Identifying Pavement Improvement Projects for Enhanced Safety

The research teams will develop a method and tool for analyzing safety-related pavement data to identify candidate pavement safety projects, such as cross-slope improvement projects and flushing treatment projects. The research teams will assemble a dataset containing comprehensive data on the pavement, site condition, and crashes for a representative sample of on-system roadways. The research teams will conduct a comprehensive analysis of the integrated dataset to identify critical combinations and thresholds of pavement conditions that may pose a safety hazard and use these factors to assess pavement susceptibility to crashes. The research teams will quantify the pavement crash susceptibility based on measurable pavement characteristics such as cross-slope, geometrics, distresses (e.g., rutting, flushing), skid resistance, and roughness. Finally, the research teams will develop a data analysis and visualization tool for assessing pavement crash susceptibility and recommending solutions to reduce crash risks. Texas Department of Transportation's (TxDOT’s) districts will be able to use this tool to identify potential site-specific crash contributing factors and proactively select appropriate pavement safety improvement projects.
