Development of a Path Flow Estimator for Deriving Steady-State and Time-Dependent Origin-Destination Trip Tables

Origin-destination (O-D) trip table serve as a key input for traffic assignment and simulation models. The focus of this research was to develop an economical and quick method for estimating O-D trip tables from traffic counts. In this study, the original Path Flow Estimator (PFE) model was examined in order to gain insight into further improvements. The study discusses the successful application of the PFE for estimating the steady-state O-D trip tables for the Irvine Testbed network in Orange County, California as well as some other real networks. The primary results demonstrate that PFE has the capability to correctly estimate the total and individual O-D demands when proper information is provided. They also indicate that the number and locations of traffic counts significantly influence the quality of O-D estimates as each observation contributes different amount and quality of information.
