To give professional qualities and ability to understand theories and applications regarding the discipline of “Road traffic circulation techniques”and " Design of transport systems", for complex phenomenon, like giving support for a planning decision of an integrated transportation system; even evaluating economical and local aspects.
At the end of the course, the student will be able to clearly communicate the theoretical and practical concepts, necessary to engage complex problems; and they could autonomously develop studies and research activities on the field of road traffic circulation and design of transport systems.
Fundamental knowledge of mathematics, physics, mechanical engineering, automotive engineering, and statistics. The knowledges gained at the “Fundamentals of transports” course are essentials.
Module of "Traffic flow, theory and technique": Traffic flow on highways. Components of a highway. Characteristics traffic flow curves. Service Levels for Basic Items. Fundamental relationships. Typical issues.
Stop controlled intersections. Signalized intersections: minimum cycle and optimal cycle, phasing plans and signal timing with theoretical and experimental evaluation of average time lost. Level of service for signalized intersections. Projecting and verification problems. Fixed traffic signals and actuated traffic signals; types of actuated traffic signals. Signalized intersection coordination; green time optimization. Regulation for not signalized intersection: stop controlled intersection; roundabouts; level of services. Traffic flow management at intersections. The urban roads level of services: verification problems according with the HCM.
Design of Transportation Systems Module:
To study complex systems such as transportation systems requires analysis of the relationships between the different interacting system components. In particular, this course deals with the relationships between the internal components of the transportation system itself and their connections with the other external components.
SYSTEMS THINKING IN ENGINEERING (10h):
The systems approach– examples of application of a systems approach in designing complex transportation systems.
INTERNAL COMPONENTS (18 h):
Vehicle - Operating costs and user costs – The Management System - the management system: connection with other components – The Environment and Infrastructure– Comfort and Accessibility – Active safety - Biomechanical Models - Anthropometry – Psychophysical Models - Space Syntax.
EXTERNAL COMPONENTS (18 h):
Relationships between land use and transportation – Noise – Gas emissions – temperature, ventilation and lighting.
THE DECISION MAKING PROCESS (14h):
Introduction to Multicriteria Analysis - Multicriteria Analysis – Concordance Analysis – Brief introduction to Stated Preference - Fuzzy Logic – Brief introduction to Neural Networks.
The Module of Traffic flow, theory and technique,will be managed with 50 hours of classes, and it will be integrate with 10 hours of practice exercises.
The Design of Transportation Systems Module consists of a total of 60 hours. Traditional classroom lectures will be integrated with guided visits to major companies operating in the transportation systems and logistics sectors.
Verification of learning
The verification of the knowledge acquired in the two modules will be carried out through an oral exam.
Final oral exam. Final grade expressed in a scale of grades from 18/30 to 30/30.
