Disturbance propagation and string stability of a large vehicle platoon that consists of a part of the traffic flow is closely related
to traffic shockwaves and oscillation. In this respect, the concepts of the estimation and prediction of shockwave propagation
speeds and congestion should be considered in order to establish a control strategy for safe conditions without collisions even when
the congestion is amplified in an unstable string of the large platoon. This means that an advanced approach for a car-following
control strategy, which includes a time delay and non-linearity terms, is necessary for the enhancement of Vehicle Platoon Control
(VPC) and the system robustness. In this research, we have demonstrated the effect of the disturbance propagation phenomenon
on traffic flow stability. The traffic flow shockwave and oscillation are interpreted in terms of both macroscopic and microscopic
approaches. We also discuss how the phenomenon affects VPC systems based on the optimal velocity model (OVM), which is an
advanced car-following model. In addition, we improve the OVM, which is called the advanced OVM, by including a term for the
delay time and by setting up a boundary condition of acceleration in order to enhance the VPC system and to ensure its robustness

Jinsoo Kim received the BS degree in Traffic Engineering from Hanyang University, Seoul, Korea, in 2010 and the MS degree in Traffic Engineering from Hanyang University,
Seoul, Korea, in 2012. He is currently pursuing his PhD degree in Mechanical Convergence Engineering at Graduate School of Hanyang University. From 2013 onwards, he
is Research Assistant with the Institute of Mechanical Technology, Hanyang University, Seoul, Korea. His research interest includes the development of intelligent vehicle
and traffic systems through vehicle and traffic flow dynamics with optimal control. His awards and honors include the Global PhD Fellowship (National Research Foundation
of Korea grant funded by the Korea government (MEST)), the Best Paper Award in Proceedings of the ITS Conference and the Prize of Korean Society of Transportation.
