Traffic Safety & Planning and Design of Roundabouts





Offered by

Civil Engineering




Main purpose

To provide students with knowledge and skills to evaluate traffic safety issues in existing and new designs and to prepare students to work with planning and design of roundabouts.


After completion of the course, the student must have the overall knowledge on key elements of roundabouts and use of these in an urban environment.


After completion of the course, the student must have the skills to plan and design the geometry of roundabouts in urban areas. Furthermore, the student must have the skills to evaluate and apply traffic safety measures in the project.
After the completion of the course, the student must:
  • Understand the characteristics and needs of the different road users in city and urban areas
  • Analyze and understand different situations and designs with the purpose of identifying potential traffic safety problems
  • Handle and document traffic safety issues in own designs and to come up with solutions and ideas on how to improve on existing designs


After completion of this course, the student must have the competences to:
  • Analyze the capacity in a roundabout
  • Propose relevant designs of roundabouts – horizontal and vertical geometry, as well as, cross sections
  • Use CAD software for design of roundabouts
  • Design traffic solutions where the characteristics of the different road users are incorporated
  • Evaluate drainage principles and carry out drainage controls in own design
  • Propose materials and pavements for a roundabout
  • Evaluate and plan traffic flow during construction works
  • Analyze traffic safety measures in new and existing designs
