London Public Transport Isochrone Map

This interactive map calculates scheduled public transport travel times across London directly in the browser. It samples journeys across weekday, weekend, evening, and night profiles and can display best, median, average, worst, and variability results. Origins can be selected by transport stop or active postcode, with approximate initial and final walking included.

Routing uses precompiled TfL and National Rail timetable data. The deployed application is static and does not call third-party routing APIs at runtime.
