OTP Finds a way

OpenTripPlanner is a mature, open-source engine for multimodal journey planning across public transport, walking, cycling, micromobility, and driving/park and ride.

It supports datasources on multiple different format (NeTEx, GTFS), consumes hundreds of realtime updates per second to timetable data while delivering fast response times.

With all these capabilities it is important to map real world as accurate as possible.

How do you manage time-traveling trains, ghost buses, levitating trains, and how long is a staircase?

Inconsistent data, outliers and quirky rules go head to head with configuration and algorithms in a battle to answer the questions, what is the best journey from A to B.
