Station equation

A station equation refers to the phenomenon that the stake number is not continued due to stationing changes or section measurement.

Alignment

The horizontal alignment is a curve that describes the turning and trend of the road curve in the horizontal plane. It generally consists of straight lines, arcs, and transition curves. The transition curve used in the calculation of the software is the clothoid (also known as Cornu spiral or Euler spiral) commonly used in road design.

+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | | | | | | | Figure 2.89[]{#_Toc30691 .anchor} Intersection method interface | Figure 2.90[]{#_Toc24744 .anchor} Element method interface | +-----------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------+

Alignment - Intersection method

The intersection method is based on the intersection point in the alignment, and the coordinates are obtained through the intersection point and the route. The general intersection point method to construct an alignment consists of a starting polyline point, N intersection points and an ending polyline point. Enter the coordinates of the designed road at the starting and ending polyline points; the intersection needs to enter the coordinates of the designed intersection point, the length of the entry transition curve, the radius and the length of the exit transition curve. The software will automatically calculate the elements contained under the intersection and draw the road alignment.

The current software supports the conversion calculation from the intersection method to the element method; supports the input of the intersection method of the complete symmetric transition curve and the complete asymmetric transition curve; supports the intersection method input when the transition curve length is 0 or the arc length is 0; it does not support the input of incomplete transition curve; it does not support the intersection method input of special curve such as a turning curve.

Alignment - Element method

The element method is a method to calculate the alignment coordinates from the node elements such as the starting point coordinates, azimuth angle, starting point stake number and ending point stake number of the road. Select the corresponding elements when entering the element method, including straight lines, left-turning arcs, right-turning arcs, left-turning transition curves, right-turning transition curves, and then input the corresponding feature parameters of the elements, such as the length, start radius and end radius of the transition curve. The software will draw a road alignment according to the input line elements.

Vertical Profile

A vertical profile refers to the curve that connects two adjacent wavebands on the vertical section of the line with the slope point as the intersection point. The vertical profile describes the change of the elevation coordinate of the middle stake point. The vertical profile in the software is calculated using a parabola.

Cross Section

The cross section refers to the section perpendicular to the center line of the road at the center pile. The main components include motor vehicle lanes, non-motor vehicle lanes, sidewalks, hard shoulders, soil shoulders, central separation belts, and side partitions.

The cross section need to be established on the vertical profile.

The super-elevation and widening properties in the software need to be established on the basis of the standard cross section.

Super Elevation

When a vehicle is driving on a curve, it will slip due to lateral force or centrifugal force. In order to offset the centrifugal force generated by the vehicle driving on the curve and ensure that the vehicle passes the curve safely and stably, a unidirectional cross-slope that is higher on the outside than the inside will be set on the cross section of the curved road section, which is the super-elevation property of the road. The superelevation of the road in the software is based on the standard cross-section, which will be reflected in the changes in the slope of the plates composed of different cross-sections, and will ultimately affect the change of the elevation coordinates of the side piles.

Widening

When the vehicle is driving on a curve, the driving trajectory of each wheel is different. The radius of the driving trajectory of the rear wheel on the inner side of the curve is the smallest, and the radius of the driving trajectory of the front wheel near the outer side of the curve is the largest. This phenomenon is more prominent when the radius of the driving curve is small. In order to ensure that the car does not encroach on the adjacent lanes when turning, the curved road sections need to be widened. The widening of the road in the software will be based on the standard cross-section, which will be reflected in the changes in the width of the plates composed of different cross-sections, and will ultimately affect the change of the side pile coordinates.

After the road parameters input is completed, use [Pile Point Detail] and [Preview] to check and confirm the road data.
