set_servicepattern: Calculate servicepattern ids for a gtfs feed

In r-transit/tidytransit: Read, Validate, Analyze, and Map GTFS Feeds

Calculate servicepattern ids for a gtfs feed

Description

Each trip has a defined number of dates it runs on. This set of dates is called a service pattern in tidytransit. Trips with the same servicepattern id run on the same dates. In general, service_id can work this way but it is not enforced by the GTFS standard.

Usage

set_servicepattern(
  gtfs_obj,
  id_prefix = "s_",
  hash_algo = "md5",
  hash_length = 7
)

Arguments

gtfs_obj	gtfs feed (tidygtfs object)
id_prefix	all servicepattern id will start with this string
hash_algo	hashing algorithm used by digest
hash_length	length the hash should be cut to with substr(). Use -1 if the full hash should be used

Value

modified gtfs_obj with added servicepattern list and a table linking trips and pattern (trip_servicepatterns)
