Return to Offices Modeling Project

Insights as Seattle area office workers return

2022

Seattle Transportation

Issue

Telework surged during the COVID-19 pandemic due to public health measures. Although not every employment sector could have people work from home, many did during this time. As a result of these adjustments, transit ridership decreased, and peak-period travel reduced slightly on various roadways. As employers reopen offices for staff, there is uncertainty about what the new normal will look like for the transportation system and for transit use with many embracing telework and reexamining their commute options.

Spark

Transportation modelling is a valuable tool for determining how roadways and transit service could be affected by anticipated travel demand. Using trip-reporting data collected by the Puget Sound Regional Council prior to the pandemic, travel forecasts provide a range of possibilities. 

Overview

Scenario modelling could provide insight for what the new normal would look like in the Seattle area as office workers return. University of Washington project researchers used regional commute trip data collected prior to the pandemic to provide a better glimpse of what to expect on major network routes and transit lines. Additionally, bus rider survey results from King County Metro and Community Transit from 2021 and 2022 will help adjust those forecasts. Findings are shared with transit providers to compare with their estimates as travel preferences and commute demands may change.

Innovation

The pandemic disrupted old commute norms and transportation modeling needed to adjust to the evolving realities for more accurate travel demand insights. This project developed a procedure to use the model to forecast system and transit use. Additionally, this may be used for construction projects to anticipate new trips and plan for potential mitigation needs.

Materials

Results and scenarios are published on the study website. 

Impact

  • Transit agencies will be able to use this information to help guide decisions for service levels as commuters return to the office and embrace the hybrid work environment.  
  • Transportation agencies have a new tool to help understand the effects of travel changes due to hybrid work and new commute habits.
