Mobility Modeling

T Technical Teaching


(Course for Post Master and International Master students only).
  • The module teaches the state-of-the art of the modeling techniques for vehicular mobility. The objectives are first to describe the challenges of close-to-reality modeling of vehicular mobility, illustrate the impact of mobility on communication and networking, as well as the benefit of close-to-reality of vehicular mobility modeling to design efficient ITS applications.
  • This module covers the various modeling approaches, from vehicular flow modeling (at micro-, meso- and macroscopic level), to large-scale vehicular traffic modeling (Origin-Destination matrix, Trip and Path planning). This module concludes with a description and a survey of simulators related to the previously described models, and available to the ITS community for a multi-scale realistic vehicular mobility modeling.

Details of each section:

  • Vehicular Flow Modeling - Vehicular flow models describe the  movement of individual vehicles, typically as a function of their internal state, as well as of that of neighboring vehicles. These models represent microscopic-level car-to-car interactions and have been studied since the 50's. In this section, we present the history and state-of-art in vehicular flow modeling.
    • Objectives to the students: understanding the basics of vehicular flow modeling, and gaining a comprehensive and systematical view on the vast literature on the topic.
  • Vehicular Traffic Modeling  - When targeting a comprehensive and realistic representation of vehicular mobility, microscopic-level car-to-car interactions are only one part of the solution. Indeed, it is well known that vehicles follow macroscopic-level patterns determined by the nature of roads and by the habits of drivers. Thus, in this section we describe the various approaches to model such large-scale traffic behaviors, from random mobility to activity-based trip generation and agent-based modeling.
    • Objectives to the students: getting introduced to an underrated aspect of mobility, and understanding how it is typically dealt with in vehicular networking research.
  • Vehicular Traffic Simulators - Microscopic- and macroscopic-level models have been implemented, over the last 20 years, in vehicular traffic simulators. Initially expensive proprietary tools developed for transportation research, these simulators have recently been adapted to the needs of networking research, with the development of open source tools capable of interacting with network simulators. In this section, we present a taxonomy of traffic simulators for vehicular networking research, with a focus on the interactions between mobility and network simulators.
    • Objectives to the students: gaining a complete view on the available vehicular traffic simulators, and understanding their strengths and weaknesses.
