01 / RESEARCH DIRECTIONS
Research shaped by real operating problems
For high-speed maglev transport systems, we study transport organization, operational dispatching and train optimization, with particular attention to coordination among transport plans, train control and traction power. We also investigate low-speed maglev freight models and planning assessment.
01
High-speed maglev networks and techno-economic analysis
Relationships between high-speed maglev and existing high-speed rail networks, including demand, service organization, system conditions, applicable scenarios and economic comparison.
02
Transport organization and operational dispatching
Coordination among departure times, section running times and demand, with emphasis on timetabling, line capacity and service adjustment.
03
Train speed profiles and energy-efficient operation
Speed profiles shaped by running time, energy and safety constraints, including auxiliary stopping areas, line conditions, traction characteristics and levitation energy.
04
Coordination of organization, control and traction power
Formal modeling, layered optimization and operating-strategy generation across transport planning, train control and traction power.
05
Low-speed maglev freight models and planning assessment
Low-speed permanent-magnet maglev freight models and transport organization for urban logistics, including capacity and cost analysis.
