Propuesta de mejoras de bajo coste en la seguridad vial de un tramo de carretera rural la saquea muchime desde la abscisa 0+000 a la abscisa 20+000 de la provincia de Zamora Chinchipe utilizando la metodología Irap

Abstract

Abstract: Traffic accidents represent a serious problem for societies, causing significant economic and social damage. In this work, road safety was evaluated of the La Saquea - Muchime road, which is a two-lane rural road located in the province of Zamora Chinchipe in the south of Ecuador, through the iRAP methodology that evaluates road safety based on the existing road infrastructure. We first proceeded to collect information in the field by recording a georeferenced video using Timestamp Camera Free application in which all features were recorded geometric characteristics of the infrastructure, and important data such as the TPDA (Transit Annual Daily Average) and operating speed. The evaluation is carried out every 100 meters By using ViDA software, security is analyzed for all of the following users: vehicle occupants, motorcyclists and pedestrians. The methodology is based on a system of star rating (SRS), where one star indicates the least safe road and five stars the safest. As a result of the evaluation, critical points were identified as poor signage, inadequate road width, shoulders, and a high level of lateral severity for driver and co-pilot. Significant deterioration of road infrastructure was evident and a high risk for users. Countermeasures are proposed to improve infrastructure road according to the iRAP methodology. This methodology has proven to be valuable in evaluating the road safety and generate effective investment plans, allowing prioritization of interventions and optimize resources intended to improve road safety.
