Other auxiliary systems. 7. Control and management of transportation systems: o Control and management of transportation. o Road, rail, air and maritime traffic. International transport modes.
Learning activities and methodology
The educational methodology includes: 1) Lectures covering the main topics of the course. In order to facilitate the learning process the students will receive support material and information to let them complete and focus on the relevant topics or interesting topics for them. 2) Resolution of problems, related to the knowledge that must be acquired and above all related to the specific competences the student must develop. 3) Resolution of exercises that will allow the student to consolidate the knowledge and contrast the results with the reality. This will develop the capacity of self-evaluation and the students will acquire skills and develop technical creativity. 4) Reports elaboration. Sharing of solutions obtained by the students to answer problems in engineering and their participative correction should serve to improve their understanding of the course contents and to develop the students' ability to assess and communicate relevant information for the problem solution. Besides, this sharing of information will promote the exchange of critical (analytical) opinions between the instructor and the students or amongst the students.
