Description
As of #2, gtfs-via-postgres
supports all frequencies.txt
rows with exact_times=1
, but not those with exact_times=0
.
Frequencies.txt represents trips that operate on regular headways (time between trips). This file can be used to represent two different types of service.
- Frequency-based service (
exact_times=0
) in which service does not follow a fixed schedule throughout the day. Instead, operators attempt to strictly maintain predetermined headways for trips.- A compressed representation of schedule-based service (
exact_times=1
) that has the exact same headway for trips over specified time period(s). In schedule-based service operators try to strictly adhere to a schedule.
It is unclear how to model frequency-based services in the existing arrivals_departures
& connections
views, which are currently designed to handle schedule-based services only.
The minimal-effort option would be to expose exact_times
in arrivals_departures
& connections
, but consumers would have to take care to either a) filter exact_times=0
rows out, or b) make sure they handle both cases correctly.
