Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Home Courses Traffic Flow Theory and Simulation Course materials Lectures 10. Car-following and stability by V.L. Knoop

10. Car-following and stability by V.L. Knoop

Course subject(s) 09. Car-following

This lecture will discuss the three-phase traffic flow theory of Kerner and the phenomena capacity drop. The Wiedeman principle including action point modeling will be discussed. A short explanation on cellular automata models will be provided. The process of calibrating a car-following model is extensively discussed. This includes techniques on measuring the traffic flow and the implication of parameters. To conclude this lecture an exercise will be given.

After this lecture you should be able to comment on Wiedeman’s principle,  draw the  associated diagrams and explain what action point modeling is. You should also be able to comment on the calibration of parameters of car-following behavior, capacity, capacity drop and the queue discharge rate. When possible you should be able to relate parameters of car-following models to macroscopic quantities.
