HDTP is an open public-transport data platform by Codeando México that standardizes and publishes GTFS mobility datasets for Mexican cities. The platform also provides a replicable methodology designed to lower the technical and operational barriers for municipalities to generate, maintain, and publish open transit data.

HDTP (Hub de Datos de Transporte Público) began as part of broader efforts by Codeando México and partner organizations to address a major infrastructure gap in Mexico: the absence of standardized, open, and reusable public transport data in most cities. The project builds on earlier collaborative mapping initiatives such as Mapatón Ciudadano, which experimented with participatory transport mapping and GTFS generation in cities where transit information either did not exist digitally or was fragmented and inaccessible.

The project is primarily intended for municipalities, mobility agencies, civic organizations, researchers, developers, and transit users. One of its core goals is lowering the technical and operational barriers that prevent local governments from publishing transport data. The methodology includes route mapping, GTFS modeling, validation workflows, open licensing guidance, and publication practices that municipalities with limited technical capacity can realistically adopt.

Its impact has been both technical and institutional. HDTP and related initiatives have produced GTFS datasets for multiple Mexican cities including Toluca, Oaxaca, Salina Cruz, Jilotepec, Zamora, and Zitácuaro. In some cases, these datasets have enabled integration into navigation and journey-planning tools, including Google Maps and multi-city transit applications. The work has also supported urban planning, mobility analysis, and collaborative mapping ecosystems using OpenStreetMap and open-data standards.

The project also contributes to a broader cultural shift around mobility data in Mexico. Historically, many transport systems operated without machine-readable route information or public APIs. By publishing open GTFS feeds and methodologies, HDTP has helped create infrastructure that developers, analysts, and civic-tech communities can build upon.

People can help in several ways:

• municipalities can collaborate by opening and validating transit data,
• volunteers can participate in route mapping and OpenStreetMap contributions,
• developers can build tools and integrations using GTFS feeds, researchers and journalists can use the datasets for analysis and accountability,
• and civic organizations can support training, documentation, and community workshops around open mobility data.
