Highway Design and Safety

Topography and Technical Drawing.

An expositive and inquisitive approach is used during the presentationof the different concepts in the Theoretical-Practical classes and several application exercises are discussed. The students carry out a practical group work, essentially of practical application of the studied subjects, which consists on defining the horizontal and vertical alignments of a small road, taking into account a set of typical conditions in these questions. In the Tutorial classes, a self-learning and communication methodology is followed, as well as the monitoring of students, by clarifying theoretical doubts, solving exercises and overseeing the progress of practical works .

Goals: It is intended that students grasp the main features and constraints of land transport infrastructures as Civil engineering works, focusing especially on its geometrical layout; Generic Skills: Use of knowledge and understanding; Conducting judgment and decision making; Communication; Self-learning; Specific Skills: Acquire knowledge and understanding skills in the field of activities related to the design of land transport infrastructures, in its various components, in particular roads; Know how to analyze the geometric definition of a road and its interdependence with aspects related to road safety.

1. Geometrical design – Definition of the geometric layout according to a wide set of criteria, addressing issues currently encountered in the determination of the geometrical characteristics in the design phase, highlighting points of contact between the highways and the railroads. The discussed topics include: planning and main elements of a land transportation infrastructure, fundamental constraints of its layout, general geometric definition, traffic analysis and prediction and evaluation of the performance of traffic flow of isolated facilities.
2. Introduction to road safety and road signs – The combination of driver-vehicle-highway factors in the context of accidents, the importance of quality principles, spatial and temporal consistency in a safe road environment and the detection of risk locations. General principles of vertical and horizontal signage and framework of the Road Signs and Signals Regulations in use.
3. Evaluation of the volumes of land to be moved concerning the definition of the earthworks to be carried out, as regards the construction of a road or railway infrastructure
