Uso del modelo iRAP para la evaluación de seguridad vial y propuesta de mejoras de bajo costo en el tramo Valladolid-Palanda (Zamora Chinchipe, Ecuador)

Abstract

Abstract: Rural roads tend to have high levels of accidents, due to factors such as: high slopes, high traffic, deterioration of pavements, etc. To evaluate the safety of these roads, the methodology proposed by the International Road Assessment Program (iRAP). This methodology proposes an analysis for each user of the road, such as vehicle occupants, motorcyclists, cyclists and pedestrians, using star ratings from 1 to 5, where 1 represents greater danger and 5 represents greater safety. Consequently, the main objective is to evaluate road safety in the sections of the Valladolid-Palanda-Agua dulce highway and propose economic improvements. To achieve this, They investigated current conditions in the area both in situ and online. Then, it was evaluated the current condition and road countermeasures were applied to improve its rating. With base in the accidents that occurred in the study area and proposed countermeasures, a budget and the level of risk reduction. Where, the most significant variable for improve the condition of the road, was the placement of metal road guards on the sides of the curves.
