03 · Intelligent VehiclesScenario-adaptive perception
Computational tools for reliable, coordinated mobility systems.
Across rail control, metro networks, and cooperative perception, I focus on system modeling, optimization, learning, and decision-making under real operational constraints.

Intelligent Train Driving Assistance
Transferring globally optimized dynamic-programming policies into millisecond online decisions while preserving ATP safety protection and interpretable driver guidance.
Image preview: the original monitoring interface combines the line speed limit, ATP safety envelope, actual and predicted speed trajectories, and the active temporary-restriction region.

Metro Travel-Time Reliability
A network-scale analysis of Shanghai Metro AFC data using complementary reliability metrics, anomaly detection, regression, temporal analysis, and a management dashboard.

Scenario-Adaptive Multi-Vehicle Perception
Evaluating and optimizing multi-agent cooperative BEV perception across heterogeneous urban and highway scenarios with CARLA–SUMO–OpenCDA, uncertainty modeling, and NAS.
Cooperative Multi-UAV Delivery Scheduling & Route Planning
Ongoing work on coordinated scheduling and routing for multi-UAV delivery systems, with an emphasis on system-level optimization, multi-agent coordination, and last-mile logistics.
Optimization and decision-making for networked mobility systems.
I am especially interested in how sensing, planning, control, infrastructure, and operational decisions can be designed together rather than optimized in isolation.
Transportation Systems Optimization
Network performance, operations, reliability, and constrained system-level decision-making.
Networked & Autonomous Mobility
Interconnected agents, cooperative systems, and future mobility architectures.
Multi-Agent Coordination
Cooperative decision-making, routing and scheduling, and interaction under system constraints.
Simulation, Planning & Control
Scenario-based evaluation, co-simulation, algorithm design, and system-level control.
Academic training meets real-world systems.
