“Increase and Maintain Efficiency” is one of the three objectives identified in the Mobility Performance Framework. These objectives specify how WSDOT seeks to achieve Washington State’s desired mobility outcome: To improve the predictable movement of goods and people throughout Washington State, including congestion relief and improved freight mobility.
WSDOT uses two categories of efficiency performance measures:
- Mode Usage: Relative usage of the system relative to capacity (mode share, average vehicle occupancy, load factor).
- Utilization: Usage of the transportation infrastructure or potential users within a travel shed.
