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 ...

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

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 ...

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 ...

Trajectory Planning for Multiple Autonomous Vehicles at Short‐Distance Tandem Signalized Intersections Based on Rule‐Free Framework

Advanced Intelligent Systems, Volume 6, Issue 6, June 2024.
Herein, a rule‐free trajectory planning framework for multiple Autonomous Vehicles (AVs) is designed to optimizing flow distribution between upstream and downstream intersections of mixed flow at near‐saturated short‐distance tandem signalized intersections. The framework can be used to explore optimal efficiency for mixed flow and better heterogeneous
