The <frequency/> Element

The <frequency/> element captures information about a trip that uses frequency-based scheduling. Frequency-based scheduling is where a trip doesn’t have specifically scheduled stop times, but instead just a headway specifying the frequency of service (ex. service every 10 minutes). The <frequency/> element can be a sub-element of a number of other elements:

Example

<frequency>
  <startTime>1289579400000</startTime>
  <endTime>1289602799000</endTime>
  <headway>600</headway>
</frequency>

Details

We include three fields:

  • startTime - the start time (unix timestamp) when the frequency block starts
  • endTime - the end time (unix timestamp) when the frequency block ends
  • headway - the frequency of service, in seconds
