Who we are

Carris Metropolitana is the public transit backbone of the Lisbon Metropolitan Area, and we’re on a mission to make getting around simpler, faster, and more reliable for everyone. We believe in the power of collaboration and open data to improve transit experiences. This is your one-stop shop for everything you need to know about integrating with our transit ecosystem, whether you’re building a real-time transit tracker, a community-powered app, or just geeking out over GTFS datasets.

Our GTFS implementation

Learn about our implementation of GTFS, both Scheduled and Realtime data. Explore the TML extension, designed to augment the information provided to the public about the transit networks.

🛠️

JSON API

Build interactive live experiences using our REST API. We provide vehicle positions, arrival estimates and scheduled data in JSON for our whole network. From fetching upcoming trips to querying live wait times at ticketing locations, our API has you covered.

🌍

Datasets

We share datasets in our GitHub repository that are useful to us, and perhaps to you too. They are updated regularly and we're always expanding the collection.

🐝

Open Source projects

We are committed to open-source principles, and our public repositories include projects such as our website, mobile apps, API implementations, and experimental tools. These projects are available for you to explore, use, or contribute to.

This platform reflects our commitment to transparency, innovation, and collaboration in public transit. Whether you’re developing a new app, conducting research, or simply exploring transit data, we’re here to support your efforts.
