Delivery Time Inference Based on Couriers' Trajectories

Leveraging large-scale courier trajectory data and spatiotemporal analytics, the DTInf framework infers parcel delivery times by detecting stay points, correcting delivery locations, and matching delivery events using a trained MLP model, achieving a mean absolute error of 401 seconds and outperforming baselines by over 30%.
