This book was released on 1984-12 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ninth International Symposium on Transportation and Traffic Theory, held in the Netherlands in July 1984, follows the tradition of broad international information exchange that was developed at the eight previous symposia. Over the years the scope of the symposia has gradually widened to become both more international and more comprehensive than that of the earlier meetings. The Ninth Symposium continues this trend by including papers on a wide range of theoretical issues by leading members of the international research community.

Available in PDF, EPUB and Kindle. Book excerpt: This report examined several methods for estimating Origin-Destination (OD) matrices for freeways using loop detector data. Least squares based methods were compared in terms of both off-line and on-line estimation. Simulated data and observed data were used for evaluating the static and recursive estimators. For off-line estimation, four fully constrained least squares methods were compared. The results showed that the variations of a constrained least squares approach produced more efficient estimates. For on-line estimation, two recursive least squares algorithms were examined. The first method extends Kalman Filtering to satisfy the natural constraints of the OD split parameters. The second was developed from sequential quadratic programming. These algorithms showed different capabilities to capture an abrupt change in the split parameters. Practical recommendations of the choice of different algorithms are given.

This book was released on 2004 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin-destination (O-D) trip table is a key input required for traffic assignment and simulation models utilized to analyze a wide variety of transportation applications. The main goal of this research is to develop an economical and quick method for estimating O-D trip tables from traffic counts. Path flow estimator (PFE), originally developed by Bell and Shield (1995), has been further developed to improve the reliability and efficiency of O-D trip table estimates. The research reported herein includes only the development of the steady-state O-D estimator. In this study, the original PFE model was carefully examined in several aspects to gain more insight for further improvements. Currently, the PFE has been successfully applied to estimate 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. The most difficult task observed thus far is the estimation of spatial pattern of O-D demands even when traffic counts were collected on all network links. These issues and the development of time-dependent PFE will be investigated in the second phase under Task Order 5502
