The field of geometric design of highways plays a pivotal role in shaping the physical and visible attributes of road infrastructure. This encompasses various elements such as cross-sectional features, sight distances, alignment, curves, and super elevation, all of which contribute to the overall functionality of the road network. With India experiencing a continuous rise in population, there is a corresponding surge in traffic volume. However, the allocation of funds from the government for the development of transportation infrastructure has not been entirely satisfactory. In light of these challenges, it becomes imperative to proactively plan and design the geometric elements of roads during the initial alignment phase, taking into account the anticipated growth in traffic. The consequences of neglecting this crucial aspect become apparent post-construction, making it not only difficult but also economically unfavorable to modify geometric elements. This can result in unwanted capital investments. This paper aims to provide a comprehensive review of past research efforts in the realm of highway geometric design, with a specific focus on emphasizing the importance of meticulous planning and designing of these geometric features. While there exist numerous factors influencing highway design, this study underscores the significance of adopting a suitable geometric design that aligns with the objective of achieving optimum efficiency in traffic operation, ensuring contentment and safety measures, all at a reasonable cost.
