Highway Engineering II (Traffic Engineering)

Compulsory subject of major direction of Transportation Engineering - 7th semester. The aim of the course is the acquisition of general traffic technical knowledge. This knowledge is necessary for the understanding of traffic engineering concepts and the subsequent investigation, proposal and evaluation of urban traffic regulations (nodes with traffic lights) and interurban roads (interurban roads two or more lanes and motorways). More specifically, the course initially focuses on the concepts and basic relationships of traffic figures. Then methods for traffic study and the estimation / calculation of operational standards signalized junctions and road sections and traffic simulation models are presented. Beyond the presentations of individual modules, in this course a visit takes place in the Traffic Management Center of Law Attica (which belongs to Attica) through which the usefulness and application of the knowledge acquired in the operation of the center is suggested. The course is taught in the School of Rural and Surveying Engineering in National Technical University of Athens.
