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 counts in 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 paper, we present the mathematical formulation of PFE, solution procedure, and software development of Visual PFE for estimating O-D trip tables. In addition, we highlight several practical extensions that will be added to Visual PFE to enhance its usability and capability.
