S

scalable

Mobile computing system that grows and adjusts to an organization's changing needs.

schedule

Planned work, assigned to times, within a transit agency.

FX lets users create schedules for fixed route service.

PASS uses template schedules as master schedules for specific week days and live schedules for daily work planning.

OPS imports work schedules from FX, BlockBuster, or third-party applications. Operators are assigned to scheduled work manually or through bids.

schedule adherence

  1. How closely a vehicle is able to adhere to its scheduled itinerary times.
  2. Application of management methods and controls to maintain schedules to a defined tolerance.

    The aim is a high degree of schedule reliability.

schedule status

Status of a trip as indicated in the Stat column in Trip Administration in the Trapeze4 Workstation. For example, U (Unscheduled), CD (Cancel At Door), or NS (No Show). User-defined schedule status codes are created in Trapeze4 Workstation ancillary data (File > Ancillary Data > Para > Service > Schedule Status Codes).

schedule time

  1. In PASS, the time a trip is scheduled for pick-up or drop-off.
  2. In FX, the time a vehicle is scheduled to pass a node or timepoint.

schedule type

Classification for a schedule. Typically used in PASS for Live schedules (schedules for a specific date) and Template schedules (week day schedules used for subscription trips).

segment

Any part of a trip from a node or stop to another node or stop.

service

In Trapeze applications, a schedule generated for a specific purpose (typically, weekdays, Saturday, Sundays, or holidays).

Also called Days of Operations (used in UK).

See also service group.

service group

  1. Services that share a particular schedule. For each service created, a service group is automatically generated.

    Typically, transit agencies have four services: weekday, Saturday, Sunday, and holiday (or special events). For example, if a Sunday schedule is used for a January 1st holiday (New Year’s Day), then the New Year’s Day service would then be added to the Sunday service group.

    See also service.

  2. Trapeze application components defined when configuring the system.

service miles

Distance between vehicle pull-out and end-of-day pull-in.

Calculated from odometer readings.

See also revenue miles.

service request

Documented request for service for an asset. Typically used in EAM.

Set mode

Trapeze application feature used to specify parameters for the data to see in a screen or before performing a task. For example, sign-up period, line, service, division.

Primarily used in FX and the Trapeze4 Workstation.

Also called Context.

setting the tripper

Refers to flagging a vehicle as good for only short trips.

These vehicles are called short trippers.

shared workspace

Workspace defined by a system administrator and used by multiple system users.

Shared workspaces are standard because they're the same on everyone’s machines.

See also default workspace, private workspace, and workspace.

shop activity

  1. Activities necessary for operating a shop.
  2. Group of EAM portals used to manage many aspects of the various roles in the shop including supervisor, technician, production manager, and storekeeper.

short pattern

Trip that operates to an intermediate terminus rather than the regular outer route terminus.

This is often used to provide greater capacity to a specific route segment during peak traffic periods.

short turn

Trip that doesn't operate for the entire length of the route.

Some routes have high ridership in the inner core area and significantly less ridership in the outer route segments. Short turn trips provide more frequent service in areas of heavy demand.

See also turnback.

shuttle

Vehicle that travels back and forth over a particular route to carry operators to and from work assignments.

Typically, shuttles connect two transportation systems or centers.

Sign-Off Time

End time of an operator shift.

See also To time.

Sign-On Time

Time an operator reports to work.

See also From time.

sign-up period

Period of time that a particular set of schedules and operator assignments are in effect.

silent alarm

Message sent from a mobile unit to Dispatch after its covert switch is pressed.

The message is sent at the highest priority with infinite retries until acknowledged by Dispatch. The vehicle status is updated to covert emergency mode.

See also covert emergency mode.

single-insert scheduling

In PASS, a process that searches for scheduling solutions for a single booking.

See also batch scheduling.

site

A transit authority, property, or company.

Also called transit site, transit agency, or agency.

skill

Competencies and certifications associated with employee types, vehicle types, or other requirement types.

Qualified entities are able to meet the requirements of another entity. For example, an employee may have special training (be qualified) to drive an articulated bus (which has a requirement that employees must be specifically trained).

See also skill requirement.

skill requirement

Competency or certification that's either needed or preferred for someone or something to perform a task. For example, a vehicle type might need an operator to have a specific license to drive it, or a work type might prefer an employee with first-aid training to be assigned.

When mandatory skill requirements aren't met, the system gives an error. When optional skill requirements aren't met, a warning is given.

slack

  1. Extra amount of time given to an operator to travel between nodes that doesn't violate transit agency policy or the union agreement.
  2. Extra amount of time in a schedule for a vehicle to get to a stop, typically without passengers. For example, Vehicle 12 is due to arrive at point B from point A in 15 minutes, but the trip only takes 5 minutes. This results in 10 minutes of slack time.

smart card reader

Part of a fare payment system enabling customers to pay fares using smart cards.

Smart cards are credit card–sized payment cards that contain a microchip that stores information such as identification data and trip credits.

spacer

Route section that must be covered by another vehicle when the scheduled vehicle turns back.

See also spacer vehicle.

spacer vehicle

An unscheduled vehicle dispatched to perform service over a section of a route skipped by a scheduled vehicle when it's turned back because it's running late.

Late adherence violations should be waived for spacer vehicles because the service was already behind schedule.

See also spacer.

space type

Category definition for the area of space used by a passenger on a vehicle. For example, ambulatory or wheelchair. Typically used in PASS and defined in ancillary data.

special run

Run scheduled for a particular date and time that's not part of the main schedule.

Special runs are extra work created in OPS.

speed factor

Value used to modify the average speed under specific circumstances. Typically used in PASS.

Speed factors can be based on times, distances, runs, or locations.

split

Run consisting of two (or sometimes three) block pieces with a break (swing) between the pieces.

See also straight run and swing.

split end

Route that branches to serve more than one destination.

spread time

Period of time measured from the beginning of one shift to the end of the last shift for one operator on one operational day (for example, for split or double shifts). For example, if an operator works a four-hour piece starting at 8:00 AM and then another four-hour piece starting at 3 PM, the total spread time is 11 hours.

stage

Specific case state. For example, Violation Alert or Archived. Used in Service Infractions.

Cases are moved into new stages based on whether they meet certain policy criteria.

standby time

Time an operator spends at a garage waiting assignment of a run or piece of work.

Using standby time makes sure that a pool of operators is available to fill runs vacated by unscheduled absences.

standby work

Work assigned to employees so that they're able to take over other employees’ work as needed.

As standby employees come in for their shifts, they may be assigned to available work (based on demand).

See also extraboard.

start wait

Time an operator waits for transportation from the garage to a node (or vice versa) at the start of a shift.

Used in conjunction with travel time.

See also end wait.

State of Good Repair (SGR)

Condition rating for an asset determined by a rating system used in EAM.

stay in your seat transfer

stop pattern

Set of bus stops through which a specific trip type passes.

operator request

When a transit passenger pushes a button or pulls a cord to let the driver know they would like to exit the vehicle.

stop trip

Estimate of times from the headway sheets at bus stops using stop patterns.

straight run

Regularly scheduled daily assignment without unpaid breaks, except possibly meal times. Assigned trips are consecutive.

See also split.

subscription

Single booking created for multiple continuous trips. Typically used in PASS.

Subscription trips travel from the same origin to the same destination at fixed times and days. A subscription booking is comprised of three parts: a master record, template record, and live record.

Also called standing ride.

sudden absence

When an employee calls in to say that they can't make it on the day they're scheduled to work.

Sudden absences also include cases where employees only complete part of a shift. For example, due to illness.

See also absence.

supervisor

Person who works primarily on the street and supervises operators in specific areas and routes.

supplementary data

Agency-defined fields used to collect information in specific screens.

Supplementary data fields aren't defined by default, and must be added before they can be used.
Note: Don't confuse supplementary data with ancillary data. Supplementary data is made up of agency-defined fields. Ancillary data is made up of agency-defined values for existing fields. Ancillary data values often appear as options in dropdown lists when completing forms in Trapeze applications.

swing

Time between two pieces of work.

Swing time may be paid or unpaid, depending on agency policy.

switch

Control mechanism in Trapeze applications that defines aspects of how the system works.

Switches are typically defined by Trapeze personnel.

Depending on the Trapeze applications used by a transit agency, switches may be found in multiple locations. In the Trapeze6 Service Shell, switches are found under File > Trace Options. In Schedule Server, switches are found under View > Switches.
Note: Properties also have a significant impact on how Trapeze systems work.

synchronize

Replicating changes made in distributed or remote databases to a master (central) database to maintain data integrity.

system administrator

Person responsible for maintaining a multi-user computer system.

Typical duties include setting up user accounts including rights to perform functions, implementing procedures to prevent the spread of viruses, allocating mass storage space. For Trapeze applications, system administrator duties typically involve security permissions, properties, and ancillary data.

system map

Geographic representation of an area of land.

Geocoding the system map facilitates the use of many GPS-based features.

See also geocode.
