Intelligent Cruise Control Systems and Traffic Flow Stability

This paper illustrates how spacing policies used in vehicle following control laws change the macroscopic behavior of automated traffic and traffic flow stability. The effect of spacing policy used by Intelligent Cruise Control (ICC) systems on traffic flow stability is first studied. This is followed by an analysis of how the dynamics of an ICC system affects traffic flow stability. Using such an analysis the authors show that cruise control systems that use a constant time headway policy lead to unacceptable characteristics for the traffic flows.
