The horizontal curves used in road and rail transport systems form critical parts of the route. One important topic to focus on increasing comfort and ensuring safety throughout the route is the determination of the minimum curved semiconductor. In the design phase of the horizontal geometry of a route, small semiconductors than the smallest predetermined curve squares cannot be used. Therefore, the minimum curve semiconductor is one of the most important limit values to be considered in the design. This value can be calculated depending on the debt limit values, the side drive limit values, the view lengths and the side simplicity limit values. In this study, the sadness comfort measure was used to calculate the minimum curve halfway in the design phase of the route geometry. Then, the calculated values were compared with the values calculated according to other criteria to determine the most appropriate curve semiconductor for road and vehicle dynamics to ensure comfortable and secure transportation. According to the results of comparisons on different speeds, shapes and graphics, the best standards available for different project speeds were determined and the horizontal curve values calculated for these standards were recommended.
