Public Transport queries

Query public transport connections for set of trip requests (from origin to a destination at given departure time).

This python library uses OpenTripPlanner to query single or multiple trips (origin, destination, departure time) for their detailed PT routes.

It was succesfully applied to query 3 million trips from 6 different cities in one of our research projects.
