2011 Congested Corridors Report and Appendices

You may view the 2011 Congested Corridors Report (1.6MB), including appendices, online.

What are the purposes of this report?

  • We show congestion levels along specific corridors— the level where transportation improvements are determined. The very detailed hour-by-hour data shows when and where congestion occurs.
  • We can suggest how much extra “buffer” time to allow. In addition to average congestion conditions, we include performance measures that describe the unreliability of congested corridors. While you know how long a trip will take on average, what about those days that you have to be on time? This report has a measure for that!
