Open Source Public Transport Accessibility Modelling

The RGS-IBG annual conference has been on this week, and I presented as part of a series of geocomputation sessions arranged in advance of the 21st anniversary Geocomputation conference in Leeds next year. The topic was current CASA research from the RESOLUTION project, looking at developing fast and consistent methods of measuring public transport accessibility between different cities.

For this task I have been testing the OpenTripPlanner software with encouraging results. PDF of the slides are here.

The data used for the London analysis comes from the Traveline public transport timetable data. The image below shows an example accessibility measure of jobs accessible within 1 hour’s travel time leaving at 8am.
