Infrastructure Management
About
Transportation systems are undergoing a fundamental transition to electrification. The shift to electrification via electric vehicles (EVs), charging infrastructure, and renewable energy can bring considerable benefits to society, such as climate change adaptation, air pollution reduction, and human well-being improvement. However, the present transportation-electrification-related infrastructure, particularly public charging infrastructure, is insufficient to support this transition, let alone an equitable charging supply for various communities.
The research comprehensively assesses the current gap between charging demand and supply in and across communities to prioritize those underserved communities and predict and compare each community’s demand profile for public chargers under multiple scenarios combining transportation network situations, zero-emission goals, and real-life charging preferences.
The research addresses EV related issues through three aspects: Charging Demand Prediction, EV Charging Infrastructure Planning, Resilience and Reliability.
Charging Demand Prediction
The research proposes a comprehensive modeling framework of gap assessment and demand profile projection concerning EVs (both passenger vehicles and trucks [light-, medium- and heavy-duty]) and public charging infrastructure in electrified transportation systems.

EV Charging Infrastructure Planning
The research predicts the electricity demands from the daily travel trajectories simulated in the digital twin model and the charging data from the mobility data companies (e.g., Wejo). The estimated spatial-temporal distribution of charging needs will contribute to the decision-making of agencies in the efficient and equitable planning of charging facilities.

Coming soon.
Resilience and Reliability
As EVs become more prevalent, the resilience and reliability of charging systems will be critical to the performance of future transportation systems. In this context, my research will also concentrate on the resilient charging infrastructure planning and management in response to the surging charge demand of large events (e.g., concerts), seasonal charging demand variations, and large-scale blackouts in the city.
