Performance indicators for the SR 14 corridor in the Vancouver region

Indicators

This dashboard shows two multimodal performance indicators for State Route 14 in the Vancouver region:

  1. Annual general purpose (GP) lane person miles traveled
  2. Annual GP vehicle delay



Fiber optic communication lines, traffic data stations and traffic cameras have been installed along SR 14 and SR 503 in Clark County. This infrastructure helps travelers make informed decisions with more accurate real-time roadway information. Cost-effective ITS solutions like these, which allow the existing transportation system to operate as safely and efficiently as possible, are increasingly common along I-5, I-205 and other Southwest Washington highways.

For details on methodology to calculate person miles traveled and vehicle delay, refer to WSDOT's Handbook for Corridor Capacity Evaluation (PDF 5.9MB).

Multi-year trends

In 2022, annual person miles traveled and annual vehicle delay continued to increase compared to 2021, due to the ongoing recovery of traffic volume in the wake of COVID-19, but they were still lower than the pre-pandemic levels.

In 2020, the statewide response to COVID-19, such as an increase in telework and no large gatherings, resulted in significantly reduced traffic volumes and vehicle delay compared to previous years.

From 2018 to 2019, annual person miles did not change notably, while vehicle delay increased significantly.
