics identified for the MPF are organized under three objectives: 

The performance measures on this website are intended to be useful for a wide variety of project types and contexts. However, there are many potential approaches to evaluating how WSDOT investments and partnerships may affect the transportation system. The performance measures presented here are a starting point for analysts.
