Next generation plug & play IT-systems for public transport
summary
Ruter runs public transport for 317 million passengers a year and builds a streaming back end around Apache Kafka and Kafka Streams to fuse GPS, APC sensors and MQTT messages into realtime passenger information, publishing compacted topics and using GraphQL for timetable data. The project implements the ITxPT standard, deploys driver terminals on Raspberry Pi/Android Things, and swaps AVM logic to the cloud so 400 new buses ship always-online capabilities. Contracted latency target is ~2 seconds but real-world delays can be minutes.
