En-route Charging Coordination for Electric Trucks
Joas Kahlert, Ruiting Wang, Jonas Mårtensson
The electrification of long-haul freight transport introduces several new challenges, such as the limited capacity and congestion at en-route charging infrastructure. To reduce wai…
Congestion Forecasting for Electric Vehicle Charging Scheduling with Fluid Queues
Joas Kahlert, Ruiting Wang, Jonas Mårtensson
To support the adoption of electric transport systems, public charging opportunities are becoming increasingly important. In this dynamic environment, a central challenge for route…
Second Order Physics-Informed Learning of Road Density using Probe Vehicles
S. Betancur Giraldo, J. Mårtensson, M. Barreau
We propose a Physics Informed Learning framework for reconstructing traffic density from sparse trajectory data. The approach combines a second-order Aw-Rascle and Zhang model with…
Shared Situational Awareness Using Hybrid Zonotopes with Confidence Metric
Vandana Narri, Jonah J. Glunt, Joshua A. Robbins +3
Situational awareness for connected and automated vehicles describes the ability to perceive and predict the behavior of other road-users in the near surroundings. However, pedestr…
pyspect: An Extensible Toolbox for Automatic Construction of Temporal Logic Trees via Reachability Analysis
Kaj Munhoz Arfvidsson, Loizos Hadjiloizou, Frank J. Jiang +2
In this paper, we present pyspect, a Python toolbox that simplifies the use of reachability analysis for temporal logic problems. Currently, satisfying complex requirements in cybe…
Beyond Line-of-Sight: Cooperative Localization Using Vision and V2X Communication
Annika Wong, Zhiqi Tang, Frank J. Jiang +2
Accurate and robust localization is critical for the safe operation of Connected and Automated Vehicles (CAVs), especially in complex urban environments where Global Navigation Sat…
Leveraging Sidewalk Robots for Walkability-Related Analyses
Xing Tong, Michele D. Simoni, Kaj Munhoz Arfvidsson +1
Walkability is a key component of sustainable urban development. In walkability studies, collecting detailed pedestrian infrastructure data remains challenging due to the high cost…
Towards Safe Autonomous Intersection Management: Temporal Logic-based Safety Filters for Vehicle Coordination
Kaj Munhoz Arfvidsson, Frank J. Jiang, Karl H. Johansson +1
In this paper, we introduce a temporal logic-based safety filter for Autonomous Intersection Management (AIM), an emerging infrastructure technology for connected vehicles to coord…
Pedestrian Motion Prediction Using Transformer-based Behavior Clustering and Data-Driven Reachability Analysis
Kleio Fragkedaki, Frank J. Jiang, Karl H. Johansson +1
In this work, we present a transformer-based framework for predicting future pedestrian states based on clustered historical trajectory data. In previous studies, researchers propo…
Distributed Charging Coordination for Electric Trucks under Limited Facilities and Travel Uncertainties
Ting Bai, Yuchao Li, Andreas A. Malikopoulos +2
In this work, we address the problem of charging coordination between electric trucks and charging stations. The problem arises from the tension between the trucks' nontrivial char…
Ensuring Safety at Intelligent Intersections: Temporal Logic Meets Reachability Analysis
Kaj Munhoz Arfvidsson, Frank J. Jiang, Karl H. Johansson +1
In this work, we propose an approach for ensuring the safety of vehicles passing through an intelligent intersection. There are many proposals for the design of intelligent interse…
Small-Scale Testbed for Evaluating C-V2X Applications on 5G Cellular Networks
Kaj Munhoz Arfvidsson, Kleio Fragkedaki, Frank J. Jiang +4
In this work, we present a small-scale testbed for evaluating the real-life performance of cellular V2X (C-V2X) applications on 5G cellular networks. Despite the growing interest a…
Hub-Based Platoon Formation: Optimal Release Policies and Approximate Solutions
Alexander Johansson, Ehsan Nekouei, Xiaotong Sun +2
This paper studies the optimal hub-based platoon formation at hubs along a highway under decentralized, distributed, and centralized policies. Hubs are locations along highways whe…
Distributed Charging Coordination of Electric Trucks with Limited Charging Resources
Ting Bai, Yuchao Li, Karl Henrik Johansson +1
Electric trucks usually need to charge their batteries during long-range delivery missions, and the charging times are often nontrivial. As charging resources are limited, waiting…
