This includes traffic flow modelling, queuing theory, and optimization algorithms to assess traffic congestion, travel times, and transportation capacity. Mathematical modelling guides the design of roads, highways, railways, and transit systems, improving mobility, safety, and efficiency in urban and rural areas.
In Structural Design and Optimization
Mathematics is utilized in structural design to optimize the size, shape, and configuration of structural elements. Optimization techniques, including linear programming and finite element analysis, are applied to minimize material usage, reduce costs, and enhance structural performance. Mathematical modelling helps engineers explore alternative design solutions, considering factors such as load distribution, material properties, and environmental conditions.
In Surveying and Geomatics
Mathematics plays a crucial role in surveying and geomatics, providing the foundation for measuring and mapping the Earth’s surface. Trigonometry, geometry, and coordinate systems are used to determine distances, angles, and elevations in land surveying. Mathematical algorithms guide the processing of satellite imagery, LiDAR data, and geographic information systems (GIS), supporting applications such as land development, urban planning, and environmental monitoring.
