What is a Statewide Transportation System?

When we talk about transportation we’re talking about all forms of transportation: Cars and trucks, but also transit, biking, walking, rail and aviation, and marine transport.

The statewide system itself includes the facilities owned and operated by the Washington State Department of Transportation (WSDOT) and all of the state’s cities, towns, and counties, as well as facilities and services owned and operated by transit agencies, port districts, shippers, and independent operators. Increasingly it includes on-demand mobility services offered by transportation network companies like Lyft, Uber, and Waze.

Our Transportation System also includes the technology infrastructure that supports Transportation System Management and Operations (TSMO), and travel demand management (TDM) strategies, both of which help to make the existing system operate as efficiently as possible and reduce the need for more costly capacity projects.

These facilities accommodate over 7.5 million passenger vehicles, trucks and motorcycles.

They’re used by millions of people many times every day to get from “here” to “there” and back again by transit, pooling, walking, or biking, in addition to driving. Airlines, trucking companies, and maritime shipping lines depend on the statewide transportation system for reliable service from major ports of entry to our doorsteps. The statewide system supports local and state economies and connects Washington to the rest of the country and to the world.
