🗳️ Currently Voting
Clarify use of agency_fare_url #524
This PR extends the definition of agency_fare_url to also include URL pages with fare information instead of just pages that allow purchasing tickets.
Specify the behaviour of TripUpdate.schedule_relationship = ADDED, and un-deprecate REPLACEMENT #504
This PR specifies the behavior of ADDED, and un-deprecate REPLACEMENT, based on the implementation of OpenTripPlanner which specifies the whole journey to be added or replaced. Additional fields, such as headsigns, and pickup / drop-off types, are introduced as required to support the full specification of completely new trips.

The GTFS Realtime Alert active_period field is ambiguous, as it could mean either the alert's display period or the disruption's duration. A proposal suggests adding communication_period for the alert's display and impact_period for the disruption timeframe to clarify its use.
Add a provision for event-based trips (to support modeling of trips departing "x minutes following an event") #526
