Análisis comparativo de las normas Nevi-2012 y el reglamento de la Ley de Sistema de Infraestructura Vial del Transporte Terrestre vigente

Abstract

This thesis analyzes the differences and opportunities for improvement within the regulatory framework of Ecuador's road infrastructure, specifically between the Ecuadorian Road Standard (NEVI-2012 Volume 2A) and the Regulations of the Organic Law of the National Road Infrastructure System for Land Transport. It also compares these with international standards such as the American Association of State Highway and Transportation Officials (AASHTO) from the United States, Colombia’s National Roads Institute (INVIAS), and Peru’s Geometric Design of Roads Handbook. The aim is to identify strengths and weaknesses to plan necessary updates to the Ecuadorian regulations, ensuring a more appropriate, modern, and efficient road infrastructure system. Among the main discrepancies is the use of the Annual Average Daily Traffic (AADT) and the Projected Annual Average Daily Traffic (PAADT) as road classification criteria. While the regulations use the AADT to reflect current traffic, this parameter is insufficient for modern vehicular demands. According to the geometric design, the regulations lack detailed technical specifications, unlike the NEVI standard and the international comparison standards, which incorporate clear criteria such as radius of curvature, maximum slopes, lane widths, and environmental sustainability data. The study proposes updating the regulations to incorporate the PAADT as a modern road planning criterion and technical parameters for geometric design. This would ensure that Ecuadorian regulations are more efficient and compatible with international standards.
