Research

Shared Mobility and Public Transit

• Joint optimization between planning and operations of DRT (Demand-Responsive Transit)

• Robotaxi (= autonomous taxi) parking/charging planning

• DRT for environmental sustainability and social equity

• Mixed planning between fixed-route and -schedule public transit and DRT

Mobility Electrification

• Public charging planning for private EVs (Electric Vehicle)

• Electrification of shared mobility and public transit (e.g., battery electric bus planning)

• Electric mobility hub network planning for multi-modal systems with electric and non-electric vehicles

• Understanding electric mobility ecosystem

Urban Air Mobility (UAM)

• Mobility hub planning for UAM and ground modes

• Evaluating environmental and social impacts of UAM

• Robust operational strategies

Autonomous Mobility

• Dedicated lane planning for AV/non-AV mixed traffic (AV: Autonomous Vehicle)

• Logistics systems with autonomous trucks

• Pavement and bridge management systems with AV sensors

Multi-Modal Mobility

• Data-driven trip chain analysis

• Multi-modal mobility planning based on the understanding of trip chain formation 

• Multi-modal system with autonomous/electric/shared modes

Infrastructure Management Systems

• Joint optimization of monitoring, inspection, maintenance, and reconstruction for large-scale  infrastructure systems such as highway/bridge/railway/airport networks

• Environmentally managed transportation asset

  • Life cycle analysis for reducing Greenhouse Gas emissions

Disaster Managements

• Pre-disaster and post-disaster infrastructure management 

  • Game-theoretical approaches in disaster management systems

  • Sea level rise and wildfire 

  • Graph-theoretical evaluation of mobility infrastructure vulnerability and resilience

  • Validation through agent-based simulations

Other Future Research Topics

• Inter-planetary traffic flow analysis and optimization (e.g., Earth-Mars Logistics)

• Environmental and social impacts of Purpose Built Vehicles (PBV) (e.g., mobile housing/hotel/cafe/...) 

  • Moving Points-of-Interest (POI) instead of distant and stationary POIs --> activity-based analysis is needed
