Summary
This research addresses the critical issue of traffic safety disparities in Native American communities, particularly in New Mexico, where official datasets often under-report collisions and fail to capture non-fatal incidents. The study is motivated by the disproportionate risk faced by tribal members, who experience collision rates approximately four times higher than non-tribal populations due to systemic disinvestment, limited infrastructure, and high pedestrian reliance. To bridge this data gap, the authors developed a web-based crash reporting and analysis tool grounded in Community-Based Participatory Research (CBPR) and Volunteered Geographic Information (VGI). The primary objectives were to explore how VGI can supplement under-reported traffic data and to examine how an online mapping portal can foster community engagement and informed decision-making regarding local safety hazards. The methodology involved modifying an existing dynamic crash-mapping platform to incorporate VGI functionality, allowing residents to submit crash reports via an interactive map interface. The system was designed with a standardized reporting form aligned with New Mexico Department of Transportation datasets to ensure consistency. To address common VGI quality concerns, the platform implemented robust user authentication using hash-salt techniques, IP-based geolocation to detect malicious or automated submissions, and a dedicated Quality Assurance/Quality Control (QA/QC) workflow where trained users review and approve entries. Additionally, the tool integrated web analytics to monitor user behavior and site engagement, alongside gamification elements such as leaderboards to incentivize sustained participation and foster a sense of civic ownership. The findings demonstrate that the platform successfully integrates community-driven data collection with rigorous quality control mechanisms. By leveraging IP geolocation and manual review, the system mitigates risks associated with inaccurate or malicious contributions, ensuring data integrity. The inclusion of gamification and accessible web analytics provided insights into user engagement patterns, supporting iterative improvements to the platform. The tool empowers local residents to directly contribute to and visualize collision data, thereby supplementing formal records that typically exclude less severe crashes. This approach not only enhances the spatial resolution and completeness of traffic collision data but also actively engages communities in identifying high-risk areas. The significance of this work lies in its potential to promote more equitable infrastructure planning by providing localized, community-informed data for historically underrepresented populations. The study offers a scalable, open-source model for improving traffic safety through civic engagement, addressing systemic inequities rooted in historical practices like redlining that have led to neglected infrastructure in minority areas. By enabling communities to participate directly in data collection, the tool supports the identification of safety hotspots and informs resource allocation. Future work aims to expand outreach efforts and conduct deeper statistical analyses comparing VGI data with formal state records, further validating the utility of community-driven approaches in enhancing transportation safety and equity.
