Mining and Analysis of Traffic Safety and Roadway Condition Data

Exploration of associations between road conditions and traffic accidents

Decision makers working to improve transportation systems must constantly balance the need to improve roadway safety through infrastructure investment with constraints of available resources. This project attempts to apply advanced data analysis techniques across independent datasets containing traffic accident data and roadway condition data to explore the additional information available to transportation decision makers through the integration of these datasets. The data used in this project for analysis included roadway condition data collected by the Alabama Department of Transportation and traffic accident data available in the Critical Analysis Reporting Environment (CARE) system. This project used data mining techniques to examine these possible relationships between roadway data and traffic safety data, and on a general level attempted to conclude whether discernable and predictable associations exist that may be identified through analysis of the roadway condition and reported traffic accident events.
