Stabilization of traffic through cooperative autonomous vehicles

Participants : Guy Fayolle, Carlos Flores, Jean-Marc Lasgouttes.

We investigate inĀ [26] the transfer function emanating from the linearization of a car-following model, when taking into account a driver reaction time. This leads to stability conditions, which are explicitly given. We also show how this reaction time can introduce a weak string instability.

This paper is intended as a foundation of a larger work on traffic stabilization by means of a fleet of cooperative automated vehicles. Contrary to some earlier works, our approach is based on a car-following model with reaction-time delay, rather than on a first order fluid model. The continuation of these studies will concern schockwave analysis and adequate traffic-stabilizing control strategies.
