Stability and Optimal Design of Adaptive Linear Bus Holding on Open Chains and Loops
Li Zhen, Weihua Gu, Miny Shen +2
Bus holding can suppress bunching, but its stability and performance depend on the feedback structure and on how the bus sequence is bounded. This paper develops a common analytica…
Optimal designs of heterogeneous grid transit networks
Wenbo Fan, Haoyang Mao, Li Zhen +1
A general Continuum Approximation (CA) model is proposed for optimizing transit network designs (TND) in grid cities under spatially heterogeneous demand. While conventional studie…
Approximation Models for Shared Mobility Rebalancing Under Structured Spatial Imbalance
Wenbo Fan, Zhouyun Chen, Weihua Gu
Shared mobility systems (e.g., shared cars and ride-hailing services) generate persistent spatial imbalances as vehicles concentrate at popular destinations, leaving trip origins d…
Planning Skip-Stop Transit Service under Heterogeneous Demands
Yu Mei, Weihua Gu, Michael Cassidy +1
Transit vehicles operating under skip-stop service visit only a subset of the stops residing along a corridor. It is a strategy commonly used to increase vehicle speeds and reduce…
Revisit the scheduling problem in Hurdle, V.F., 1973: A novel mathematical solution approach and two extensions
Wenbo Fan
The scheduling problem in Hurdle (1973) was formulated in a general form that simultaneously concerned the vehicle dispatching, circulating, fleet sizing, and patron queueing. As a…
Traffic dynamics and optimal control in a city served by ride-sourcing vehicles
Wenbo Fan
This paper presents an interactive bathtub model for describing the traffic dynamics of ride-sourcing vehicles including non-shared taxis and ride-pooling cars. A city with a netwo…
