Learning "Look-Ahead" Nonlocal Traffic Dynamics in a Ring Road

no code implementations5 Dec 2023 Chenguang Zhao, Huan Yu

The macroscopic traffic flow model is widely used for traffic control and management.

Robust Safety for Mixed-Autonomy Traffic with Delays and Disturbances

no code implementations6 Oct 2023 Chenguang Zhao, Huan Yu

Considering both actuator and sensor delays, and disturbances, we propose robust safety-critical traffic control (RSTC) design to ensure ``robust safety'' of the mixed traffic.

Safety-Critical Traffic Control by Connected Automated Vehicles

no code implementations12 Jan 2023 Huan Yu, Chenguang Zhao, Tamas G. Molnar

Connected automated vehicles (CAVs) have shown great potential in improving traffic throughput and stability.

A Spatial-Temporal Attention Multi-Graph Convolution Network for Ride-Hailing Demand Prediction Based on Periodicity with Offset

no code implementations23 Mar 2022 Dong Xing, Chenguang Zhao, Gang Wang

To improve the efficiency of ride-hailing service, accurate prediction of transportation demand is a fundamental challenge.

PDLight: A Deep Reinforcement Learning Traffic Light Control Algorithm with Pressure and Dynamic Light Duration

1 code implementation29 Sep 2020 Chenguang Zhao, Xiaorong Hu, Gang Wang

Existing ineffective and inflexible traffic light control at urban intersections can often lead to congestion in traffic flows and cause numerous problems, such as long delay and waste of energy.

A Traffic Light Dynamic Control Algorithm with Deep Reinforcement Learning Based on GNN Prediction

1 code implementation29 Sep 2020 Xiaorong Hu, Chenguang Zhao, Gang Wang

Then, the results of traffic flow prediction are used in traffic light control, and the agent combines the predicted results with the observed current traffic conditions to dynamically control the phase and duration of the traffic lights at the intersection.
