Recommended Prerequisites

Basic concepts of Spatial Planning, Topography and Technical Drawing.

Teaching Methods

Theoretical presentations of basic principles and theories relating to the different topics, using audiovisual tools complemented by practical exercises resolution when adequate.

Students are also required to solve real life problems with only limited tutorial support, with most of the work to be carried out in group work during practical classes. This enables the consolidation of concepts and the understanding of how the analysis of real life problems and the search for adequate solutions implies the integrated use of different design rules and models.

Learning Outcomes

The course makes a basic but comprehensive introduction to Highway and Traffic Engineering, enabling the student to acquire the concepts and tools needed to solve standard problems.

He should be able to apply simplified demand models and then design the basic highway infrastructure elements.

Specifically, he should gain the competences enabling him to estimate the capacity and level of service of normal stretches of roads and the most common types of intersections, as well as to design their geometric characteristics.
