PCI eLearning Course T510: Bridge Geometry-Working with Horizontal Alignments
Description
Locating points along or offset from a horizontal alignment is necessary to defining bridge geometry. This course presents a vector-based approach to locating the North and East coordinates of point defined by a horizontal alignment. The vector-based approach was taken as it closely follows the way CAD software is used. Vector solutions are presented for 1) Locating points on tangent runs and circular curves, 2) Locating points offset from tangent runs and circular curves, and 3) Project points onto a tangent run or circular curve.

In this course you will:

  • Identify a global coordinate system of coordinates
  • Locate North and East coordinates of points along a horizontal alignment
  • Locate North and East coordinates of points offset from a horizontal alignment
  • Project points with a known North and East coordinate onto a horizontal alignment
  • Develop offset parallel alignments
