The document discusses several topics related to road design and traffic safety:
1) It analyzes the need for road safety audits and reviews for new road projects and major reconstructions, and argues they should be mandatory to help engineers incorporate modern safety concepts.
2) It proposes defining "autovias" (limited-access highways in Argentina) and establishing design criteria for access control, connections to collector roads, and progressive improvements to meet autopista standards over time.
3) It analyzes the appropriate width for median barriers on divided highways, arguing narrow medians are sufficient for safety while wider medians proposed in Argentina have failed due to excessive costs and issues accommodating road elements.
This document summarizes the results of a project in Germany that aimed to determine road and traffic variables that influence overtaking maneuvers and related crashes. An analysis of crash data from five German states identified 500 rural road sections most prone to overtaking crashes. Factors found to influence overtaking crashes included road design (curves, sight distances), traffic regulations (overtaking restrictions, speed limits), and driver behavior (misjudging gaps). Recommendations are made to prevent overtaking crashes through infrastructure improvements and traffic measures that improve sight distances and driver awareness of hazards.
This document discusses several proposals and countermeasures to improve road safety in Argentina. It includes 6 topics for discussion: 1) Professional training for road safety engineers and road safety audits, 2) Relationship between geometric design standards and road safety - mathematical models, 3) Definitions of highway, semi-highway, motorway regarding number of lanes, 4) Median width for divided roadways, 5) International evolution of single-lane roundabouts, and 6) Safer roads according to predominant or exclusive vehicle types. The document is a draft for discussion and debate, presenting personal opinions of the authors. It provides background on road safety audits and reviews in Argentina and proposes making them mandatory for new projects or major road reconstructions.
This document presents a study of different bypass route solutions around the towns of Alcantara de Jucar, Cárcer and Cotes in Valencia Province, Spain. Four alternative routes were proposed and evaluated based on multi-criteria analyses of economic, road safety, and environmental impact factors. The analyses considered attributes like earthworks, expropriations, structures required, road length, visibility, access points, connections to other roads, impact on protected land and livestock routes, proximity to buildings and developable land, flood risk, and expected service level. The recommended solution adopted for further development as a basic project was the alternative route determined to have the lowest overall score across the factor and attribute evaluations.
This document discusses solutions for improving roadside safety related to utility poles. It begins by providing context on the safety issues posed by utility poles located near roads. It then describes three categories of solutions: 1) keeping vehicles on the roadway through measures like pavement markings and wider shoulders; 2) relocating or removing poles by increasing setbacks, combining utilities on shared poles, or burying lines; and 3) using safety devices like breakaway poles, guardrails, or concrete barriers. The document emphasizes that the optimal design uses as few poles as practical in low-risk locations. It also notes that while removing poles would eliminate crashes, the cost is a major consideration.
The document discusses efficient solutions for traffic systems, focusing on applications for roads. It describes how SICK solutions are used for (1) monitoring electronic toll collection through 3D laser scanning and automation light grids to classify vehicles, (2) red light and speed monitoring using laser-based sensors, and (3) ensuring traffic safety with solutions for clearance measurement, hot spot detection, and more.

This case study investigates a situation at the University of Florida regarding the impacts of a new parking structure on Museum Road in Gainesville, Florida. The increased traffic to and from the new structure would access this facility via a two-way stop-controlled intersection, but alternatives are being analyzed to determine the best solution for this and adjacent intersections along Museum Road. Pedestrian, bicycle, and transit-related activities are high within this section of Museum Road, and so the solution must be sensitive to and consider all travel modes.
This document summarizes a seminar presentation about roundabouts. The presentation discussed why roundabouts are safer than traditional intersections with traffic signals or stop signs, providing statistics showing large reductions in crashes and injuries at roundabouts. It covered design elements of modern roundabouts that contribute to safety, such as deflection and low entry speeds. The presentation also addressed concerns about pedestrian, bicyclist, and visually impaired accessibility at roundabouts and showed how well-designed roundabouts can improve safety and traffic flow for all users. A brief history of roundabout development in various countries was presented as well.

This document presents the analysis of improving the intersection of State Route 96 and X Street. It contains existing conditions of the intersection including traffic volumes and level of service. Two alternatives are analyzed to improve the level of service for the projected 2033 traffic volumes. Alternative 1 adds additional lanes to each approach. Alternative 2 changes the signal phasing to group approaches differently. Both alternatives are able to achieve acceptable levels of service through 2033 based on the analysis in the tables provided. Vertical and horizontal geometric designs as well as pavement design are also discussed to accommodate the projected traffic.
This document summarizes a presentation on dynamic lane guidance. It discusses using intelligent transport systems for cooperation and automation through tactical driving advice provided to vehicles. This could involve providing speed, headway and lane use advice to vehicles based on real-time traffic state estimation integrating data from vehicles, roadside infrastructure and traffic management centers. The presentation examines requirements and challenges for achieving lane-level positioning accuracy needed for such advice, and shows simulation results of dynamic lane guidance systems reducing travel time delays on highways by influencing traffic flow dynamics.
Intersection CONCEPTUAL DESIGN Methodology, by Grant Johnson PE PTOEGrant Johnson, PE
It starts with analysis. Synchro Pro. Then a common sense approach to building an intersection design that follows analysis. First learn the traffic patterns, and then maximize flow rates and capacity by designing smart. Not smart growth, but smart design based on common sense and putting resources like lanes and signal timing where it is most needed, eliminating waste in design. True problem solving.
Diagnostic load testing of bridges - case studies Eva Lantsoght
This document summarizes diagnostic load testing performed on two new bridges in Ecuador: the Los Pajaros Bridge and ramps at the La Armenia Interchange. Load testing involved placing trucks weighing up to 2400kN (60% of design load) in various positions to model different load cases. Deflections were measured and compared to computational models. For both bridges, measured deflections closely matched predictions, validating the bridge designs and indicating they were ready for traffic. In conclusion, diagnostic load testing is an important way to verify bridge designs by comparing real responses to models.
The document summarizes a student presentation about converting a disused railway into a greenway in London, UK. It describes exploring two potential sites before selecting the Belmont Trail for its development potential and support. The project involved designing the greenway's geometry, pavement, and a community center using CAD software. Design considerations included grades, curves, sight lines, drainage and ADA accessibility. The presentation covered the existing conditions, design process, proposed site plans and some building details.

A traffic engineering firm conducted a capacity review of a proposed single lane roundabout at the intersection of SR 28 and Coon Street in Kings Beach, California using 2008 traffic volumes. Their analysis using RODEL software found that at a 50th percentile confidence level, the roundabout would operate at Level of Service C, but at an 85th percentile confidence level, which accounts for urban factors, it would operate at Level of Service F with significant delays. They determined that a single lane roundabout would not have adequate capacity based on the 2008 traffic volumes and urban conditions at this intersection.
Forum presentation #4 innovative signal control at mlk cve5022 c-5110c_finNathan Baker
The document summarizes a presentation on innovative signal control for an intersection in Uptown Cincinnati. It analyzed the existing traffic conditions and performance of the pre-timed signal control, which was found to have long delays. An alternative with actuated signal control and geometric changes was modeled and found to improve traffic flow. An adaptive traffic signal control system was also proposed, which uses algorithms to adjust signal timing in response to real-time traffic conditions. Modeling showed this approach could reduce delays and increase speeds compared to the existing control system. The presentation concluded with recommendations to further optimize the adaptive system and evaluate impacts and costs of implementation.
The document discusses roadside design and clear zone concepts. It defines clear zone as the total roadside area available for safe use by errant vehicles. It emphasizes removing hazards from the clear zone where possible, and using guardrails to protect from fixed objects that cannot be removed. Key factors in determining clear zone width include design speed, traffic volume, and slope geometry. The document also discusses treatments for hazardous areas such as removing, relocating, breaking the fall of, or delineating hazards. It provides guidance on proper use, length, and installation of guardrails to reduce impact severity from hazards that cannot be removed from the clear zone.
The document proposes updates to the subdivision code regarding street widths and the review process. It suggests establishing two standard street designs - a narrow section with 28 feet of pavement and a wide section with 36 feet. It also proposes a three-tiered review process where minor variations would only require administrative approval while more significant changes would require a waiver reviewed by the Planning Commission. The goal is to introduce more flexibility for applicants while simplifying the review process.

Title: Level of Service F for Grade A Streets
Track: Prosper
Format: 90 minute panel
Abstract: Relying solely on Level of Service criteria for street design, which evaluates vehicle congestion, leads to poor outcomes on many of our roadways. LOS F, far from a failure, creates opportunities to reallocate roadway space for more livable street designs. In this session, learn about projects in Cambridge and San Francisco that overcame opposition and generated community support in prioritizing better bicycling and walking over vehicle capacity during the peak hour of travel.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

Redefining brain tumor segmentation: a cutting-edge convolutional neural netw...IJECEIAES
Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

ASV/RSV INTERNAS Y EXTERNAS OBLIGATORIAS Y SIMULTÁNEAS

La necesidad de Auditorias de Seguridad Vial y Revisiones de Seguridad Vial son un demérito para
el proyectista, quizás un ingeniero experimentado, recibido cuando todavía no se conocían los
hallazgos de Stonex, Leisch, Glennon, Hauer, sobre zona despejada, peligrosidad de los
dispositivos de contención y redirección, o los errores de conducción inducidos por los defectos del
camino. Ignora lo que no le enseñaron y con sus conocimientos de geometría analítica, análisis
matemático, y topografía se dedicó a diseñar caminos.
Al difundirse los novedosos conocimientos de SV, los ingenieros más estudiosos se actualizaron
con lecturas, cursos, congresos, y progresaron en su profesión. Otros se retrasaron y entonces
surgieron las auditorías de SV para ayudar a quienes principalmente creían que un trazado era
excelente si la poligonal cerraba, o el Brückner compensaba.

ASV/RSV INTERNAS Y EXTERNAS OBLIGATORIAS Y SIMULTÁNEAS

Con una actualización de los programas de diseño vial, con el acento en la SV, la profesión de
auditor no existiría. Es como si un médico después de recibido tuviera que pedir ayuda a la
enfermera para que le enseñe a tomar la presión o aplicar una inyección; lo cual ignoraría si no se lo
enseñaron. Además, si dos o tres de sus proyectos son sometidos a auditorías, a la cuarta ya
debería haber asimilado todo los conceptos de SV, y aplicarlos.
Para acelerar la difusión de los conocimientos de SV mientras se actualizan los programas
universitarios de grado y posgrado, este trabajo propone que las ASV y RSV sean OBLIGATORIAS
PARA CADA PROYECTO NUEVO O GRAN RECONSTRUCCIÓN DE CAMINO EXISTENTE, por
parte de un auditor calificado e INDEPENDIENTE, lo cual sería una auditoría externa, de un
proyecto que debió además ser internamente auto auditado por el proyectista, que para ser tal
debería tener título habilitante como el del auditor externo.
5. La velocidad directriz guía el diseño de los alineamientos horizontal y vertical según los principios
físicos de equilibrio dinámico de un vehículo en movimiento curvo, y distancia visual de detención en
curvas verticales, según modelos matemáticos racionales cuyos coeficientes se ajustan según
resultados y observaciones de experiencias de campo que los investigadores realizan con
actualizadas herramientas de medición de velocidad, desaceleración, distancia de frenado, fricción
neumático-calzada, peralte, inclinación lateral del vehículo, medidas con riguroso control.
Para una dada velocidad directriz, teniendo en cuenta adecuados coeficientes de seguridad, en
curvas horizontales, teóricamente el equilibrio dinámico se alcanza para una amplia gama de
combinaciones de valores prácticos de radios, peraltes y fricciones.
Para analizar las variables Velocidad, Radio, Peralte, Fricción Transversal y Longitud de transición, y
entender mejor cómo se relacionan, se plantearon cuatro monografías conexas y complementarias:

3 BENEFICIOS PREVISTOS
Seguridad Vial: al separar el tránsito liviano del pesado, en particular de los puntos negros de concentración de
accidentes mortales según datos provistos por el OCCOVI en el 2012, se reducirán los choques, y las congestiones
en el peligroso paso urbano por Campana – Zárate entre km 60 y 90.
Tiempo de viaje: desde y hasta Estación Panamericana, sustancialmente menor, por menor distancia de recorrido.
4 OPORTUNIDAD
El creciente desarrollo urbano entre Río Luján y RN193 hacia el sudoeste hará cada vez más difícil o imposible
encontrar una franja relativamente favorable como para no afectar valiosas propiedades.
