Filon, the exploration – Cartographic & Spatiotemporal Transit Supervision

Engineered for the Keolis Tours public transit network, this interactive platform enables exploring and replaying comprehensive operational data. Bus runs, punctuality metrics, deadheading, mileage, and unexpected field events are mapped onto a dynamic Leaflet interface with a 13-month rolling history. Powered by a real-time architecture combining Azure, Symfony, API Platform, Redis, and Mercure, the system instantly benchmarks planned schedules against field reality. It equips dispatchers and executive leadership with unprecedented visibility to optimize public transit operations.
