Can you talk transit?

Photo:  CBDEvery profession has its own insider lingo. Waitresses order up “Adam and Eve on a raft.” Journalists “break” a story with an attention-grabbing “head” and “lede.” And, cops put out an “APB” for a “perp” with a particular “MO.”

The transit industry is no different. At King County Metro Transit there are a variety of terms used as shorthand that describe how the system operates. Here are just a few:

Access – Metro’s van-operated service for people with disabilities is called Access. It has no fixed routes or schedule, and can only operate on the same days, same areas and same time as Metro’s regular fixed-route service. Access passengers must qualify for service under the Americans with Disabilities Act (ADA) paratransit program before they can request rides.

APC – The Automatic Passenger Counters (APC) used by Metro are mats placed on the stairwell steps on 10 percent of the buses. The mats count the number of passengers getting on and off the bus. While the buses may move around and get assigned to various routes/runs, the APC mats are a permanent installation on the bus.

Base – A transit base, which sometimes is called a bus barn, is a facility that operates and maintains the buses. Metro has seven bus bases: three in downtown Seattle; two in Bellevue; and one each in Shoreline and Tukwila. Buses and transit operators are assigned to and work from a specific base.

Boarding/ride/trip – A single passenger getting on a transit vehicle is referred to as a “boarding.” A single segment ridden on a single transit vehicle is a “ride.” The passenger’s total journey between first and last boarding is the “trip.” A single trip may include multiple boardings and multiple rides.

The Book – The procedures and policy manual handed out to all drivers, and updated several times a year, is simply known as The Book. It also includes turn-by-turn descriptions of all Metro routes.

Bus – A rubber-tired transportation vehicle for multiple passengers is the technical definition of a bus; also called a coach.

CBD – Seattle’s Central Business District (CBD) is roughly from Elliott Bay to 9th Avenue between Broad Street on the north and Jackson Street on the south. It is Metro’s busiest service area.

Comfort station – A specific restroom along a route that can be used by bus drivers is called a comfort station.

Contraflow – A bus lane where buses operate in the opposite direction from other traffic on what would otherwise be a one-way street is called a contraflow lane. An example in downtown Seattle is Ninth Avenue between Olive Way and Stewart Street.

DART – Metro's Dial-a-Ride Transit (DART) offers variable routing in some areas within King County. It uses vans that can go off regular routes to pick up and drop off passengers within a defined service area. It operates on a fixed schedule, but one that has more flexibility than regular routes.

Deadhead – The time spent driving to and from the base or between terminals on different routes is called deadheading.

E3 Busway – In the mid 1990s, the state built a transit-only roadway along Fifth Avenue South between Royal Brougham Way and Spokane Street to help move buses more quickly between downtown Seattle and Interstate 5. There were multiple alternatives and options on the drawing board, and the one finally selected was Alternative E, Option 3. The “E3” designation stuck. Currently, the busway is being retrofitted for use by both buses and light rail. Sometimes you may hear it called the “SODO Busway.”

First liner – A “first line supervisor” is an experienced transit employee who is the first to respond to problems out in the field. This can range from helping a trolley driver reattach poles to the overhead wire; assisting passengers at bus stops; or securing the scene of an accident until police arrive. Many first liners make their rounds in white Metro vans, and are assigned to one of 20 separate geographical districts in King County. First liners also staff the communications center, the base operations desk, and run the training program for new drivers.

FlexPass/U-PASS - The FlexPass is an annual transportation pass that offers access to bus, commuter rail, vanpool, vanshare, and emergency ride home services. It is purchased by employers for their employees, and services are tailored to employee needs at that particular work site. The price of a FlexPass program depends on the actual level of use of transit and other services among all employees at a participating worksite. That is why not all FlexPass programs are the same. At the University of Washington, this program is called the U-PASS.

Frequency – Frequency is usually expressed as the number of trips per hour on a single bus route. For example, the Route 7 has a six-trips-per-hour frequency on weekdays.

Headway – The amount of time between consecutive trips on the same route in the same direction of travel is known as headway. For example, the Route 7 has a 10-minute headway on weekdays.

Photo: Hybrid busHybrids – The newest buses in Metro’s fleet are hybrid coaches operating on both diesel and electric (battery) propulsion. There are 213 of these 60-foot clean-air coaches in the system.

Inbound/outbound – In most cases on routes traveling through Seattle, the buses are considered inbound when they are headed toward the city and outbound as they travel away from Seattle. There are some exceptions.

Layover – Both bus drivers and buses need to take a break, also known as a layover. The driver needs the layover to take a rest break, use the restroom, or have a meal. The buses need the break to provide a time cushion in the schedule. Most layovers occur at the end of a route, so you may see buses parked on the street or at a transit center for anywhere from 10 to 30 minutes at various times throughout the day.

Operator – You say “bus driver.” We say “transit operator.”

Park-and-ride - A park-and-ride lot is property provided for transit customers to be used as a hub where passengers can park their cars or bicycles and board a bus route, carpool or vanpool. Metro currently operates 123 park-and-rides with more than 22,000 parking spaces. Park-and-rides make transit use and ridesharing more convenient, and reduces the number of single-occupancy vehicles on the road and the distances they travel.

Passenger load – The number of passengers divided by the number of seats on the bus is called the passenger load. It is expressed as a ratio and is measured at different points along the route. Transit planners are interested in where the maximum loads occur on the route. A passenger load above 1.0 indicates that sometime in the bus trip at least one passenger was standing.

Peak service – The peak occurs when Metro has the most buses in service. This occurs twice a day on weekdays, from 6-9 a.m. and from 3-7 p.m. At the height of the peak, Metro has about 1,150 buses on the road.

Photo:  Bus on the highway Revenue/platform hours – The number of hours a bus is operating scheduled trips is referred to as revenue hours. This does not include deadhead time or layovers. Platform hours are the total number a bus is on the road during the day.

Ride Free Area (RFA) – Metro’s Ride Free Area (originally known as the “Magic Carpet Zone”) extends from the north at Battery Street to South Jackson Street on the south, and east-to-west from Sixth Avenue to the waterfront. It applies to almost all routes traveling through downtown between 6 a.m. and 7 p.m. It was introduced in 1973 as a way to encourage transit use and reduce congestion downtown. It also keeps buses moving more quickly through the downtown area since passengers can hop on and off via all doors. The city of Seattle shares the operating cost with Metro.

Route/run – A route refers to a trip that follows a specific path. A run is one of those trips that a bus takes. For example the Route 196 travels between downtown Seattle and the South Federal Way Park-and-Ride 18 times a day – so there are 18 runs on Route 196.

Shake-up/Service Change – Three times a year – in February, June and September – Metro updates its routes to improve service and keep up with the changing needs of transit passengers. This is also a time when there is a reallocation of buses and some of the transit employees. Eligible employees can select their location and work hours by seniority within their job class. Some bus drivers like to pick the same work assignment every shake-up, while others like variety and move from route to route.

Photo: Special service busSpecial service – Metro operates supplemental bus service to special events open to the general public, like Seahawks football games, the Seattle Home Show, and Seafair. The extra service is paid for by the organization hosting the event, and Metro works with those organizations to determine the specific fare for that particular special service.

Terminal – The end of the bus route where all passengers have to disembark.

Trolley – Metro is one of the few major transit agencies in the nation to have an extensive system of electric buses powered by overhead wiring. Overhead wiring exists in downtown Seattle; the University District; First, Beacon, and Capitol hills; Queen Anne; Wallingford; Ballard; and the Rainier Valley.

ULSD – Metro uses ultra-low sulfur diesel fuel (ULSD) in all of its diesel and hybrid buses.

VanPool/VanShare – When groups of people carpool together in a publicly owned passenger van, the program is called vanpooling. Metro offers one of the oldest and largest vanpool programs in the nation. It provides the van, maintenance, insurance, fuel, tires and training. Metro also offers the VanShare program to help those who need to make a connection to or from bus service.
 
Zone – A zone is more commonly referred to as a bus stop. It is an on-street location where transit vehicles stop to pick-up and discharge passengers. It has a sign and basic service information, sometimes also a shelter with benches.
