Tipo de ítem: Ítem , Estudio de tránsito y propuesta de mejora de la intersección av calle 80-conexión Lisboa en la ciudad de Bogotá(Universidad Santo Tomás, 2026-10-16) Ramos Barajas, Jonatan Alexander; García Quintero, Jesús David; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001912257; https://scholar.google.com/citations?user=yep-lzAAAAAJ&hl=es&oi=ao; https://orcid.org/0000-0003-0605-6630The implementation of Bogotá's first Land Development Plan (POT), established under Decreto 619 of 2000 and fully enacted in 2004, introduced stringent land-use restrictions. These regulations restricted industrial development and high-environmental-impact zones within the city's central areas, progressively driving the relocation of warehouses, distribution centers, and manufacturing plants toward the western periphery—such as the Fontibón Free Trade Zone—and adjacent municipalities of the Bogotá Savanna (including Funza, Mosquera, and Cota). While this regional industrialization has stimulated the labor market for both suburban residents and capital commuters, it has simultaneously caused operational demand on Avenida Calle 80 to severely outstrip its service capacity during peak hours. As a primary western arterial exit, Calle 80 provides a critical cross-city connection, intersecting high-capacity corridors such as Avenida NQS, Avenida 68 (currently undergoing intervention for a new TransMilenio trunk line), Avenida Boyacá, and Avenida Ciudad de Cali. Additionally, it features exclusive Bus Rapid Transit (BRT) lanes that converge at Portal 80, an intermodal hub facilitating commuter bus routes to the surrounding Savanna municipalities. In this context, critical traffic flows are observed during the morning peak from 6:00 a. m. to 8:00 a. m., a window where vehicular demand exceeds the infrastructure's design capacity. This bottleneck is further exacerbated by a roadway bottleneck that narrows the layout from four to two lanes, resulting in a deficient Level of Service (LOS) that is highly vulnerable to traffic incidents or mechanical failures. The direct impact of this bottleneck is reflected in disproportionately prolonged travel times: whereas a trip under free-flow conditions between Portal 80 and the Siberia roundabout takes approximately 15 minutes, historical Google Maps server metrics indicate that during critical operational windows, travel times escalate to between 60 and 90 minutes. Consequently, this research paper proposes the development of two geometric design alternatives aimed at optimizing traffic circulation and operational capacity along the corridor. These alternatives will be formulated based on a traffic diagnosis of current conditions and subsequently evaluated against projected traffic volumes using traffic micro-simulation. The methodological objective is to contrast their operational performance to select the technically optimal solution that addresses the mobility requirements for users at the Avenida Calle 80 - Transversal 120 (Lisboa connection) intersection.Tipo de ítem: Ítem , Propuesta de mejora vial para la implementación de una ciclo-infraestructura.

This growth has been supported by the existence of an extensive network of bike lanes distributed across different areas of Bogotá, which contributes to improving the safety, continuity, and quality of cycling routes, thereby encouraging its daily use. However, there are still segments with deficiencies in connectivity and operational conditions that limit the potential of this mode of transport. In this context, the need to implement new cycling infrastructure is addressed through the development of a road improvement proposal aimed at strengthening integration with existing bike lanes within the study segment. This proposal seeks to optimize mobility, reduce conflicts among road users, and promote a safer, more efficient, and sustainable transportation system in the analyzed area.Tipo de ítem: Ítem , Metodología para el cálculo de un índice de movilidad urbana sostenible, caso de estudio: Bogotá(Universidad Santo Tomás, 2026-10-15) Rivera Guapo, Diego; González Camargo, Carlos Alberto; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000628824; https://orcid.org/0000-0003-1305-0966The methodology for the calculation of the Sustainable Urban Mobility Index of Bogotá (IMUS.BOG) is framed as a measurement tool for assessing the level of compliance with sustainable urban mobility in the city of Bogotá, and each of its study dimensions: environmental, social and economic; serving as a monitoring and evaluation instrument for district entities, stakeholders and the general public. The base structure of this index is composed of a selected set of 27 indicators, made up of indicators validated in the international context of Sustainable Urban Mobility Index (SUMI) modelling, pre-selected through the bibliographic frequency analysis technique, as well as strategic indicators from the Plan de Movilidad Sostenible y Segura de Bogotá (PMSS), issued through Decreto 497 of 2023. All indicators selected for the construction of the IMUS.BOG comply with the principles of the SMART Methodology. For the normalization of the selected indicators, and in accordance with their nature and availability of historical records, the Min-Max Scaling technique was applied, given its qualities for the easy interpretation of normalized data (transformed to the dimensionless range between 0 and 1) and the linkage of normative reference limits aligned with the sustainability standards defined in district, national or international regulations, prioritizing the targets defined by the PMSS and the Colombian regulatory framework in that order. For indicators lacking standardized reference limits established by normative documents, the limit values corresponded to the most unfavorable historical records in terms of sustainability registered in the city, taking these values as points of no return. Once the normalized values were obtained, a two-level hierarchical aggregation structure was applied, using equal weighting at each level, a structure that stands out for its practicality, ease of interpretation of results and wide acceptance in academic literature. The first level consisted of aggregating the indicators of each study dimension to obtain their sub-indices IMUS.BOGa, IMUS.BOGe and IMUS.BOGs. The second level applied the same technique to aggregate these sub-indices, thus obtaining the global IMUS.BOG value, yielding the following results for the year 2025: IMUS.BOGa=0.844 (optimal), IMUS.BOGe=0.643 (satisfactory), IMUS.BOGs=0.516 (intermediate) and IMUS.BOG=0.668 (satisfactory). Finally, the robustness analysis validated the stability of the base methodology, obtaining satisfactory results when using various aggregation alternatives and weighting methods with balanced distributions, such as equal weighting and manual assignment.Tipo de ítem: Ítem , Evaluación técnica con enfoque cualitativo y cuantitativo de los daños generados por un sismo de magnitud 6,5 en la infraestructura vial del corredor Villavicencio - Yopal(2026-09-07) Andrade Ostos, Nicolás; Ramírez Rubiano, Lizeth Camila; Díaz Cruz, Luis Fernando; Universidad Santo Tomas; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000140075; https://scholar.google.com/citations?user=c6NZ2tDmin0C&hl=es; https://orcid.org/0000-0002-1843-2501This study presents a qualitative and quantitative technical assessment of the damage caused by the Mw 6.5 earthquake that occurred on June 8, 2025, to components of Functional Units 2 and 3 of the Villavicencio–Yopal road corridor. The research was conducted as an applied, descriptive-analytical, retrospective, and non-experimental case study based on the integration of field inspections, pre-event records, specialized tests, International Roughness Index (IRI) measurements, Falling Weight Deflectometer (FWD) testing, ground-penetrating radar data, and structural and geotechnical modeling. The assessment covered bridges, box culverts, slopes, retaining structures, embankments, bridge approaches, drainage works, pavements, and construction and demolition waste disposal sites. The results showed that the observed damage was not associated with a single mechanism but with the interaction among seismic demand, component stiffness, ground conditions, and drainage performance. The most relevant findings included damage to bridge bearing and seismic restraint systems, widespread deterioration of the support system at the Alto de La Guala slope, the need to reconstruct 13 of the 14 affected culverts, and changes in the functional and structural indicators of the pavements. Differential displacements, loss of confinement, soil–structure interaction, drainage disruption, and reduced functional or structural capacity were identified as recurrent damage mechanisms. It is concluded that the post-earthquake assessment of road corridors requires an interdisciplinary approach that integrates pre-event conditions, technical evidence, observed damage, damage mechanisms, and proposed interventions to guide the restoration of safety, stability, and serviceability conditions.Tipo de ítem: Ítem , Propuesta de diseño de la intersección variante Cota entre el K0+00 hasta el K4+900 sentido sur – norte del Departamento de Cundinamarca.(Universidad Santo Tomás, 2026-06-30) Ospina Caro, Jimena Astrid; Vargas Vargas, Wilson Ernesto; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000494135; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001724726; https://scholar.google.com/citations?user=9gKVKZ4AAAAJ&hl=es&oi=aoThis research aims to propose a geometric improvement alternative for the existing roadway configuration of the Variante Cota corridor, ensuring adequate service levels throughout the operational lifespan of the infrastructure. To achieve this objective, a comprehensive technical assessment was conducted based on the design information provided by the Instituto de Caminos y Construcciones de Cundinamarca (ICCU). The evaluation of previous studies and operational data enabled the identification of critical performance deficiencies, particularly those associated with service level degradation and excessive travel times within the corridor. These conditions have negatively impacted both commercial transportation efficiency and the quality of life of residents and frequent users of theroadway. Based on the diagnostic findings, a new intersection configuration was modeled to improve operational performance within the study area. The proposed alternative was developed through geometric redesign and traffic simulation processes using specialized engineering software tools, including VISSIM and Civil 3D. The results demonstrate the technical feasibility of implementing a geometric solution capable of enhancing mobility conditions and optimizing service levels along the Variante Cota corridor.Tipo de ítem: Ítem , Diseño de una metodología para la determinación del modo de operación de un sistema semafórico en el corredor avenida calle 80 entre carrera 112 y carrera 120 en la ciudad de Bogotá D.C.(Universidad Santo Tomás, 2026-05-19) Vidal Esquivia, José Mario; Roqueme Salazar, Christian; García Quintero, Jesús David; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001912257; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001819414; https://scholar.google.com/citations?user=yep-lzAAAAAJ&hl=es&oi=ao; https://orcid.org/0000-0003-0605-6630This research aims to design a methodology to determine the most appropriate operating mode for a traffic signal system in urban corridors, using Avenida Calle 80 between Carrera 112 and Carrera 120 in Bogotá D.C. as a case study. The study arises from the need to improve traffic management in areas with high vehicular demand, public transport, freight transport, pedestrians, and cyclists, where traditional traffic signal schemes may be insufficient to respond to traffic variability. The research included the characterization of the current traffic signal system, the analysis of the physical and operational conditions of the corridor, and the evaluation of indicators such as saturation, demand variability, road safety, and coordination between intersections. Subsequently, a five-step methodology was applied to assign traffic signal operating modes, including fixed-time, actuated, responsive, and adaptive control, according to the actual conditions of each intersection. Additionally, a microscopic traffic simulation was developed for both the current and optimized scenarios in order to compare the operational performance of the corridor. The results show that traffic signal optimization improves the average network speed, reduces delays, strengthens coordination between intersections, and increases the efficiency of vehicular flow processing. Therefore, the proposed methodology represents a useful technical tool to support decision-making in urban traffic signal management and may be replicated in other corridors with similar characteristics.Tipo de ítem: Ítem , Análisis del riesgo de redes según lineamiento del conpes 3760 de 2013 y lo regulado en la ley 1682 de 2013 en cuanto a redes de servicios públicos, en lo proyectos de app “entrada norte fase II” del distrito capital y tercer carril Bogotá – Girardot(Universidad Santo Tomás, 2026-05-06) Barbanti Mansilla, Carolina Jackeline; Bogoya Castaño, Álvaro; Forero, Silvia Pilar; Universidad Santo TomásThe road network in Colombia forms the essential foundation for urban development, enabling accessibility, sanitation, water management, energy distribution, and communications, among other aspects. In this regard, the core networks for transportation and services—such as roads, potable water, sewage, electricity, gas, and telephony—support the movement of people, the supply of goods, the provision of basic utilities, gas transport, and the disposal of urban waste (Departamento Nacional de Planeación [DNP], 2013). Nevertheless, the progress of road infrastructure projects nationwide has encountered numerous hurdles that have delayed their completion, adversely affecting the modernization of the country's highway system. In response to this situation, the government enacted reforms to transportation projects through Law 1682 (2013), a pivotal step given Colombia's substantial lag in infrastructure compared to other countries. The nation ranks 85th in overall infrastructure quality and 124th in road quality out of 144 countries (Ley 1682, 2013). This legislation creates a regulatory framework that equips the sector with tools to address the country's evident infrastructure shortfall, fostering the construction and upkeep of a modern, efficient transportation network. The enactment of Law 1682 of 2013 lays the groundwork to consolidate scattered regulations, eliminate unnecessary procedures, enhance project preparation, reduce legal disputes, and build a stronger institutional framework to lead infrastructure works across all transport modes. Its implementation in projects featuring urban segments—such as Bogotá's North Exit (Phase II) and the Bogotá-Girardot Third Lane—presents challenges in execution, with the following priorities standing out: • Upgrading physical and technological infrastructure on highways. • “Better mobility for all.” • Integrated monitoring, communications, and citizen service system (Command and Control Center). Therefore, it is critical to implement the Infrastructure Law in Public-Private Partnerships (PPPs) with urban stretches, providing mechanisms to overcome key bottlenecks that have hindered the speed and feasibility of these transport projects: land acquisition, environmental licenses, mining permits, and public utility connections, among others.Tipo de ítem: Ítem , Aplicación de la metodología BIM en la planificación, simulación y presupuestación de una vía terciaria sector el paraíso, municipio de la Jagua del Pilar, La Guajira(Universidad Santo Tomás, 2026-03-16) Neira, Maryury Aishell; Cubillos Gonzalez, Rolando Arturo; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001361734; https://scholar.google.com/citations?user=77ye_gwAAAAJ&hl=es&oi=ao; https://orcid.org/0000-0002-9019-961XRoad infrastructure in Colombia faces significant challenges, particularly in the construction and maintenance of the tertiary road network, which is essential for connectivity and the economic development of rural areas. In this context, the Building Information Modeling (BIM) methodology emerges as an innovative alternative that enhances planning, simulation, budgeting, and risk management in infrastructure projects. This research project focuses on the application of BIM principles in the construction of the tertiary road El Paraíso, located in the municipality of La Jagua del Pilar – La Guajira, with the purpose of demonstrating its effectiveness as a technical and strategic tool for the planning and control of road works. Through a case study, 3D models and 4D–5D simulations were developed to compare the conventional project execution method with the BIM-based approach, showing an average reduction of 16.7% in execution time and 10% in direct costs. Additionally, semi-structured interviews were conducted with experts in infrastructure and BIM management, whose insights supported the applicability of the methodology, highlighting its potential to improve data traceability, optimize resources, and strengthen preventive risk management. The findings confirm that the BIM methodology constitutes an effective tool for the integrated management of road infrastructure projects, especially in contexts with limited technical and financial resources. Its implementation fosters interoperability among stakeholders, informed decision-making, and the sustainability of public investments. In conclusion, the application of BIM in rural tertiary roads represents a significant contribution to improving efficiency, transparency, and strategic planning in Colombia’s road infrastructure sector.Tipo de ítem: Ítem , Análisis de la Utilidad de la Inteligencia Artificial para Identificar Daños en la Infraestructura Vial en el Contexto Colombiano(Universidad Santo Tomás, 0017-07-20) Alvarado Carvajal, Sara Inés; González Camargo, Carlos Alberto; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000628824; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001670007; https://orcid.org/0000-0003-1305-0966; https://orcid.org/0000-0002-5101-4950This thesis examines the use of artificial intelligence (AI) for damage detection in road infrastructure in Colombia, with the aim of evaluating the effectiveness of AI in the maintenance and management of the country's roads. To achieve this, methods such as literature review, analysis of the Colombian context, comparison of global findings, and cost-benefit analysis with specific strategic recommendations were employed. The results revealed that AI, particularly through neural networks and computer vision technologies, can significantly improve the accuracy and efficiency of damage identification in pavements, overcoming the limitations of traditional methods such as visual inspections. These findings are significant because they indicate that the implementation of AI could transform road management in Colombia, optimizing resources, reducing operational costs, and improving road safety. Finally, it is concluded that the integration of AI in road interventions is feasible and highly promising, especially in the early detection of damage and the optimization of resource allocation. These results have implications for public policy formulation and road infrastructure maintenance in Colombia, highlighting the need for training and technological adaptation, as well as a suitable regulatory framework to ensure the success of this implementation.Tipo de ítem: Ítem , Impacto del Cambio Climático en la Infraestructura del Transporte por Carretera : una Revisión Sistemática de las Medidas de Adaptación(Universidad Santo Tomás, 2025) Vargas Morales, José Eduardo; González Camargo, Carlos Alberto; Carmona Álvarez, July Estefany; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000628824; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000079395; https://scholar.google.com/citations?hl=es&user=r6ByV0oAAAAJ; https://orcid.org/0000-0003-1305-0966; https://orcid.org/0000-0003-2212-3901The main objective of this paper was to describe strategic dynamics related to adaptation measures aimed at promoting sustainability and innovation in road transport infrastructure that allow it to address the impacts of climate threats.

The goal is to develop a more resistant and environmentally sustainable road solution compared to traditional mixtures. Initially, it was characterized using the extraction method INV E-732-13, obtaining asphalt contents of 10.7%, 10.8%, and 11.2%. Based on these results, mixtures were designed with different percentages of CRL emulsion (3% to 7%) and stone aggregates, adjusting the granulometric curve according to INVIAS specifications. The determination of the optimal emulsion content (6%) was carried out through the immersion-compression test (INV E-622-13), resulting in a preserved resistance of 76.03%, meeting the requirements of Table 442P-12 of the INVIAS specifications. Subsequently, different proportions of lime and cement were incorporated as stabilizers, evaluating their effect through the indirect tensile test (INV E-725-13) to analyze resistance to moisture. The mixture with 6% emulsion and 1.5% lime achieved the best results in terms of cohesion and compressive strength, meeting the required preserved resistance index according to current regulations. This research demonstrates that the combined addition of lime improves the mechanical resistance properties of the mixture under humid conditions. It concludes that this formulation represents a technical alternative for road infrastructure in areas where the exploitation of asphaltite is feasible, contributing to the sustainability of projects and the use of local materials.Tipo de ítem: Ítem , Metodología de Auditoría para la Implementación de la Metodología BIM en los Procesos de Obra Pública del IDU en Bogotá(Universidad Santo Tomás, 2024) Barón Ramírez, Ángel Alexis; Hernandez Martinez, Jherson Ferney; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001953317This document includes the analysis, evaluation and proposal for an audit methodology for the implementation of the BIM methodology in road infrastructure projects at the Urban Development Institute, to be shared from the analysis of the contractual documents (BIM IDU Annex V 5.0) until the implementation of this annex in a public works project, identifying opportunities for improvement and proposing a 4-phase audit methodology with its respective responsible parties and deliverables, up to its efficiency indicators.Tipo de ítem: Ítem , Modelación y Análisis Técnico del Comportamiento de los Vehículos de Carga, por Afectación a la Movilidad en Tramo de la Carrera 13, entre Calles 53 y 45, en La Ciudad de Bogotá(Universidad Santo Tomás, 2024) Alvarez Penagos, Juan José; Preziosi Ribero, Antonio; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001343312; https://scholar.google.com/citations?user=1H_kwPYAAAAJ&hl=es&oi=ao; https://orcid.org/0000-0002-0202-8870One of the most important roads in Bogota is the called Carrera 13, where is a wide variety of commerce and night recreation places.

Based on these analyzes and observations, both basic or minimal measures were proposed, as well as other not so conventional ones, where the concept of self-explanatory roads was applied, making use of the new technologies that we currently have, and where evidence was presented that has been implemented in other countries and places where they have had good results in terms of improving road safety.Tipo de ítem: Ítem , Guía Metodológica para la Gestión de Riesgos en los Procesos de Inicio y Planeación en Proyectos de Infraestructura Vial(Universidad Santo Tomás, 2024-07) Vidal Ortiz, Maria Fernanda; Sierra Sánchez, Fayber Ricardo; García Quintero, Jesús David; Díaz López, Fabio Eduardo; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001912257; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000530328; https://scholar.google.es/citations?hl=es&user=yep-lzAAAAAJ; https://scholar.google.es/citations?hl=es&user=22jBnf4AAAAJ; https://orcid.org/0000-0003-0605-6630; https://orcid.org/0000-0001-8035-2775The research, focused on risk management in the planning of road infrastructure projects, specifically in the context of mass public transportation systems such as Transmilenio in Bogotá, has yielded significant conclusions. The initial objectives were comprehensively addressed, providing comprehensive methodological guidance for risk management in the initial stages of similar projects. The identification of intrinsic complexity in massive projects, evidenced in the analysis of Transmilenio trunk contracts, highlighting the need to manage technical complexity from the initial phases. The extended duration of contracts underlines the importance of initiative-taking risk management. The variation in contractual deadlines highlights the need to manage changes in project requirements to avoid negative impacts on schedules, highlighting adaptability as essential. The detailed analysis of seven critical aspects in Transmilenio trunk contracts reveals the importance of effectively managing project complexity, deadline extensions, changes in scope, feasibility evaluations, financial commitments, operating conditions, and execution times. The risk matrix developed provides a practical tool for the identification and mitigation of specific risks. Therefore, a methodology is proposed based on the guidelines of the PMBOK seventh edition (PMI, 2021), the standard for risk management in portfolios, programs and projects (PMI 2022), NTC 31010 (ICONTEC, 2019) and the guide for the risk management process in rapid renovation projects, Molenaar, et al (2014), this methodology for the accurate identification of risks during initial phases. This methodology, supported by detailed contract analysis, offers an applicable approach for effective risk management in road infrastructure projects.Tipo de ítem: Ítem , Análisis de la Gestión de Activos Operacionales para el Aprovechamiento Estratégico Infraestructuras Ferroviarias(Universidad Santo Tomás, 2024-09-20) Benavides Quintero, Holman David; Gonzáles Camargo, Carlos Alberto; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000628824; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001720097; https://orcid.org/0000-0003-1305-0966Railway asset management has gained special relevance in the last decade, due to the need to adopt long-term operational and maintenance strategies that ensure the sustainability, reliability, efficiency and safety of railway systems. The implementation of asset management under the ISO 55000 standard has proven its effectiveness in both private companies and public institutions. This standard has allowed for optimized management of infrastructures and services, facilitating more efficient planning. In this context, the objective of this work is to propose an analytical model for railway asset management based on indicators characteristic of strategic management in the planning of transport services, improving decision-making in infrastructures. This research highlights how the adoption of ISO 55001 and its application in the system and in the railway sector provide added value, optimizing data collection and the identification of periodic and routine processes characteristic of infrastructures. Furthermore, it allows a unique analysis through asset management activities, including maintenance, operation and service provision, presenting a crucial analysis for strategic and operational decision making for railway asset management. Thus, this research develops, based on the Risk Priority Index, a methodology for railway asset management, providing a proposal for a railway asset management model for the strategic management of railway infrastructures.
