Evaluating Cross-Slope Safety Impacts on Freeways in Georgia

The main objective of this proposed project is to quantify the relationship between freeway cross-slopes and grades and crashes during wet-weather conditions. Given the study’s focus on evaluating the safety impacts of cross-slopes, the analysis will concentrate on tangent freeway segments, as these are more representative of basic freeway sections and are subject to consistent cross-slope design guidance.
