highway design standards

Highway design standards are the guidelines used to plan and build roads that are safe, efficient, and suitable for traffic flow. They include specifications for lane width, curved and straight sections, clear sightlines, shoulder space, and safety features to accommodate different vehicle types and speeds. These standards ensure roads handle traffic comfortably, reduce accidents, and facilitate smooth movement for drivers and pedestrians. They are developed based on research, traffic data, and best practices to maintain consistent, reliable infrastructure across regions.
