On the one hand, the workbook serves the English Master Program of Autonomous Vehicle Control Engineer at the Faculty of Transportation Engineering and Vehicle Engineering of Budapest University of Technology and Economics. The exercises provide basic tutorial training supporting the course of Road Traffic Modeling and Control. On the other hand, the traffic modeling and simulation basics given in this book also lay the groundwork for practical and theoretical contributions in the field of intelligent traffic systems and traffic control.
