Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Traffic Oscillations Mitigation in Vehicle Platoon Using a Car-Following Control Model for Connected and Autonomous Vehicle

Journal of Advanced Transportation, 2019
Traffic oscillations often occur in road traffic, they make traffic flow unstable, unsafe and inefficient. Emerging connected and autonomous vehicle (CAV) technologies are potential solutions to mitigating the traffic oscillations for the advantages that

Distributed Nonlinear Model Predictive Control for Connected Autonomous Electric Vehicles Platoon with Distance-Dependent Air Drag Formulation

Energies, 2021
This paper addresses the leader tracking problem for a platoon of heterogeneous autonomous connected fully electric vehicles where the selection of the inter-vehicle distance between adjacent vehicles plays a crucial role in energy consumption reduction.

Microscopic features of moving traffic jams

, 2005
Empirical and numerical microscopic features of moving traffic jams are presented. Based on a single vehicle data analysis, it is found that within wide moving jams, i.e., between the upstream and downstream jam fronts there is a complex microscopic ...

A Relational Perspective on Land in Armed Conflict: Analysing the Village Guard Mobilisation in Turkey

Studies in Ethnicity and Nationalism, EarlyView.
ABSTRACT This article examines the Turkish state's Village Guard system, revived in the 1980s as part of its counterinsurgency strategy against the Kurdistan Workers Party (PKK). While often framed as a defensive militia, the Village Guards became central to the state's exceptional governance in Kurdistan, both facilitating military control and ...

Cooperative control of mixed vehicle platoon based on pinning consensus of heterogeneous multi‐agent system

IET Intelligent Transport Systems
This paper proposes a longitudinal controller for the mixed vehicle platoon in the presence of driver response time‐delay and communication time‐delay based on the pinning consensus of heterogeneous multi‐agent system.

Efficient Message Relaying Scheme for Heterogeneous Platoons

The Journal of Korean Institute of Communications and Information Sciences, 2016
In heterogeneous platoons, consisting of various size of vehicles, the signal from/to a small-size vehicle may be blocked by adjacent large-size ones. In this case, some vehicles in between the source and the destination should relay the messages. We design an efficient message relaying scheme for these platoons and evaluate its performance, taking the

String stability of heterogeneous platoons with non-connected automated vehicles

2017 IEEE 20th International Conference on Intelligent Transportation Systems (ITSC), 2017
It is expected that automated vehicles will gradually penetrate on public roads, resulting in mixed traffic in the next decades. This can impact traffic flow operations, especially the roadway capacity and flow stability. It is of paramount importance to understand and predict the implications of automated driving systems on traffic flow at the early ...

Signal Timing and CAV Trajectory Joint Control Under Mixed Vehicular Environments With Hierarchical Proximal Policy Optimisation

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper introduces SVCC‐HPPO, a novel Signal‐Vehicle Cooperative Control framework using an improved Hierarchical Proximal Policy Optimisation (H‐PPO) algorithm to jointly optimise traffic signal timing and Connected/Autonomous Vehicle (CAV) trajectories in mixed traffic environments.

Federated Robust Embedded Systems: Concepts and Challenges [PDF]

, 2012
The development within the area of embedded systems (ESs) is moving rapidly, not least due to falling costs of computation and communication equipment. It is believed that increased communication opportunities will lead to the future ESs no longer being ...
