Topic:

Visual PFE: A framework for estimating origin-destination trip tables from observed traffic data

Lecturer:Professor Anthony Chen,Utah State University

Time:2010.6.16(Wednesday), 11:00-12:00 a.m.

Location:New Main Building A1136

Organizer:The Department of Business Administration

Abstract:

Visual PFE is an integrated software suite that combines the Path Flow Estimator (PFE) with other software components to facilitate the estimation, visualization, and refinement of origin-destination (O-D) trip tables with user-friendly Graphical User Interfaces (GUI). The core of the Visual PFE is the PFE formulated as a convex program with side constraints for estimating path flows from traffic countsin a transportation network.

The estimated path flows can further be aggregated to obtain the O-D flows, which are usually required in many transportation applications. In this seminar, Dr. Chen will present a framework for estimating O-D trip tables from observed traffic data, which consists of the PFE formulation, solution procedure, and software development of Visual PFE. In addition, several recent extensions including three Lp-norm PFE models for handling traffic count inconsistencies, traffic counting location models for determining the number and locations of traffic counts for improving O-D trip table estimation, and quality assessment measures for evaluating the quality of estimated O-D trip table will be discussed in the seminar.
