Aubin (Junction / Aubin MaaS Limited)

Aubin is a multi-modal, highly customisable journey planner and travel companion designed for neurodivergent travellers in Great Britain. It uses OpenTripPlanner as the journey planner backend, with features catering for usage in Great Britain.

Aubin allows travellers to easily plan journeys such as taking bikes on board, park and ride, stop-off locations, and adjusting fine-grained preferences such as relative weights for different travel modes, walking speed, and transfer times.

While developing this product, I contributed a lot into OpenTripPlanner, including performance enhancements and better adherence to standards, and also contributed a proposal to GTFS-RT standard such that we can model the rail operations more accurately. It is now the largest production deployment of OpenTripPlanner in terms of geographical area.

Under the hood, I also worked on transforming and tidying the source data into GTFS standards so that they can be presented nicely by an OpenTripPlanner client without custom logic.

Due to high resource usage, this website is currently taken private while a rewrite is in progress. The source code is available on GitHub for anyone to deploy an instance.
