Cooperative Adaptive Cruise Control Strategy Optimization for Electric Vehicles Based on SA-PSO With Model Predictive Control

IEEE Access, 2020
The Cooperative Adaptive Cruise Control (CACC) is considered to be an effective method to improve traffic flow. However, the comfortability and economy need to be paid more attention to besides stability and safety.

Modelling the fundamental diagram of traffic flow mixed with connected vehicles based on the risk potential field

IET Intelligent Transport Systems, Volume 18, Issue 9, Page 1616-1631, September 2024.
In this study, the fundamental diagram (FD) of mixed traffic flows containing connected vehicles (CVs) and nonconnected vehicles (NCVs) was constructed within a unified framework. We derived the FD of mixed traffic flows based on the relationship between car‐following behavior and the macroscopic traffic flow under steady‐state conditions.

Impacts of connected vehicles in a complex, congested urban freeway setting using multi-resolution modeling methods

International Journal of Transportation Science and Technology, 2019
Determining the effect automated and connected vehicles could have on traffic flow would – ideally – require testing the vehicles themselves in a real-world environment. In the absence of large-scale, real-world testing, researchers used traffic modeling

Using Cooperative Adaptive Cruise Control (CACC) to Form High-Performance Vehicle Streams [PDF]

, 2014
This research identifies the operational concepts for managing cooperative adaptive cruise control (CACC) vehicle maneuvering and traffic flows. This includes approaches for grouping the CACC vehicles, ranging from ad-hoc to centrally coordinated strategies, and the incentives that could be used to facilitate the vehicle clustering, both operational ...

A simulation‐based impact assessment of autonomous vehicles in urban networks

IET Intelligent Transport Systems, Volume 18, Issue 9, Page 1677-1696, September 2024.
This research, conducts a simulation‐based impact assessment in a city‐wide network using optimized car following behaviour of autonomous vehicles. Abstract The behavioural differences between autonomous vehicles (AVs) and human‐driven vehicles (HDVs) can significantly impact traffic efficiency, safety, and emissions.

Nonlinear predictor‐feedback cooperative adaptive cruise control of vehicles with nonlinear dynamics and input delay

International Journal of Robust and Nonlinear Control, Volume 34, Issue 10, Page 6683-6698, 10 July 2024.
Summary We construct a nonlinear predictor‐feedback cooperative adaptive cruise control (CACC) design for homogeneous vehicular platoons subject to actuators delays, which achieves: (i) positivity of vehicles' speed and spacing states, (ii) ℒ∞$$ {\mathcal{L}}_{\infty } $$ string stability of the platoon, (iii) stability of each individual vehicular ...

Cooperative Adaptive Cruise Control (CACC) For Partially Automated Truck Platooning:Final Report [PDF]

, 2018
Cooperative Adaptive Cruise Control (CACC) provides an intermediate step toward a longer-term vision of trucks operating in closely-coupled automated platoons on both long-haul and short-haul freight corridors. There are important distinctions between CACC and automated truck platooning.

Assessing temporary traffic management measures on a motorway: Lane closures vs narrow lanes for connected and autonomous vehicles in roadworks

IET Intelligent Transport Systems, Volume 18, Issue 7, Page 1210-1226, July 2024.
A traffic microsimulation model was developed to evaluate two temporary traffic management measures under varying connected and autonomous vehicles market penetration rates. The model, validated with data from the M1 motorway in the UK, showed decreased delays and improved safety, particularly in narrow lanes, with increased connected and autonomous ...
