Scaling up the Optimal Safe Control of Connected and Automated Vehicles to a Traffic Network: A Hierarchical Framework of Modular Control Zones

no code implementations6 Aug 2023 Kaiyuan Xu, Christos G. Cassandras

We consider the problem of scaling up optimal and safe controllers for Connected and Automated Vehicles (CAVs) from a single Control Zone (CZ) around a traffic conflict area to an entire network.

Feasibility Guaranteed Traffic Merging Control Using Control Barrier Functions

no code implementations8 Mar 2022 Kaiyuan Xu, Wei Xiao, Christos G. Cassandras

We consider the merging control problem for Connected and Automated Vehicles (CAVs) aiming to jointly minimize travel time and energy consumption while providing speed-dependent safety guarantees and satisfying velocity and acceleration constraints.

Decentralized Time and Energy-Optimal Control of Connected and Automated Vehicles in a Roundabout

no code implementations13 Apr 2021 Kaiyuan Xu, Christos G. Cassandras, Wei Xiao

The paper considers the problem of controlling Connected and Automated Vehicles (CAVs) traveling through a three-entry roundabout so as to jointly minimize both the travel time and the energy consumption while providing speed-dependent safety guarantees, as well as satisfying velocity and acceleration constraints.

Adaptive Adversarial Logits Pairing

no code implementations25 May 2020 Shangxi Wu, Jitao Sang, Kaiyuan Xu, Guanhua Zheng, Changsheng Xu

Specifically, AALP consists of an adaptive feature optimization module with Guided Dropout to systematically pursue fewer high-contribution features, and an adaptive sample weighting module by setting sample-specific training weights to balance between logits pairing loss and classification loss.
