A tool designed to strengthen the digital infrastructure of public transportation in Mexico and Latin America. With this open-access editor, agencies can generate and manage their GTFS data with full autonomy.
Ohtli is an open-access GTFS editor developed to help public transport agencies and mobility teams create, edit, and manage standardized transit data feeds with greater autonomy. It simplifies the process of generating GTFS datasets — including routes, stops, trips, schedules, and service calendars — through a more accessible workflow adapted to the realities of public transportation systems in Mexico and Latin America. By enabling agencies to structure and publish high-quality transit data, Ohtli supports integration with trip planners, mapping applications, and open mobility ecosystems. GTFS is the global open standard used to publish transit information for platforms such as Google Maps and other journey-planning tools.
