Congestion & multimodal mobility reports

Find information on annual multimodal mobility and congestion trends and learn how COVID-19 has affected our travel trends.

Following an extensive stakeholder engagement process, we replaced the Corridor Capacity Report with the interactive Multimodal Mobility Dashboard. The 2021 Multimodal Mobility Dashboard (MMD) provides annual multimodal mobility performance information on select state-owned facilities through a user-friendly format and expanded areas of analysis.

What is the Multimodal Mobility Dashboard? 

The MMD focuses on the state’s most-traveled commute corridors, analyzing congestion and the strategies used to mitigate it—including public transportation and our Incident Response program. Where data is available, the MMD also analyzes multimodal freight mobility as well as travel by passenger rail, ferry, airplane, and walking and biking. The most recent annual data available for most measures is for 2020. 

Multimodal Corridor Capacity Report

The annual Multimodal Corridor Capacity Report (the predecessor to the Multimodal Mobility Dashboard) was published annually from 2007 through 2018. The past five years are listed below (as well as a story map for 2018). We can provide earlier PDF editions by request.  

COVID-19 Multimodal Transportation System Performance Dashboard

The COVID-19 Multimodal Transportation System Performance Dashboard is updated daily to help analyze transportation trends that have occurred since the pandemic started. The dashboard provides data and information on systems ranging from state highways, ferries and tolling facilities to active transportation, rail and aviation.
