Description
Objectives
1. To provide students with the fundamental knowledge of vehicle and pedestrian flow theory and calculation and modeling techniques of road traffic engineering. 2. To teach the macroscopic calculation procedures of capacity and level of service (performance) of interurban and urban roads (including for cycling and pedestrian networks) 3. To introduce students to microscopic modeling of urban traffic and use of microsimulation software 4. Provide students with the fundamentals of road safety
Syllabus
Module A - ETR Fundamentals i. Basic concepts ii. Observing, recording and representing traffic systems iii. Fundamental relationships of ETR and traffic currents iv. Queues and disturbance propagation Module B - Capacity and Levels of Service (NS) of the main elements of the interurban road network i. Concepts and performance factors ii. Two-way roads iii. Highways (current section, intersection, junctions) Module C - Capacity and NS of the main elements of urban road networks i. Concepts and Performance Factors of streets, cycle tracks and pedestrian spaces ii. Capacity and NS of priority intersections and traffic circles iii. Planning, capacity and NS of signalized intersections iv. Coordination of signal lights Module D - Introduction to microscopic modeling i. Lane-change, gap-acceptance, car-following models ii. Construction of simple simulation models Module E - Road Safety Fundamentals
Prerequisites
For admitted students to the Master of Science of Transportation Systems, there are no additional requirements. For other students, a completed bachelor's degree in any engineering course at IST, or urban planning, geography, economics, with at least 24 ECTS in mathematics, physics, statistics and/or computer science.
Cross Competence Component
The UC allows the development of soft skills in Critical Thinking, namely strategic thinking and problem-solving approaches, during the project development; and Interpersonal and intrapersonal skills (oral, organizational and team work, self-discipline, perseverance, self-motivation) also during the project development. The assessment percentage associated with these competences should be around 20%.
Laboratorial Component
ETR will have a computer laboratory component in which students will have an introduction to the microsimulation of road traffic, through the application to practical cases of intersections or urban roads. The software used will be AIMSUN (Siemens) or VISSIM (PTV) whose teaching licenses will be assigned by the responsible teacher in tutorial classes.
Ethical Principles
All members of a group are responsible for the group's work. In any assessment, every students shall honestly disclose any help received and sources used. In an oral assessment, every students shall be able to present and answer questions about the entire assignment and solution.
