Evaluación de la seguridad vial de la carretera CV-31 entre el P.K. 0+000 y el P.K. 5+000 (provincia de Valencia)

[ES] El presente Trabajo de Fin de Máster tiene como objetivo evaluar la seguridad vial de la carretera CV-31 perteneciente a la red de carreteras de la Generalitat Valenciana en el tramo que discurre entre el enlace de conexión con la autovía CV-30 y la carretera CV-310. Para ello se va a utilizar la nueva metodología propuesta por la Unión Europea Network Wide Road Safety Assessment - Methodology and Implementation Handbook (NWA). Esta metodología abarca dos enfoques; enfoque reactivo, analizando la información sobre accidentalidad, y enfoque proactivo, segmentando y analizando todos los elementos y características de la carretera. Se evaluará un tramo de autovía sin de accesos con las características propias según la Norma 3.1-IC, Trazado, y otro segmento clasificado como carretera convencional, con accesos a nivel, pudiéndose comparar todas las situaciones y los diferentes resultados que se obtengan.

[EN] Due to the growing global concern about high accident rates, particularly the fatality rates in countries, it has been determined that one of the goals for the SDGs, along with the World Health Organization, is to promulgate the Global Plan for the Decade of Action for Road Safety 2021-2030. At the European level, the Global Road Safety Strategy has been defined. These tools aim to reduce the number of accidents and the level of fatalities. Part of the key elements to achieve these objectives are the tools for road safety assessment of the road network infrastructure. In this context, the European Union promotes the Network-Wide Assessment (NWA) methodology, a tool aimed at evaluating road safety levels. The NWA combines reactive and proactive assessment approaches. The first approach focuses on analysis through accident data, while the second evaluates geometric aspects. A third integrated approach is added, allowing the classification of the road based on risk levels into prioritization levels for action on the evaluated road. This work conducts a road safety assessment of the CV-31 road from PPKK 0+300 to PPKK 4+225 and its extension from PPKK 0+000 to PPKK 0+750 of the CV-310 using the Network-Wide Assessment (NWA) methodology. It provides a description of the methodology from the justification for the development of NWA, the differences in its various previous versions, and a description of each development process of the methodology. For the reactive approach, the segmentation process of the road is described. The various considerations and recommendations provided by the methodology s guidelines are explained. Additionally, the type of data collection and the processing of this information to generate safety levels from the reactive approach are detailed, whether it be accident data or the selection of the Reference Population Level. The procedure to follow is the calculation of safety parameters to finally establish the Road Safety Range. As for the second approach, NWA-Proactive, similar to the reactive approach, the segmentation criteria are established, followed by an explanation of the geometric parameters to be evaluated, the obtaining of this information, and the estimation of the factors provided by the methodology to ultimately estimate the score for each segment. The results of this assessment will help identify the most critical sections in terms of risk and prioritize the necessary interventions to improve road safety. This methodology offers a comprehensive approach that combines accident analysis with the evaluation of the route s geometric elements, providing a solid foundation for decision-making in road network management.
