Objectives
It is intended that the students obtain the necessary knowledge to the planning, conception and design of transportation infrastructures, especially road infrastructures, with focus on geometric design but also considering the basic concepts of earthworks, drainage, paving and safety equipment.
Prerequisites
Basic knowledge on surveying.
Subject matter
1. Transport and transportation infrastructures. Comparison between railway, road and airport transportation.
2. Road planning.
3. Phases for design. Project components.
4. Restrictions for the conception of transportation infrastructures.
5. Driving conditions. Level-of-service and road capacity. Definition of speed and sight distances.
6. Horizontal alignment and vertical alignment. Restrictions to geometric design.
7. Cross-section elements.
8. Crossing. Types and characteristics.
9. Basic elements for earthworks, drainage, pavements and safety equipment.

Teaching method
In parallel to the lectures on transportation infrastructures and the expositions on exercises concerning geometric design, students work in group to conceive a road section project, which includes geometric design, earthworks, drainage, paving and safety equipment. The evaluation comprises the elements prepared for the group project, the attendance of lectures and practical sessions and a final exam.
Evaluation method
The evaluation includes two components: theoretical-pratical (60%); project (40%).
The theoretical-pratical component includes 2 written tests during the semester with equal proportion (50 %).
The project is prepared in group with a maximum of three students.
Approval requires attendance to at least 2/3 of lectures and 2/3 of practical classes, a project grade higher than 9.5/20, an average grade in tests higher than 9/20 and a minimum final grade of 9,5/20.
Students which attended classes and did the project, in shcool year 2015/2016, are dismissed of attending pratical classes and doing the road project work.
