title: Cycling accidents in Guadalajara, Mexico

description: A High-Resolution Geospatial Dataset of Cyclist-Involved Crashes and Segmented Cycling Infrastructure in the Guadalajara Metropolitan Area (2015–2024)

This repository contains the data and documentation accompanying the Data in Brief article of the same name. It provides a processed, analysis-ready dataset linking 774 cyclist-involved crash records to a uniformly segmented cycling network in the Guadalajara Metropolitan Area (AMG), Mexico.

Keywords: Cyclist safety; Traffic accidents; Urban mobility; Latin American cities; GIS

Key Features



High-Resolution Granularity: The cycling network is segmented into ~20-meter micro-segments (13,380 units), offering 5x-25x greater precision than traditional street-level analysis.

Spatial Integration: Each crash record is spatially joined to its nearest infrastructure segment (IDSegmento), allowing for precise hotspot detection.

Longitudinal Coverage: Comprehensive records spanning nearly a decade (2015–2024).

Ready-to-Use: Data is cleaned, validated, and enriched with derived variables (e.g., Concentracion_accidentes).

2. File Guide: Which file should I use?



Data Scientists & Researchers: Use cyclist_accidents_segmentid_frequency.csv for statistical modeling. A bilingual Starter Notebook (starter_notebook.ipynb) is provided in the 5. Visualizations folder to help you load and explore the data immediately.

Urban Planners & GIS Analysts: Use segmentos_ciclovias.csv to map the infrastructure network and identify high-risk segments.

Policymakers: Open accidents_heatmap_FULL.html (located in the 5. Visualizations folder) for an interactive, no-code view of crash hotspots.


3. Documentation for Non-Spanish Speakers

The original data preserves Spanish variable names to maintain source fidelity. To assist international researchers, we provide:



code_crosswalk.csv: A dedicated file mapping all Spanish variable names to English aliases and descriptions (located in 2. Documentation and metadata).

starter_notebook.ipynb: Fully bilingual (English/Spanish) comments and instructions.


4. Reproducibility

The entire dataset allows for full reproduction from the raw sources. The processing pipeline is available in the 4. Scripts folder, and the software environment is frozen in environment.txt.
