Description This is an introductory subject covering the design of dimensions and configurations of the visible features of a roadway. It will provide students with an understanding of pavement widths, horizontal and vertical alignment, slopes channelization, intersections and other features that can significantly affect the operations, safety, and capacity of the roadway network. This subject is designed in collaboration with Transport for NSW.

Learning Outcomes

  1. Explain highway terminology and concepts of geometric design of roads.
  2. Evaluate the various social, technical and environmental aspects involved with road geometry design.
  3. Analyse the factors influencing geometric roads design and link these to safety.
  4. Perform basic calculations related to road geometry design and traffic flow.  
  5. Explain the methods of design including horizontal and vertical alignment design and design of cross-sections as well as earthwork volume calculations.

Subject Content

  1. Introduction
  2. Fundamental Considerations
  3. Speed Parameters
  4. Cross-section
  5. Sight Distance
  6. Horizontal Alignment
  7. Vertical Alignment
  8. Coordination of Horizontal and Vertical Alignment

  10. Bridge Considerations

Design parameters include: road classification; design speeds; design vehicles; alignment controls; cross-section components, including travel lanes, shoulders and verges; and provisions for public transport and cyclists.

Speed parameters include: operating speed, desired speed and design speed; and their relationship with each other.

Horizontal and vertical alignments (include development and application of: circular curves; superelevation; grades; vertical curves; procedures for the grading of a road alignment; and determination of sight distances across vertical curves.
