Determination of Geometric and Signaling Hazards on Interurban Roads: Critical Perspective for Optimizing Safety on Route 2502

Abstract

Route 2502, between PR 5+000 and PR 28+000, is a high-traffic road corridor on the Pan-American Highway, with a high risk of accidents due to the interaction of different road actors. This study identifies critical accident areas, analysing geometric and signalling factors to propose corrective measures to improve road safety. Through the analysis of statistical data, signage inventories and road safety audits, the main risk points and their causes were determined. The results show the need for interventions in signage, road geometry and speed control to reduce the vulnerability of drivers and pedestrians. This work provides key tools for the planning of mitigation strategies in road infrastructure.
