Abstract:  In this talk, I shall discuss two problems in transportation research: (I) traffic demestimation in a star network (II) GPS trajectory data segmentation for identifying business points. We propose mathematical models for the captured problems by adopting the entropy-like maximization approach. Numerical algorithms based on Newton’s methods are designed to solve the optimization problems. Simulation experiments are then given to demonstrate the effectiveness efficiency of our methods.
