Aerodynamic Drag Coefficient Analysis of Heavy-Duty Vehicle Platoons: A Hybrid Approach Integrating Wind Tunnel Experiments and CFD Simulations

Energies
Heavy-duty vehicle (HDV) platooning, facilitated by vehicle-to-vehicle communication, plays a crucial role in transforming logistics and transportation. It reduces fuel consumption and emissions while enhancing road safety, supporting sustainable freight

Safe longitudinal platoons of vehicles without communication [PDF]

2009 IEEE International Conference on Robotics and Automation, 2009
This report deals with the platooning problem that can be defined as the automatic following of a manned driven vehicle by a convoy of automatic ones. Different approaches have been proposed so far. Some require the localisation of each vehicle and a communication infrastructure, others called near-to-near approach only needs vehicle on-board sensors ...

System Integration and Field Testing of Low‐Cost Autonomous Platooning Platforms: Collision Avoidance Scenario

Journal of Field Robotics, Volume 43, Issue 2, Page 847-878, March 2026.
ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.

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 ...

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.

Symmetry breaking in optimal timing of traffic signals on an idealized two-way street

, 2013
Simple physical models based on fluid mechanics have long been used to understand the flow of vehicular traffic on freeways; analytically tractable models of flow on an urban grid, however, have not been as extensively explored.

LSTM‐Based Centralized/Decentralized Controller Design for Vehicular Platooning

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper explores the development of a controller for vehicle platooning utilizing long short‐term memory (LSTM) networks. We, in particular, aim to address the complex control requirements necessary for adapting to the diverse movement patterns of human‐operated leading vehicle. The LSTM‐based controller is trained not only to achieve convergence to

CAVVPM: Challenge-Based Authentication and Verification of Vehicle Platooning at Motorway

Sensors, 2022
As a result of vehicle platooning, advantages including decreased traffic congestion and improved fuel economy are expected. Vehicles in a platoon move in a single line, closely spaced, and at a constant speed.

Learning to Love Rats: A Postwar Ecology in a Cambodian Minefield

American Anthropologist, Volume 127, Issue 4, Page 746-756, December 2025.
ABSTRACT This paper follows the implementation of landmine detection rats in Cambodia. Over the course of my ethnographic fieldwork with the team for the landmine detection rat technique training in Cambodia, I saw that the way the human landmine detectors (a.k.a.

Drayage Routing Problems: A Comprehensive Survey and a New Compact Model

Australian &New Zealand Journal of Statistics, Volume 67, Issue 4, Page 491-526, December 2025.
ABSTRACT Drayage involves short‐distance container trucking, a crucial part of intermodal transportation that fills the gap between long‐haul transportation modes and inland facilities. Because of its high costs, drayage has been increasingly drawing the attention of researchers and practitioners from different disciplines, who have been exploring ...
