	Information on the Performance Overview This page shows the hi-lights of three key highway system performance measures: 1. Congestion at Various Interstate Locations, 2. HOV Travel Speeds, and 3. Travel Times on Key Commuter Routes. Each measure has its own set of data and rules, and should be opened up individually for more detailed information. You can open a measure up by either selecting it from the drop-down list (shown as “Choose Measure”), or just click in the title box for the measure. There are two additional measures available by using the drop-down list that are not shown on this Overview page – Incident Duration, and Annual Hours of Delay.
