TriMet, more formally known as the Tri-County Metropolitan Transportation District of Oregon, 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 named MAX in 1986, and opened new lines in 1998 (Westside), 2001 (Airport), 2004 (Interstate Ave.), and 2009 (Clackamas), as well as a commuter rail line in 2009. It also operates the City of Portland-owned Portland Streetcar system.
In addition to rail lines, TriMet provides the region's bus system, as well as LIFT paratransit service. There are 610 buses in TriMet's fleet that operate on 79 lines. In Fiscal Year 2013, the entire system averaged almost 316,700 rides per weekday and operates buses and trains between the hours of approximately 5 a.m. and 2 a.m. with no "night owl" service. TriMet's annual budget for FY2014 is $489 million, with over half of revenues coming from a district-wide payroll tax. The district is overseen by a seven-person board of governors appointed by the state's governor. In 2014, the agency has around 2,500 employees.

TriMet is "a municipal corporation of the State of Oregon", with powers to tax, issue bonds, and enact police ordinances and is governed by a seven-member board of directors appointed by the Governor of Oregon. It has its own boundary, which currently encompasses an area of about 533 square miles (1,380 km2). The TriMet district serves portions of the counties of Multnomah, Washington, and Clackamas; it extends from Troutdale to Forest Grove east to west, and from Sauvie Island to Oregon City and Estacada north to south.
For more than 30 years the agency called itself Tri-Met, but it formally dropped the hyphen from its name in 2002, as part of a new corporate identity strategy involving a redesigned logo and new color scheme for its vehicles and other media.
TriMet was formed in 1969 after disputes between the Portland city council and Rose City Transit Company, the private company that previously operated the bus system serving the city (but not its suburbs). The new public agency was created by an ordinance of the Portland city council, under provisions of a law enacted by the 1969 Oregon Legislature, and took over all of Rose City Transit's service and fleet effective December 1, 1969. Bus service in the suburban portions of the metropolitan area was operated by four smaller private companies which had a common union and were collectively known as the "Blue Bus" lines: Portland Stages, Tualatin Valley Buses, Intercity Buses and Estacada-Molalla Stages. These were taken over by TriMet on September 6, 1970. Eighty-eight buses owned by the four suburban companies were transferred to TriMet, but many were found to be in poor condition and the TriMet board soon took action to replace them with new buses.
In Fiscal Year 2015, TriMet operated a total of 610 buses on 79 lines, 127 MAX light rail cars on four lines, and 253 LIFT paratransit vehicles. MAX and 12 of the bus lines are marketed as "Frequent Service" lines, scheduled to operate at headways of 17 minutes or better for most of the service day, seven days a week.

TriMet also links to various local shuttle services operated by the following: Ride Connection, which serves Banks, Gaston, King City and North Plains; the Swan Island Transportation Management Association; the Tualatin Transportation Management Association; Intel; Nike; and Oregon Health & Science University, including the Portland Aerial Tram.
Long-range transportation planning for the metropolitan area is provided by Metro, an elected regional government. Metro also has statutory authority to take over the day-to-day operations of TriMet, but has never exercised that power, as past studies of such a merger have found it to be problematic.
TriMet runs the MAX Light Rail (short for Metropolitan Area Express) system, and contracts with Portland and Western Railroad to operate the WES Commuter Rail line (short for Westside Express Service). Fares on MAX (as well as WES) are the same as TriMet bus fares, and fare collection uses a proof-of-payment system (or honor system) with ticket vending machines at each station. Fare inspectors patrol the system randomly. Incidents of violence on the system have led to calls for more security, and some have argued that more thorough checking of fares would improve riders' overall feeling of safety.
The TransitTracker system uses satellite tracking on buses and sensors in the MAX tracks to predict arrival times at stops and stations. Additionally, TriMet is partnering with Google Maps to install Bluetooth low energy beacons on MAX platforms, allowing nearby Android device users to directly receive schedule and alert information.
TriMet trains operate using reporting mark TMTC.
TriMet's rail lines include:
- Light rail
- Blue Line: Hillsboro – Beaverton – City Center – Gresham
- Green Line: Clackamas – City Center – Portland State University
- Red Line: Portland International Airport – City Center – Beaverton
- Yellow Line: Expo Center – City Center – Portland State University
- Orange Line (under construction): Union Station – City Center – Milwaukie
- Commuter rail
From 1991 until 2014, TriMet also operated the Portland Vintage Trolley service, which ran on a portion of the MAX system on most weekends. It was reduced to only seven dates per year in 2011 and was discontinued entirely in July 2014.

As of February 2014, TriMet was operating 79 bus routes. Of these, 12 were designated as "Frequent Service Lines", which the agency defines as having a headway of 17 minutes or less during weekday rush hours. Each route is identified by both a number and a name. The numbers are mostly in the range 1–99, but there are currently four routes with three-digit numbers. From 1969 until 1973, TriMet bus routes were named but not numbered, a practice inherited from Rose City Transit and the "Blue Bus" lines, but route numbers were assigned to all routes in August 1973.
The bus system includes 17 transit centers, facilities served by multiple bus routes, and 11 of these are at MAX stations. See List of TriMet transit centers. TriMet buses began carrying bicycles on the front in 1992, on a trial basis on eight routes; the experiment was judged a success and within three years the entire bus fleet had been fitted with bike racks. Each rack can hold two bikes.
Since September 2012, TriMet has used a "flat" fare system, with a single price (for each category of rider: adult, youth, senior or disabled) regardless of the length of the trip, rather than a distance-based fare system. However, the single-fare tickets permit unlimited transfers to other routes within a two-hour period. Previously, the TriMet district was divided into three fare zones, with fares based on the number of zones in which a passenger traveled. Zone 1 consisted of downtown Portland and extending about one to two miles (3 km) out. Zone 2 was a ring around Zone 1 out two to three more miles. Zone 3 wrapped around Zone 2 and consisted of the rest of the system within the suburbs of Portland. Within Zone 1 was Fareless Square, an area in and around downtown within which all rides were free. The zone was created in 1975 and expanded in 2001, but in 2010 it became applicable to light-rail and streetcar service only, no longer to bus service, and renamed the "Free Rail Zone", and in September 2012 it was discontinued entirely.
In September 2013, TriMet released a mobile ticketing app, allowing riders to purchase and use tickets for buses, light rail, and commuter rail on their smartphones. The app, called TriMet Tickets, was developed by Portland startup GlobeSherpa at no cost to TriMet. Instead, GlobeSherpa will take a commission on every ticket sale through the app.
An e-fare system is being developed by TriMet, the City of Portland, and C-TRAN that will enable riders to pay with a fare card, near field communication–equipped smartphone, or credit card, using card readers on buses and train platforms. The system is expected to cost $30 million to develop, and will be implemented in phases: employee testing in 2015 after the opening of the MAX Orange Line, public beta testing in 2016, and full implementation in 2017. TriMet listed possible names for the system as 1Pass, Indigo, Umbrella, Via, and Lynx.
TriMet's fleet includes 603 buses, in lengths of either 40 or 30 feet (12 or 9 meters). Currently, about three-fourths of TriMet's buses are low-floor vehicles. The agency's fleet of paratransit vehicles included 253 minibuses and 15 vans as of February 2014.
TriMet does not currently operate any 60-foot (18 m) articulated buses. In 1982, the agency introduced 87 such buses, manufactured by Crown-Ikarus, a now-defunct partnership between Ikarus, of Hungary, and Crown Coach, of California, but experienced numerous problems with them, and has not purchased any more articulated buses. The last such buses were retired in 1999. However, over the intervening years the agency has introduced and expanded its MAX light rail system, which also uses higher-capacity, articulated vehicles. In 1997, the TriMet board decided that all buses purchased in the future should be low-floor type and equipped with air-conditioning. The decision was for a gradual phase-out of high-floor, non-air-conditioned buses as they reach the ends of their normal lifespan (about 18–20 years) and TriMet anticipates that by 2017 all buses will have low floors without steps.
Two hybrid electric buses entered service in 2002, but in 2008 TriMet stated that the buses had not performed sufficiently better than its newest diesel buses to justify the estimated 50-percent-higher purchase cost, and that consequently the agency had no plans to purchase additional hybrid buses at that time. The two 2001-built hybrid buses were retired in 2012. However, with hybrid technology having improved since that earlier purchase, TriMet acquired four new hybrid buses in 2012 and placed them into service in January 2013 on line 72, a long, mostly level north–south route.
Since October 30, 2006, all TriMet buses and paratransit minibuses have been fueled by a B5 biodiesel blend. Plans to increase to a B10 or higher mix were later put on hold as a result of cost increases and problems experienced in a trial use of B10 blend in about one-quarter of the fleet.
In 2008 TriMet ordered 40 New Flyer D40LFR buses, which model features restyled ends, and these entered service in 2009. These buses offer better fuel efficiency and quieter operation than previous New Flyer buses while maintaining high parts compatibility. The restyled look replaces the square-shaped headlights and front windows with round headlights and a more rounded windshield. In fall 2012, 55 new buses built by Gillig began to enter service. In 2013, another 70 Gillig buses were purchased, the first six of which entered service in late July. Sixty more Gillig buses gradually entered service over the summer of 2014, and another 30 of the same type followed soon afterward, beginning to enter service in October 2014. In early 2015 TriMet received its first new 30-foot buses in more than 20 years. These 22 Gillig buses are similar to the rest of TriMet's new buses, but their shorter length allows them to serve routes with tighter turns and difficult terrain.
TriMet's buses operate out of three garages: Powell Garage to the east, Merlo Garage on the west side, and the Center Street Garage in inner Southeast Portland.

Items in the following timeline lacking individual citations are taken mostly from TriMet's Rider Insider newsletter, November/December 2004 issue:
- 1969 Tri-Met takes over for the nearly bankrupt Rose City Transit Company. The system has 175 buses and a daily ridership of about 65,000.
- 1970 Tri-Met takes over the "Blue Bus" companies, the four companies which had been providing bus service to and within Portland's suburbs, adding another 88 buses to the agency's fleet.
- 1973 Route numbers (or Line numbers) are adopted for the first time; previously, routes had been designated only by names.
- 1974 The first shelters at bus stops are installed.
- 1975 The "Fareless Square" is created in downtown Portland, with the goal of reducing short automobile trips within the city core and attracting more riders. Fares outside the Square are 35 cents. The zone-based fare system was discontinued at that time, but was reinstated less than four years later and remained in use until 2012.
- 1977/78 The 22-block Portland Transit Mall opens on downtown's Fifth and Sixth Avenues. The mall includes bus-only lanes and provides a hub to make it easier for riders to make connections.
- 1978 After 3½ years using a "flat" fare system, a zonal fare structure is reinstated, with three fare zones.
- 1981 24-hour recorded schedule information becomes available over the phone.
- 1982 Tri-Met introduces articulated buses for the first time. The Crown-Ikarus buses prove to be sufficiently trouble-plagued that the agency later sues the manufacturer to recover expenses tied to excessive repairs; a settlement was reached in 1987.
- 1982 In September, Tri-Met introduces a proof-of-payment (or "self-service") fare system for all service, but discontinues it in June 1984, due to fare evasion, high equipment repair costs and other problems.
- 1986 As part of a package of budget cuts, Tri-Met discontinues its all-night "Owl" service, making Portland the second largest U.S. city without all-night transit service. Seven regular (daytime) bus routes also were eliminated.
- 1986 The 15-mile (24 km) long MAX light rail line between Portland and Gresham opens. It reintroduces rail transit service to the Portland area, missing since the 1950s.
- 1989 Tri-Met is named the best large transit system in North America by the American Public Transit Association.
- 1992 The first bike racks are installed on the fronts of some Tri-Met buses, as part of a one-year trial project.
- 1995 Tri-Met's website goes online, hosted by local ISP Teleport (which eventually becomes acquired by OneMain.com, later to become part of Earthlink). At the time when Internet access was less ubiquitous, Tri-Met also offered a dial-up information service through Teleport using a Unix shell and Lynx.
- 1996 Tri-Met begins to equip its bus fleet with vehicle tracking system equipment, to enable monitoring of buses in service, using GPS technology.
- 1997 The first low-floor buses and light-rail cars go into service.
- 1998 Westside MAX (now known as the Blue Line between Portland and Hillsboro) opens. Tri-Met also establishes bus lines that come every 15 minutes or sooner everyday, lessening the need to consult a schedule when using them.
- 1999 Satellite-assisted bus arrival time displays (later to be named Transit Tracker) are installed at select major bus stops in North Portland and downtown.
- 2001 Fareless Square is expanded to a small portion of Northeast Portland between Lloyd Center and the Steel Bridge. Airport MAX (the Red Line) begins service on September 10 after a public/private partnership, prompted by a proposal from Bechtel Corporation, enables its construction years ahead of TriMet's plans for the use of public funds. Bechtel received exclusive development rights to 120 acres (486,000 m²) near the entrance to Portland International Airport. The original MAX line began to be referred to as the MAX Blue Line upon the opening of the Red Line. Bus sector symbols began to be phased out from maps and publications.
- 2002 With the September schedule change, Tri-Met launches a new corporate identity strategy. It is renamed TriMet (without a hyphen) and a new logo and blue, white and yellow livery are introduced. An improved automated phone service is introduced.
- 2004 Interstate MAX (the Yellow Line) opens along Interstate Avenue. The fleet has grown to 638 buses, 208 paratransit vehicles, and 105 trains with a daily ridership of over 300,000.
- 2005 TriMet introduces biodiesel fuel into its fleet, using a B5 blend (5 percent pure biodiesel, 95 percent petroleum diesel), initially on LIFT (paratransit) minibuses only. Use of B5 biodiesel was expanded to the entire bus fleet in late 2006.
- 2007 The Portland Mall, on 5th and 6th Avenues, is shut down for rebuilding and southward extension (to PSU), including adding a second light-rail alignment through downtown. The rebuilding, to take over 2 years, is part of the MAX Green Line project, but will also replace all infrastructure for buses on the already 29-year-old transit mall. Most bus routes serving downtown are detoured to other streets until 2009.
- 2009 The 14.7-mile (23.7 km) WES Commuter Rail opens on February 2. WES (Westside Express Service) provides service between Beaverton and Wilsonville with stations in Tigard and Tualatin in between.
- 2009 In May, the Portland Mall reopens for buses, and testing and training runs for the new Mall MAX tracks begin, for opening August 30.
- 2009 Due to the national recession's effect on the agency's finances, the board approves a series of service reductions, to take effect in September. The board votes on August 12 to discontinue Fareless Square for bus service beginning in January 2010, while retaining fare-free rides in the downtown area on MAX and the Portland Streetcar.
- 2009 On August 30, MAX service on the transit mall is introduced, with the shifting of the Yellow Line to the new alignment. September 12 brings the opening of the Green Line, also using the new transit-mall tracks, running from downtown (PSU) to Clackamas Town Center. It is TriMet's first light rail line serving Clackamas County.
- 2011 Construction starts on Tilikum Crossing, the first construction work on the MAX Orange Line from Portland to Milwaukie.
- 2012 TriMet purchases 55 new Gillig diesel buses to replace the aging fleet dating back to 1990. The last four of the new buses are hybrid-electrics estimated to be 20-50% more fuel-efficient and produce 95% fewer emissions; they replaced hybrid buses that were in service since 2002.
- 2013 TriMet purchases 70 new Gillig diesel buses to replace the aging fleet dating back to 1990.
- 2014 TriMet purchases 90 new Gillig diesel buses.

Criticism and controversies
An investigation by The Oregonian led to the revelation that some TriMet drivers work as many as 22 hours in a 24-hour period. There have also been 22 reported cases of drivers falling asleep at the wheel.
Failure rate of MAX ticket vending machines
An investigation by several local Portland news outlets found that several of the MAX Light Rail ticket machines have extremely high failure rates. Many riders have claimed that they have received a fare evasion citation after boarding the MAX train without a fare after they have attempted to pay for a ticket. The official statement from TriMet is to ride to the next MAX station, de-board the train and pay for a ticket there and wait for the next train. This response has been deemed unacceptable both by riders and bus/rail operators. TriMet has begun replacing all of its older machines with newer machines, and cites a 50% drop in complaints.
Sanctioned for illegal employee negotiations behavior
On January 3, 2013 TriMet was found by The Oregon Employment Relations Board to be in violation of ORS 243.672 by restricting the ATU 757 from attending contract negotiation hearings. In retaliation to the ATU filing a ULP earlier in 2010, TriMet implemented a wage freeze requiring all employees to pay their increases in healthcare premiums and changing insurance plans after the union contract expired without first discussing it with the union.
