Fairness-Enhancing Vehicle Rebalancing in the Ride-hailing System

no code implementations29 Dec 2023 Xiaotong Guo, Hanyong Xu, Dingyi Zhuang, Yunhan Zheng, Jinhua Zhao

The results suggest that our proposed method enhances both accuracy and fairness in forecasting ride-hailing demand, ultimately resulting in more equitable vehicle rebalancing in subsequent operations.


Fairness-enhancing deep learning for ride-hailing demand prediction

no code implementations10 Mar 2023 Yunhan Zheng, Qingyi Wang, Dingyi Zhuang, Shenhao Wang, Jinhua Zhao

When coupled with the bias mitigation regularization method, the de-biasing SA-Net effectively bridges the mean percentage prediction error gap between the disadvantaged and privileged groups, and also protects the disadvantaged regions against systematic underestimation of TNC demand.


Simulating the Integration of Urban Air Mobility into Existing Transportation Systems: A Survey

no code implementations25 Jan 2023 Xuan Jiang, Yuhan Tang, Junzhe Cao, Vishwanath Bulusu, Hao, Yang, Xin Peng, Yunhan Zheng, Jinhua Zhao, Raja Sengupta

Urban air mobility (UAM) has the potential to revolutionize transportation in metropolitan areas, providing a new mode of transportation that could alleviate congestion and improve accessibility.
