Read GTFS-realtime alerts — read_gtfsrt

This function reads GTFS realtime alerts. Alerts are hierarchical: a single alert can have multiple applicability periods, multiple affected entities, and translations to multiple languages. This function flattens all of that to a tabular format, with one row for every combination of applicability, entity, and language. All rows from a single alert can be identified through a common id.

Usage

read_gtfsrt_alerts(filename)

Arguments

filename: filename to read. Can be uncompressed or compressed with gzip or bzip2. Can also be an http:// or https:// URL.
