Central Puget Sound Freeway Network: Usage and Performance

This report presents a summary of general measures of facility usage (e.g., how many vehicles are transported on the freeway network) and facility performance (e.g., how fast they are traveling , where and how often congestion occurs). These measures are meant to be succinct, yet provide sufficient detail to convey a sense of the complexity of highway performance variations as a function of location, time, and other conditions. In addition this analysis is designed to be repeatable, i.e., the report's contents can be updated periodically with a consistent set of measures so that trends can be monitored over time.
