Urban Road Networks

Course Description:

Urban Road Networks is part of 8th semester courses. It is compulsory for the students at the Transportation Planning and Engineering cycle. Lectures include design principles of urban road networks and more specifically of junctions (at grade or not), traffic signals, road signs and parking design and management. The course also includes parking counts by the students. Based on these counts students analyse the parking characteristics and the design of a parking area and optimize the signalization at an individual junction. The course foresees four hours of theory and exercises every week. During the exercises practical examples of applications are developed and in general the overall understanding of the course is assisted. It should be noted that there is no clear distinction between theory and exercises, since the theory relies on exercises and exercises deal with questions about the theory. Students consist of one class.

Prerequisite Knowledge

Knowledge of basic traffic Engineering principles which are taught at the Traffic Flow course (7th Semester) are prerequisite

Learning Objectives

Upon successful completion of the course, students will be able to:

  1. Learn the main types of signalisation and parking management
  2. Realise the ability to improve traffic flow through traffic control and parking management
  3. Understand the value of design principles for the signalization of a road network and the existence of regulations for the design of parking spaces
  4. Develop signalizing and parking principles
  5. Estimate through design principles basic parking and signalized parameters

Teaching Methods

Teaching methods Lectures Solutions of exercises Parking counts and submission of 3 individual projects
Teaching media Presentations through Power Point slides Microsoft Excel calculations
Computer and software use Students solve simple exercises during the lesson, with the support of the Professor
Assignments (projects, reports) Students create groups of 3 members and carry out parking counts at predefined zones of Athens. Based on these counts, the first two projects concern the analysis of parking characteristics and the design of a parking area. The third project concerns the optimization of signalization at an individual junction. Each student submits the three projects individually and is undertaking an oral exam on all of them.

Student Assessment

  • Final written exam: 70%
  • Assignments (projects, reports): 30%
  • Problems - Applications: Bonus +1 grade
