BTE-Sim: Fast simulation environment for public transportation

Published in 2022 IEEE International Conference on Big Data, 2022

Public transit is vital for cities but often stagnates due to static design. BTE-Sim, a fast, multi-layered transit simulation, analyzes population demand, traffic, and road networks to optimize routes, evaluate changes, and improve efficiency with low computation time.

Grid-Aware Charging and Operational Optimization for Mixed-Fleet Public Transit

Published in 27th IEEE International Conference on Intelligent Transportation Systems, 2024

This study presents a robust hierarchical MILP model that optimizes charging and trip assignments for mixed bus fleets (electric and internal combustion engine buses), cutting costs and enhancing sustainability using real-world data from Chattanooga, Tennessee.

Online Decision-Making Under Uncertainty for Vehicle-to-Building Systems

Published in 16th ACM/IEEE International Conference on Cyber-Physical Systems, 2025

Vehicle-to-Building (V2B) systems optimize EV charging and discharging to cut costs, but complexity arises from pricing, planning, and user constraints; we model it as an MDP and use online search with heuristics, achieving state-of-the-art results in real-world tests using data from an EV manufacturer.
