Abstract :Highway geometry plays an important role in road safety and mobility. A successful or unsuccessful geometric design result directly or indirectly affects the driver, the physical implementation of the design. Therefore, roads should be designed with the driver in mind. Virtual reality programs play an important role in helping road engineers design and evaluate alternative road configurations. Virtual reality programs play an important role in evaluating the geometric design security of roads, intersections of roads and intersections and taking precautions against problematic geometric elements. In this study, the importance of geometric standards in existing highways is confirmed by using Virtual CRASH4, a virtual reality program. In this context, three highways with different design criteria were designed using Virtual CRASH4. Accident risks arising from speed changes and design errors have been identified on the designed roads.
