The Effect of IntelliDrive on the Efficiency of Highway Transportation Systems
Recently, the IntelliDrive initiative has been proposed by the US Department Of Transportation (USDOT) to enhance on-road safety and efficiency. In this paper, the authors provide a mathematical framework which predicts the effect of such technologies on the efficiency of multilane highway systems prior to their real-life deployment. Their study shall encompass mixed traffic conditions in which a variety of assisted, automated and unequipped vehicles coexist. They show that inter-vehicular communications improves the flow of vehicles by reducing the Perception-Reaction (P-R) times of drivers and, in some cases, allowing for more efficient lane-changing operations. As they shall see, unlike the latter, the former effect of IntelliDrive on driver P-R time is always there, regardless of the specific traffic conditions.
