RoadDesignerSmart

RoadDesignerSmart helps you safe and smooth roads, clear tools. You can find stopping and overtaking sight distance, and check the minimum curve radius for any speed. It lets you work out superelevation, road grade, and vertical curve length for both crest and sag curves. You can also check safe speed on curves based on radius and superelevation. The app helps you set transition curve length for spiral curves in a quick way. It suggests lane width and shoulder width based on road class and speed. You can also design crossfall and camber so rainwater drains off the road safely.
