Empirical Study on the Properties of Adaptive Cruise Control Systems and Their Impact on Traffic Flow and String Stability
An experimental campaign with five vehicles equipped with ACC was conducted at the proving ground of AstaZero in Sweden to improve understanding on the properties of ACC systems and their functionality under real driving conditions, with main parameters under investigation are the response time of controllers, the available time headway settings, and the stability of the car-platoon.
Car-following Model of Connected Cruise Control Vehicles to Mitigate Traffic Oscillations
A car-following model for Connected Cruise Control systems is extended by considering electronic throttle angles of multiple cars ahead by finding that the proposed model is prominently better than the previous model from the perspective of mitigating traffic oscillations.
Stability Analysis of a Macroscopic Traffic Flow Model for Adaptive Cruise Control Systems
A stability threshold is derived of a novel macroscopic model, developed to simulate the flow of ACC-equipped vehicles, and the impact of such vehicles on the stabilization of the traffic flow, with respect to small perturbations is studied.
Impact of different spacing policies for adaptive cruise control on traffic and energy consumption of electric vehicles
It is found that ACC with quadratic spacing policy has significantly positive effects on string stability and energy consumption.
Estimating empirically the response time of commercially available ACC controllers under urban and freeway conditions
The present work presents further results on two more commercially available controllers and tests their response in both urban and highway driving conditions under normal driving behavior without critical situations regarding the safety of the vehicle’s passengers.
Evaluating the Impacts of Adaptive Cruise Control Systems on Congested Urban Freeways and Emphasizing the Need for New Traffic Control Strategies
The introduction of CAVS will transform the future of transportation, and there is a need to quantify the effect of such technologies on congested urban transportation systems and potentially steer their effect in a positive direction by implementing appropriate traffic control strategies.
Car-following Characteristics of Adaptive Cruise Control from Empirical Data
This simulation shows how changes in perception abilities, precision control, and reaction times in computer-driven vehicles will change how these vehicles behave in the real-world.
Meta-Analysis of Adaptive Cruise Control Applications: Operational and Environmental Benefits
With the increasing adoption of adaptive cruise control (ACC) and development of cooperative adaptive cruise control (CACC), their effect on traffic, energy, and emissions is an ever more urgent
Predictor-Based Adaptive Cruise Control Design
By employing an input–output approach, it is shown that the predictor-based adaptive cruise control law with integral action guarantees all of the four typical performance specifications of adaptive Cruise Control designs, namely, 1) stability, 2) zero steady-state spacing error, 3) string stability, and 4) non-negative impulse response, despite the large input delay.


Impacts of Cooperative Adaptive Cruise Control on Freeway Traffic Flow
This study used microscopic simulation to estimate the effect on highway capacity of varying market penetrations of vehicles with adaptive cruise control (ACC) and cooperative adaptive cruise control

The flow of traffic composed of vehicles that are equipped with adaptive cruise control (ACC) is studied using simulations and a state closely related to the synchronized flow phase found in manually driven vehicular traffic has been observed.
Effect of adaptive cruise control systems on traffic flow.
The flow of traffic composed of vehicles that are equipped with adaptive cruise control (ACC) is studied using simulations. The ACC vehicles are modeled by a linear dynamical equation that has string
Enhanced intelligent driver model to access the impact of driving strategies on traffic capacity
A new car-following model is proposed that also serves as the basis of an ACC implementation in real cars and eliminates the sometimes unrealistic behaviour of the IDM in cut-in situations with ensuing small gaps that regularly are caused by lane changes of other vehicles in dense or congested traffic.
This report describes a research program focused on the influences of adaptive cruise control (ACC)-equipped vehicles on traffic behavior. The program is directed at increasing the understanding of
