Ítem Acceso Abierto Comparación de costos entre pavimentos flexibles y rígidos en la ciudad de Cuenca, Ecuador(Universidad Católica de Cuenca., 2025) Maruri Ocampo, Kevin Santiago; Kevin Santiago, Pedro José; Maldonado Noboa, César Humberto; 0706687761; 0105501134; LeonardoThis study compares the costs associated with the construction, maintenance, and lifespan of flexible and rigid pavements in road projects in Cuenca, Ecuador. A comprehensive analysis, evaluated factors such as material production, transportation, laying, placement, and maintenance, considering the geographical and logistical characteristics of the three parishes: Ricaurte, Baños, and Sayausí. The methodology included calculating unit prices (UP), optimizing transportation routes using tools like Google Maps and ArcGIS, and assessing operating costs in different scenarios. The results showed that although rigid pavements require an initial investment of 30-40% higher, they offer a longer lifespan (20-30 years) and lower maintenance costs, making them ideal for urban areas with heavy traffic. On the other hand, flexible pavements, with lower initial costs, require frequent interventions, increasing their accumulated expenses by 15-25% over 15 years. Transportation distances had a critical impact: in remote parishes like Baños, logistical costs increased by up to 20% compared to areas close to material sources, such as Ricaurte. The study concludes that the pavement selection should prioritize the specific context of each project, balancing initial costs, durability, and resource accessibility. These findings provide a technical basis for decision-making in road infrastructure in Cuenca, promoting sustainable and economically efficient solutions.Ítem Acceso Abierto Determinación de las tasas de crecimiento vehicular de la Provincia del Azuay para proyecciones de tráfico(Universidad Católica de Cuenca., 2025) Solano Guevara, Pedro Javier; Verdugo González, Carlos José; Maldonado Noboa, César Humberto; 1400976591; 0107170995This research describes the problematics of accelerated vehicle fleet growth in the province of Azuay, focusing on the city of Cuenca and its impact on urban mobility planning. A quantitative analysis of vehicle growth behavior between 2010 and 2022 was conducted based on the compilation of historical vehicle registration and population data from official sources such as National Institute of Statistics and Censuses (INEC, by its Spanish acronym), Municipal Public Company for Mobility, Transit, and Transportation (EMOV EP, by its Spanish acronym), Association of Automobile Companies of Ecuador (AEADE, by its Spanish acronym), and the Ministry of Transport and Public Works (MTOP, by its Spanish acronym). In Azuay, compound annual growth rates were calculated by vehicle type, while in Cuenca, rates were calculated for total vehicles, and vehicle fleet projections were developed until 2042 using statistical models and linear equations. The study identified factors influencing vehicle growth, including urbanization, fuel subsidies, economic growth, and migration. Likewise, the negative impacts of increased vehicle fleets were analyzed, such as traffic congestion, environmental pollution, infrastructure deterioration, and socioeconomic effects. The results show sustained growth in the vehicle fleet, with motorcycles being the segment with the greatest proportional increase, followed by SUVs and trucks. The projections anticipate future mobility scenarios and offer key inputs for formulating public policies for more sustainable and equitable mobility. Finally, they highlight the urgent need to strengthen road infrastructure, optimize public transportation, and promote clean transportation alternatives in the province.Ítem Acceso Abierto Evaluación de la consistencia en el trazado geométrico de 2 vías rurales en terrenos montañosos de la Provincia del Azuay(Universidad Católica de Cuenca., 2025) Gualan Andrade, Johana Priscila; Maldonado Noboa, César Humberto; 1401062169; LeonardoThis research evaluates the consistency of the geometric design of two rural roads in the parish of Ricaurte, province of Azuay, by analyzing operating speeds to identify inconsistencies that affect road safety and propose improvements. In Ecuador, traffic accidents on rural roads are associated with a mismatch between the design speed and the actual operating speed, which leads to abrupt changes in driving behavior and increases the risk of accidents. The justification for this study is based on the need to optimize road infrastructure to reduce accidents and ensure safe and efficient circulation. The methodology combines quantitative and qualitative approaches, using topographic surveys with RTK, geometric reconstruction in AutoCAD Civil 3D, and field speed measurements at the center of curves. The operating speed was determined based on the routes taken in the study sections and compared with the established design speed, following the criteria proposed by Lamm to evaluate the consistency of the geometric layout. The Bibin Road section features a geometric design that aligns with drivers' expectations due to the good consistency of the road. In contrast, the Ricaurte-Llacao road lacks a good geometric design since there are minimal radii which causes drivers to make changes in their operating speed due to the poor consistency of the road.
