Participatory Transport Mapping in Zamora, Mexico

HOT Project



Mid-sized Mexican cities face challenges due to insufficient transport data. Our initiative with OpenStreetMap, Co-Mapper, and Codeando México aims to create accurate maps for better urban planning and mobility. By engaging local stakeholders in collaborative mapping, we seek to empower communities and improve quality of life in Zamora.


Zamora, a municipality in western Michoacán with 150,000 residents, faces significant challenges due to the absence of precise transport data. Despite 80,000 people relying on public transport daily, there is no reliable information about the system. This gap hampers effective planning and decision-making, leading to inefficient routes, traffic congestion, and limited transport options. For residents, this lack of information complicates accessing reliable mobility options, making daily commutes difficult, costly, and unsafe. Addressing this issue is critical for updating transport policies and ensuring equitable access to mobility solutions.

The initiative leverages the expertise of OpenStreetMap (through HOT, Co-Mapper, and specialized OSM contributors), Trufi, and Codeando México to create and utilize comprehensive transport data. It collects, verifies, and processes the data before delivering it to Trufi for integration into OSM. The project employs a participatory mapping methodology, involving local stakeholders and university students in data collection and validation processes. The methodology includes:

  1. Preparatory Mapping: Using OSM to map the city’s road infrastructure, engaging specifically trained students for quality data collection.

  2. Complementary Cartographies: Adding detailed road characteristics, cycling paths, special lanes, and key points of interest.

  3. Public Training: Educating participants in mobile technologies for transport route mapping during peak and off-peak hours.

  4. Shared Coordination with Locals: Appointing a knowledgeable local leader from the municipality to oversee project commitment.

  5. Field Data Collection: Coordinated by local leaders or supporting organizations (HOT, Codeando México, Trufi), ensuring data validation.

  6. Data Processing: Involving trained students in data processing and training new students, led by Trufi.

  7. Integration: Incorporating data into the Rutómetro app, a Mexican instance of the Trufi-App.

  8. Strategic Support: Defining complementary mappings and scaling to neighboring cities.

  9. Public Outreach: Broad dissemination to local and state governments, and national transport authorities.

The project will result in the first comprehensive transport database for Zamora and its metropolitan area, including Jacona. This base map will enhance the OSM infrastructure, providing detailed data on streets, names, directions, and key points of interest. Local and state governments will gain new insights for transport system regulation, planning, and improvement.

Codeando Mexico’s Rutómetro app will integrate data from Zamora, offering an attractive and practical solution for the population that does not exist nowadays. Successful mapping projects in these cities will pave the way for expanding the Rutómetro app to more states, leveraging GIZ funding for broader impact.

Key objectives and impacts include:

  1. Enhanced Cartography: Improve the municipality’s cartography on OpenStreetMap, focusing on street layouts, directions, and detailed infrastructure data.

  2. Digitized Transport Information: Digitize information for 43 public transport routes, including both formal and informal stops and associated infrastructure.

  3. Open Data Generation: Generate and open data in standard formats for broader use, including publication on any popular platforms.

  4. Improved Data Availability: Enhance data availability to support better planning and provide citizens with accurate mobility information.

  5. Encouraged Public Transport Use: Promote public transport over private vehicle use, benefiting the environment and enhancing the quality of life. Support the government in improving service delivery.

  6. Long-term Economic and Social Benefits: Improve access to economic opportunities and city services, particularly benefiting women and youth, the primary public transport users.

  7. Alignment with UN SDG 11: Support the United Nations Sustainable Development Goal 11 to make cities inclusive, safe, resilient, and sustainable, and target 11.2 for safe, affordable, accessible, and sustainable transport for all.


Key lessons from the project include the importance of continuous local engagement and the benefits of integrating transport data into accessible digital platforms.
