Strategic Hub-Based Platoon Coordination under Uncertain Travel Times

no code implementations1 Apr 2021 Alexander Johansson, Ehsan Nekouei, Karl Henrik Johansson, Jonas Mårtensson

We show that the platoon coordination game is a potential game when the travel times are either deterministic or stochastic, and the vehicles decide on their waiting times at the beginning of their journeys.

Multi-Fleet Platoon Matching: A Game-Theoretic Approach

no code implementations17 Feb 2022 Alexander Johansson, Ehsan Nekouei, Karl Henrik Johansson, Jonas Mårtensson

At a Nash equilibrium, vehicles with the same departure time are matched to form a platoon.

Real-Time Cross-Fleet Pareto-Improving Truck Platoon Coordination

no code implementations17 Feb 2022 Alexander Johansson, Jonas Mårtensson, Xiaotong Sun, Yafeng Yin

The profit of each fleet incorporates platooning rewards and costs for waiting at hubs.

Game Theoretic Models for Profit-Sharing in Multi-fleet Platoons

no code implementations17 Feb 2022 Alexander Johansson, Jonas Mårtensson

Profit-sharing is needed within platoons in order for competing transportation companies to collaborate in forming platoons.

Truck Platoon Formation at Hubs: An Optimal Release Time Rule

no code implementations18 Feb 2022 Alexander Johansson, Valerio Turri, Ehsan Nekouei, Karl H. Johansson, Jonas Mårtensson

The vehicles wait at the hub, and a platoon coordinator, at each time-step, decides whether to release the vehicles from the hub in the form of a platoon or wait for more vehicles to arrive.

Event-Triggered Distributed Model Predictive Control for Platoon Coordination at Hubs in a Transport System

no code implementations18 Feb 2022 Ting Bai, Alexander Johansson, Karl Henrik Johansson, Jonas Mårtensson

This paper considers the problem of hub-based platoon coordination for a large-scale transport system, where trucks have individual utility functions to optimize.

A Pricing Rule for Third-Party Platoon Coordination Service Provider

no code implementations21 Feb 2022 Ting Bai, Alexander Johansson, ShaoYuan Li, Jonas Mårtensson

To evaluate the effect of the pricing on the platooning system, we perform a simulation over the Swedish road network.

Approximate Dynamic Programming for Platoon Coordination under Hours-of-Service Regulations

no code implementations19 Aug 2022 Ting Bai, Alexander Johansson, Karl Henrik Johansson, Jonas Mårtensson

In our problem, trucks have fixed routes in a transportation network and can wait at hubs along their routes to form platoons with others while fulfilling the driving and rest time constraints.

Large-Scale Multi-Fleet Platoon Coordination: A Dynamic Programming Approach

no code implementations21 Jul 2023 Ting Bai, Alexander Johansson, Karl Henrik Johansson, Jonas Mårtensson

This paper presents a distributed framework for addressing multi-fleet platoon coordination in large transportation networks, where each truck has a fixed route and aims to maximize its own fleet's platooning profit by scheduling its waiting times at hubs.

Swarm Bug Algorithms for Path Generation in Unknown Environments

no code implementations15 Aug 2023 Alexander Johansson, Johan Markdahl

For SwarmBug2, we show that the algorithm underperforms in terms of worst-case travel time compared to SwarmBug1.

Hub-Based Platoon Formation: Optimal Release Policies and Approximate Solutions

no code implementations11 Nov 2023 Alexander Johansson, Ehsan Nekouei, Xiaotong Sun, Karl Henrik Johansson, Jonas Mårtensson

We first show that the optimal release policy in the decentralized case, where the hubs do not exchange information, is to release all trucks at the hub when the number of trucks exceeds a threshold computed by dynamic programming.
