Abstract

This study develops and demonstrates an open-source, reproducible workflow for measuring the temporal (service-time) accessibility of public transport for a specific age group (university students), and translates it into an operational, planner-oriented metric. Using OpenTripPlanner, GTFS and OpenStreetMap data, campus accessibility in six Polish cities is computed at one-minute resolution over a 16-hour window, as the cumulative minutes a campus is reachable within 30 minutes. Combined with census data, this yields the share of the student-aged population with access. The results consistently link rail infrastructure to higher, more stable accessibility and reveal marked central–peripheral disparities, offering planners a transparent diagnostic tool.
