Signal Four Analytics（traffic safety-focused)
Signal4 Analytics is an interactive, web-based system designed to enhance traffic information sharing in the state of Florida. It supports crash visualization, mapping, and analysis for transportation planning agencies, law enforcement, traffic engineers, and research institutions. The system’s geospatial analysis of crash data informs safety decision-making and facilitates evidence-based transportation planning.
The data used to generate geospatial results in the Signal4 system includes over 7 million crash records, over 40 million traffic citations, roadway information, etc. Signal4 Analytics also maintains the publicly available Florida Traffic Safety Dashboard, which provides crash data across Florida.
The products are used by Florida transportation agencies and promoted by the US Department of Transportation (USDOT). This decade-long project received the National Best Practices in Traffic Records Award at the Traffic Records Forum 2025, given by the Association of Transportation Safety Information Professionals (ATSIP).
