Road design

Acquisition of necessary theoretical and practical knowledge in the field of design of suburban roads. Road design is studied from the point of view of traffic, spatial, driving-dynamic, geometric, aesthetic, economic and ecological aspects, with detailed acquaintance with the design methodology, with the aim of determining the optimal solution of the road route.

Mastering the program contents of the subject enables students to participate in a complex process in which numerous theoretical and experiential knowledge are intertwined. In this complex job, after completing the program, the student is able to provide functionality through the construction of the facility and timely consider the economic, spatial, environmental and other consequences.
