Análisis de la velocidad en carreteras rurales de dos carriles en entornos montañosos. Caso estudio Loja Catamayo (tramo 1)

Abstract

Abstract: Speed ​​analysis on mountainous roads is important for road safety, as it is influenced by factors such as road design, environmental conditions, and driver behavior. In Ecuador, the mountainous geography creates high-risk roads, and the lack of studies on the speed of heavy vehicles in these areas makes this topic of great importance. This study analyzed the speed of heavy vehicles on the Loja-Catamayo Highway using GPS data from the Provincial Government of Loja, processed with MINITABS. Statistical methods such as ANOVA, Kruskal-Wallis, Z-Score, and correlation analysis were applied. The influence of curve radius and slope on speed was evaluated. The results confirmed that radius has a direct relationship with speed, while slope has an inverse effect, reducing it on ascents and increasing it on descents. These findings underscore the importance of considering these factors in road design to improve traffic safety and efficiency.
