Transit Definitions

Here are some commonly used transit terms used in VTA's data and their definitions:

Block: A collection of trips assigned to a vehicle for a day.

Direction: One of four possible directions of travel –Northbound, Southbound, Eastbound or Westbound-- on a route.

Stop ID: The unique number that identifies each bus and Light rail stop.

Pattern: A unique travel path through the street network to visit selected stops for one trip.

Route: A collection of ordered stops presented publicly as a "line" with a name (such as "22 – Palo Alto Transit Center") and represented internally as an integer.

Timepoint: One of several stops on each route that serves as a benchmark for whether a trip is running on time.  Timepoints are the only stops that appear on our printed schedules.

Trip: An iteration of a vehicle traveling along a given pattern. (Example: Line 22 makes a trip from Eastridge Transit Center to the Palo Alto Transit Center. Palo Alto transit Center to Eastridge Transit Center would be its next trip.)
Headsign Route description that appears on the display on the front of the bus.  (Example:  22 – Eastridge)
