Deep Reinforcement Learning Based Framework for Mobile Energy Disseminator Dispatching to Charge On-the-Road Electric Vehicles

no code implementations29 Aug 2023 JiaMing Wang, Jiqian Dong, Sikai Chen, Shreyas Sundaram, Samuel Labi

In the first component of the framework, we develop a realistic reinforcement learning environment termed "ChargingEnv" which incorporates a reliable charging simulation system that accounts for common practical issues in wireless charging deployment, specifically, the charging panel misalignment.

Scalable Traffic Signal Controls using Fog-Cloud Based Multiagent Reinforcement Learning

no code implementations11 Oct 2021 Paul, Ha, Sikai Chen, Runjia Du, Samuel Labi

However, it has been computationally difficult to scale these solution approaches to large networks partly due to the curse of dimensionality that is encountered as the number of intersections increases.

Urban traffic dynamic rerouting framework: A DRL-based model with fog-cloud architecture

no code implementations11 Oct 2021 Runjia Du, Sikai Chen, Jiqian Dong, Tiantian Chen, Xiaowen Fu, Samuel Labi

To address this question, this study proposes a two-stage model that combines GAQ (Graph Attention Network - Deep Q Learning) and EBkSP (Entropy Based k Shortest Path) using a fog-cloud architecture, to reroute vehicles in a dynamic urban environment and therefore to improve travel efficiency in terms of travel speed.

Estimating IRI based on pavement distress type, density, and severity: Insights from machine learning techniques

no code implementations11 Oct 2021 Yu Qiao, Sikai Chen, Majed Alinizzi, Miltos Alamaniotis, Samuel Labi

However, it is costly to measure IRI, and for this reason, certain road classes are excluded from IRI measurements at a network level.

A DRL-based Multiagent Cooperative Control Framework for CAV Networks: a Graphic Convolution Q Network

1 code implementation12 Oct 2020 Jiqian Dong, Sikai Chen, Paul Young Joun Ha, Yujie Li, Samuel Labi

Connected Autonomous Vehicle (CAV) Network can be defined as a collection of CAVs operating at different locations on a multilane corridor, which provides a platform to facilitate the dissemination of operational information as well as control instructions.

Leveraging the Capabilities of Connected and Autonomous Vehicles and Multi-Agent Reinforcement Learning to Mitigate Highway Bottleneck Congestion

no code implementations12 Oct 2020 Paul Young Joun Ha, Sikai Chen, Jiqian Dong, Runjia Du, Yujie Li, Samuel Labi

In addressing this objective, we duly recognize that one of the main challenges of RL-based CAV controllers is the variety and complexity of inputs that exist in the real world, such as the information provided to the CAV by other connected entities and sensed information.
