The Widening feature is a critical functionality within our software designed to assist engineers in precisely calculating and defining the lateral widening of roads. This feature, with its flexible rules and operations, empowers users to dynamically control the width of roads at different locations to meet diverse engineering requirements.

Key Features:

  1. Plate Division: This feature supports the division of roads into distinct plates, enabling users to finely manage and control the lateral widening changes.
  2. Flexibility in Change Points: Users can define change points, adjusting the starting and ending positions of widening as needed, ensuring calculation accuracy.
  3. Gradient Modes: Between two change points, the system can calculate lateral widening changes based on the user-defined gradient mode, ensuring a smooth transition in width within the change interval.

Calculation rules

The widening calculation rules are as follows:

During program computation, the process begins by determining the relevant section. Subsequently, the program systematically compares the station numbers to be calculated with the station numbers of the section, considering the following scenarios:

  1. No corresponding data for the widening in the section: The standard width of the standard cross-section for that section is adopted.
  2. Before the first change point station: The width of the first change point is adopted.
  3. After the last change point station: The width of the last change point is adopted.
  4. Between two change points: Based on the mileage and the widths of the two change points, the required width is calculated according to the gradient mode defined by the previous change point.

Import

If there are numerous widening parameters, you can access the corresponding route on the Surveyor Web version (https://cloud.bingce.com, copy and paste into your browser).

Navigate to the Widening page, choose the relevant section, and batch paste or import the widening parameter file. The imported file format should be in Excel (.xls/.xlsx), with data structured as follows:

1, Widening change point station, width, widening gradient mode (Linear 1, Cubic Parabola 3, Quartic Parabola 4)

1, Widening change point station, width, widening gradient mode (Linear 1, Cubic Parabola 3, Quartic Parabola 4)
