Transit assignment and applications
Transit assignment is the process of assigning passengers traveling between various geographical locations to hyperpaths (collection of paths) in a transit network. It helps assess the impact of policies (e.g., raising fares or altering the frequency of a route) on passenger behavior. The current work on transit assignment focuses on building efficient algorithms for capacitated frequency-based and schedule-based transit assignment. Moreover, I'm also working on applications of transit assignment in designing online bus arrival and crowding information, designing network, fare pricing, and scheduling.
Public transit electrification
The deployment of electric buses for zero emissions and reduced noise offers many challenges to planners. I'm working on proposing novel methods for prioritizing routes for electrification, finding optimal charging stations, fleet planning, service timetable design, and vehicle scheduling considering the varying state of charge, battery degradation effect, driving range, random travel time, and queuing effects at charging stations.
Pricing design for integrated transit system
I am working on a mechanism that seamlessly integrates multiple transit options - such as local trains, taxis, metros, and buses - to provide passengers with a more convenient and efficient multimodal experience. The mechanism will determine the optimal passenger route, fare, and revenue allocation among the different operators, ensuring that each player benefits from participating in the integrated system.
