Introduction

Ruter, as the Public Transport Authority (PTA) of Greater Oslo, offers a complete API for all aspects of realtime communication between vehicles and the Ruter backoffice. Based on position, automated passenger counting (APC) and other sensor data from vehicles, Ruter’s backend platform generates aggregated services both for consumption in the vehicle, on stop displays, as well as Ruter’s own operation control and data analysis.

The API is based on a set of MQTT topics being standardised by the European organization ITxPT to facilitate easier and more transparent integration between services from vehicle manufacturers, system providers, Public Transport Operators (PTOs) and PTAs.
