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…
Design of Transit Networks: Global Optimization of Continuous Approximation Models via Geometric Programming
Haoyang Mao, Weihua Gu, Wenbo Fan +2
Continuous approximation (CA) models have been widely adopted in transit network design studies due to their strong analytical tractability and high computational efficiency. Howev…
Fly-by transit: A novel door-to-door shared mobility with minimal stops
Wenbo Fan, Weihua Gu
This paper introduces fly-by transit (FBT), a novel mobility system that employs modular mini-electric vehicles (mini-EVs) to provide door-to-door shared mobility with minimal stop…
Optimal design of ride-pooling as on-demand feeder services
Wenbo Fan, Weihua Gu, Meng Xu
The technology-enabled ride-pooling (RP) is designed as an on-demand feeder service to connect remote areas to transit terminals (or activity centers). We propose the so-called ``h…
