Measures showing Tri-Cities US 395 and SR 240 performance
Indicators
This dashboard shows three multimodal performance indicators for US 395 and SR 240 in the Tri-Cities region: annual general purpose lane (GP) person miles traveled, annual GP vehicle delay, and percentage of park and ride spaces occupied.
For details on methodology to calculate person miles traveled and vehicle delay, refer to WSDOT's Handbook for Corridor Capacity Evaluation (PDF 5.9 MB).

Multi-year trends
In 2021, annual GP person miles traveled and vehicle delay increased from 2020, due to the recovery of traffic volume. In 2020, the statewide response to the COVID-19 mitigation policy, such as an increase in telework and no large gatherings of events, resulted in reduced traffic. This significantly reduced the GP person miles traveled and vehicle delay compared to previous years.
From 2017 to 2019, in the Tri-Cities area, the US 395 corridor experienced a significant increase in the person miles traveled from 73 million to 105 million while SR 240 corridor was down from 44 to 39 million. But in 2020, both US 395 (97 million) and SR 240 (35 million) corridors' person miles traveled decreased, due to the fewer traffic caused by COVID-19 outbreak.
Between 2017 and 2019, annual vehicle hours of delay increased substantially on US 395 (from 88,000 hours to 196,000 hours) and SR 240 (from 45,000 hours to 84,000 hours). In 2020, both US 395 and SR 240 saw reductions in vehicle hours of delay by 122,000 hours and 42,000 hours, respectively, compared to 2019.
Annual highlights
