Function to convert "HH:MM:SS" time strings to seconds.
Get a set of stops for a given set of service ids and route ids
Get all trip shapes for a given route and service
Returns all possible date/service_id combinations as a data frame
Convert NA values to empty strings ("")
Interpolate missing stop_times linearly
Uses shape_dist_traveled if available
Calculate shortest travel times from a stop to all reachable stops
Dataframe of route type id's and the names of the types (e.g. "Bus")

Cluster nearby stops within a group
Filter a gtfs feed so that it only contains trips running on a given date
Filter a gtfs feed so that it only contains trips that pass a given area
Returns TRUE if the given gtfs_obj contains the table. Used to check for
tidytransit's calculated tables in sublist (gtfs_obj$.)
Check if primary keys are unique within tables
Create a text listing the first max_agencies agencies of the feed
Filter a gtfs feed so that it only contains trips that pass the given stops
Convert empty strings ("") to NA values in all gtfs tables
Get all trip shapes for given trip ids
Convert stops and shapes to Simple Features
Filter a gtfs feed so that it only contains a given set of trips
Convert an object created by gtfsio::import_gtfs to a tidygtfs object
Example GTFS data
Filter a stop_times table for a given date and timespan.
Fallback function to convert strings like 5:02:11
10x slower than hhmmss_to_seconds(), empty strings are converted to NA
