B8640 - ROAD AND TRANSPORTATION ENGINEERING DESIGN PROJECTS

Learning outcomes

Students attending the course will develop the design of a road infrastructure, acquiring knowledge about the specific design standards and procedures. In particular the course will focus on the construction of a roundabout instead of an intersection in a real urban context. The student will obtain the skills necessary to design a roundabout in terms of pavement design, geometry and road signs. Interaction and collaboration between students will be fostered through the group work on the project.

Course contents

Upon completion of the course credits, students possess the skills necessary to design a roundabout. They are able to independently design the pavement, geometry, and signage.
In particular: 

• Introduction to the Case Study
• Road Materials
• Calculation of Traffic ESAs
• Use of Pavement Calculation Software
• Fatigue Checks of the Superstructure
• Geometry of a Roundabout
• Calculation of Roundabout Capacity
• Calculation of Sight Distances
• Road Markings
