Layover#

a.k.a. “Terminal”

A designated location for Transit Units or Vehicles to idle in-between scheduled trips, commonly where operators break, change shifts, and where supervisors are stationed.

Where “terminal” is a more universal term across public transport Modes, “layover” is more commonly used for bus services.

Layover Time#

a.k.a. “Terminal Time”

The duration a Transit Unit spends at a terminal in-between consecutive scheduled trips.

This is an important factor to consider in scheduling, to ensure drivers and operators have a sufficient break in-between trips.

Metrics:

  • Time (in minutes)

  • Percentage (%) of runtime or cycle time.

Line#

Branch Line
Feeder Line
Intercity Line

A type of regional public transportation service that connects two cities or metropolitan areas. Common examples are commuter rail and commuter bus services.

These are the fundamental services planned for regional level coverage.

Loop / Circulator
Radial Line

A public transport route that links a central location to a satellite location, within a city or metropolitan area.

Trunk Line

Load Factor#

a.k.a. “α (alpha)”

The capacity utilisation rate of a public transport service.

It is used to measure the effectiveness of a public transport service, whether the supply (seats provided) is being utilised and thus is worth the cost of investment.

Metrics:

  • Percentage (%)

  • Ratio

The Load Factor is calculated by…

\[ \frac{Σ passenger km travelled}{Σ seat km travelled} \]
