ABSTRACT
In this project, Engineering Survey was conducted to help us determine the curve setting out of the UNIVERSITY OF BENIN MAIN GATE TO AUDITORIUM ROAD. Horizontal curves are an essential element in the geometric design of highways, providing a gradual transition between two tangent strips of roadway, allowing a vehicle to negotiate a turn at a gradual rate rather than a sharp cut. The design of the curve is dependent on the intended design speed for the roadway, as well as other factors including drainage and friction. There are several methods of setting out simple circular curves by linear methods and by the use of chain and tape, including offsets from the long chord, successive bisection of arcs, offsets from the tangents, and offsets from chords produced. The determination of the radius of curvature of the horizontal curve can be done by various methods, including the deflection angle method. This project focuses on the critical task of determining curve setting out parameters for Uniben road to Auditorium Road, a pivotal aspect of infrastructure development and transportation engineering. The accurate design and construction of road curves are fundamental to ensuring safe and efficient transportation networks. The project aims to investigate and establish a comprehensive methodology for determining these parameters, taking into consideration factors such as road type, terrain, traffic volume, and safety standards. By achieving precise curve setting out parameters, road engineers can enhance road safety, reduce construction costs, and improve overall transportation network performance. The research methodology involves a multi-faceted approach, incorporating advanced surveying techniques, geospatial data analysis, and computer-aided design (CAD) tools. Through an extensive review of existing literature and case studies, this project will develop a set of guidelines and recommendations for road curve design, encompassing horizontal and vertical alignments, superelevation, and sight distance requirements. Additionally, the study will explore the integration of modern technologies, such as Geographic Information Systems (GIS) and Global Positioning System (GPS), to streamline the process and improve accuracy. The outcome of this project will empower road planners and engineers to create safer, more efficient road systems that cater to the growing demands of contemporary transportation networks while optimizing resource utilization.
