Fundamentals of vehicle dynamics. Elements of traffic engineering.

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course intends to provide all technical-scientific tools for planning a road infrastructure taking into account environmental issues as well. Through a classroom tutorial based on the use of specific software, students will acquire design skills of a road section.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The course will allow students to acquire methods and procedures for analyzing road infrastructure systems with the aim of planning and project execution. Theoretical and technical background will be acquired through classroom lectures and a tutorial which provides the use of a specific road design software.
TRANSVERSAL SKILLS:
The tutorial activities aimed at developing the road design project will help the student to improve own decision-making, judgment and interpersonal skills for managing projects related to Civil Engineering aspects on the basis of a multidisciplinary approach.

Program
Analysis of environmental and territorial planning charts; traditional and modern geometric design. Type road design, track analysis, minimum radius of curve, horizontal curves, design superelevation and widening on curves, vertical alignment of edges, design speed control chart; vertical alignment, vertical curves, climbing lane for heavy vehicles; typical cross sections, cross section elements: platform, roadway, traffic lane, traffic shoulder, roadsides. Preliminary, definite and executive plan. Metric calculation, costs analysis, works survey, specification of a contract. Preliminary environmental impact study: planning, design and environment; environmental impacts assessment and analysis, environment monitoring and mitigation. Road pavement design. Natural engineering techniques. Road traffic emissions. Road lighting. Road sign. Road safety: road restrains systems. Types, performance classes and design selection of safety barriers. Road design by means of a software: creation of numerical model for the ground, placing of the basic elements for the horizontal track, drawing out of the vertical profile of ground and placing of the gradients and vertical curves by design, drawing out of cross sections, placing of the road platform and calculation of volumes. Practice: road section design by means of a software.

Development of the examination
LEARNING EVALUATION METHODS
Oral exam after the approval of the design exercise.

LEARNING EVALUATION CRITERIA
The learning evaluation criteria consists of two examinations: - evaluation of the knowledge necessary for the preparation of the design exercise; - oral examination focus on some of the course topics. The design exercise can be carried out as a group work; each group consists of, at most, six students. A positive score in the first test (design exercise) is mandatory in order to access to the oral examination. In the case of a negative score in the oral examination, the student have to take again both tests. In order to pass positively the examination, the student needs to prove to have fully understood the course topics and to have learned the criteria and the procedures necessary for the geometric design of highways.

LEARNING MEASUREMENT CRITERIA
Assignment of a final score (maximum score is 30)

FINAL MARK ALLOCATION CRITERIA
In order to pass the examination with a minimum score, the student needs to know sufficiently each course topic. Higher score will be assigned based on the general and specific competences. The maximum score will be achieved by proving an extensive knowledge of the course topics during the examinations. The score “cum laude“ will be assigned to the student that will obtain the maximum score and will be able to prove a strong competence on the subject as well as to excel in the oral examination.
