This dissertation investigates wrong-way crashes, which are 27 times more deadly than other crash types. Using GIS and statistical modeling in South Florida, the study identifies roadway design, traffic conditions, and impaired driving as key risk factors. Findings highlight lighting, wider medians, and early police intervention as life-saving prevention strategies.

This research develops new height–diameter models for key Spanish tree species to improve forest management planning. While initial models fit data visually, statistical performance remains weaker than current equations. Future work will incorporate stand-level variables such as basal area and dominant height to enhance accuracy and reduce estimation errors.
