A significant number of fatalities along horizontal curves of rural highways necessitated the safety evaluation in the curve design. Previous studies explored safety evaluation based on several approaches such as operating speed, driver workload, alignment index, and vehicle stability. However, researchers predominantly focused on vehicle speed because it has a close resemblance to design speed and straightforward implementation in the field. The safety evaluation criteria for horizontal curves are majorly speed-based studies. Hence, this chapter represents several operating speed-based safety evaluation approaches available in the literature. It provides insight on the requirement of holistic design guidelines and appropriate safety performance measures to develop safer geometric elements for low-middle income countries like India.
