Road Traffic Modeling and Simulation

Tutorial

Linear car-following model with stability analysis

The microscopic modeling framework is based on individual vehicle motions in time and space [5]. Continuous time is denoted by

, while the spatial coordinate along the road by

. Then the position, speed and acceleration of a vehicle are

and

, respectively. We are interested in traffic flow modeling, therefore the focus is on vehicle interaction, rather than the details of vehicular motions. In the simplest car following description, the vehicle interaction is modeled through a ’stimulus-response’ relation, which expresses that drivers adjust their speed based on the speed difference with respect to the vehicle in front of them. In order to distinguish between vehicles, the subscript

is introduced and the acceleration of the

-th vehicle is written as1

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.
