GTFS Realtime - Trip Updates - Metro Bus
GTFS Realtime Trip Update feed for Metro Bus provides real-time arrival, departure and delay information of a trip for metro buses in Melbourne, Victoria. The feed doesn’t include train replacement buses, service deviations (skipping stops or changing routes), platform information or cancellations. Note: This API endpoint has a rate limit of 20-27 calls per minute (depending on the data size) and caching time of 30 seconds.
