In this paper, the authors address the problem of uncoordinated highway traffic. They first identify the main causes of the capacity drop, namely high traffic demand and inadequate driver reaction. In the past, traffic and user behavior have been accurately described by Cellular Automata (CA) models. In this paper, they extend the CA model to deal with highway traffic fluctuations and jams. Specifically, the model incorporates the communication layer between vehicles. The model thus enables one to study the impact of inter-vehicular communications and in particular the delivery of critical and timely upstream traffic information on driver reaction.
