Journal ArticleDOI
Dissipation of stop-and-go waves via control of autonomous vehicles: Field experiments
Raphael Stern,Shumo Cui,Maria Laura Delle Monache,Rahul Bhadani,Matt Bunting,Miles Churchill,Nathaniel Hamilton,R’mani Haulcy,Hannah Pohlmann,Fangyu Wu,Benedetto Piccoli,Benjamin Seibold,Jonathan Sprinkle,Daniel B. Work,Daniel B. Work +14 more
TL;DR: It is demonstrated experimentally that intelligent control of an autonomous vehicle is able to dampen stop-and-go waves that can arise even in the absence of geometric or lane changing triggers, suggesting a paradigm shift in traffic management.
Proceedings ArticleDOI
Stabilizing traffic flow via a single autonomous vehicle: Possibilities and limitations
TL;DR: This work studies under which circumstances the presence of a single autonomous vehicle can locally stabilize the flow, without changing the way the humans drive, to enable traffic flow control via very few AVs serving as mobile actuators.
Journal ArticleDOI
Are Commercially Implemented Adaptive Cruise Control Systems String Stable
George Gunter,Derek Gloudemans,Raphael Stern,Sean T. McQuade,Rahul Bhadani,Matt Bunting,Maria Laura Delle Monache,Roman Lysecky,Benjamin Seibold,Jonathan Sprinkle,Benedetto Piccoli,Daniel B. Work +11 more
TL;DR: In this paper, the string stability of seven 2018 model year adaptive cruise control (ACC) equipped vehicles that are widely available in the US market is assessed using data collected from more than 1,200 miles of driving in car following experiments with ACC engaged by the follower vehicle.

Are commercially implemented adaptive cruise control systems string stable
George Gunter,Derek Gloudemans,Raphael Stern,Sean T. McQuade,Rahul Bhadani,Matt Bunting,Maria Laura Delle Monache,Roman Lysecky,Benjamin Seibold,Jonathan Sprinkle,Benedetto Piccoli,Daniel B. Work +11 more
TL;DR: The string stability of the data-fitted model associated with each vehicle is assessed, and the main finding is that all seven vehicle models have string unstable ACC systems.
Journal ArticleDOI
Quantifying air quality benefits resulting from few autonomous vehicles stabilizing traffic
Raphael Stern,Raphael Stern,Yuche Chen,Miles Churchill,Fangyu Wu,Maria Laura Delle Monache,Benedetto Piccoli,Benjamin Seibold,Jonathan Sprinkle,Daniel B. Work +9 more
TL;DR: In this paper, the authors investigated the potential reduction of vehicular emissions caused by the whole traffic stream, when a small number of autonomous vehicles (e.g., 5% of the vehicle fleet) are designed to stabilize the traffic flow and dampen stop-and-go waves.
