Designing vertical curves in layout profiles requires that you understand the concepts described in this topic. To access the vertical curve creation commands, click the arrow next to the curve creation command displayed on the toolbar. After clicking a button on the Profile Layout Tools toolbar, follow the command prompts on the command line. You can use transparent commands to specify a station and elevation when you are prompted to select a point.
Quadratic parabolas are preferred in vertical designs as they have a constant rate of change of grade along the curve. Quadratic parabolas are a very close approximation to circular curves at flat grades and are usually used in vertical design. This quality makes them very easy to stake out. Substituting these values we get the quadratic parabola equation for vertical curve as:.
Since the rate of grade change is constant over the length of the curve, the parabolic curve parameter can be expressed as:. It expresses the abruptness of the grade change in a single value. Speed tables or other design tools often provide a target minimum K value.
The criteria-based design feature automatically validates profile curve design against local design standards. Curves that violate your design standards can be corrected by using the Profile Layout Parameters dialog box to either adjust K value directly, or change curve length and tangent grade to meet the criteria.
This design method for crest curves provides a minimum curve length. The curve must be long enough so that the driver of a standard vehicle can always see an object before it gets within the maximum stopping distance for the designed speed of travel. The curve must be long enough so that the driver of a standard vehicle can always see an oncoming vehicle within a safe distance for the designed speed of travel.
This design method for sag curves provides a minimum curve length. The curve must be long enough so that in dark driving conditions, the headlights of a standard vehicle illuminate the road a safe distance beyond the stopping distance for the designed speed of travel. The curve must be long enough so that people in a standard vehicle do not experience excessive inertial force as they travel through the curve at the designed speed. Curve Types Taylor Pohlman Parabolic.
Most vertical curves in road design are symmetrical parabolic curves for a good reason. The parabolic curve is the natural vertical curve followed by any projectile. A properly designed symmetrical parabola minimizes the inertial forces on a vehicle traveling along the curve.
Highway curves are often designed with reference to curve tables, such as those provided by the American Association of State Highway and Transportation Officials A. These tables can be used only with symmetrical parabolic curves. K-value formula. Stopping Sight Distance This design method for crest curves provides a minimum curve length.
