TriMet

The Tri-County Metropolitan Transportation District of Oregon (TriMet) is a public agency that operates mass transit in a region that spans most of the Portland metropolitan area in the U.S. state of Oregon. Created in 1969 by the Oregon legislature, the district replaced five private bus companies that operated in the three counties: Multnomah, Washington, and Clackamas. TriMet started operating a light rail system, MAX, in 1986, which has since been expanded to five lines that now cover 59.7 miles (96.1 km), as well as the WES Commuter Rail line in 2009. It also provides the operators and maintenance personnel for the city of Portland-owned Portland Streetcar system. In 2022, the system had a ridership of 53,889,500, or about 196,100 per weekday as of the third quarter of 2023.

In addition to rail lines, TriMet provides the region's bus system, as well as LIFT paratransit service. There are 688 buses in TriMet's fleet that operate on 85 lines. In 2018, the entire system averaged 310,000 rides per weekday and operates buses and trains between the hours of approximately 5 a.m. and 2 a.m. TriMet's annual budget for FY 2018 is $525.8 million, with 30% of resources coming from a district-wide payroll tax and 10% from fares. The district is overseen by a seven-person board of directors appointed by the state's governor. As of 2022, the agency has around 3,428 employees.
