Download or read book Quantifying Incident induced Travel Delays on Freeways Using Traffic Sensor Data written by Yinhai Wang and published by . This book was released on 2008 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic congestion is a major operational problem for freeways in Washington State. Recent studies have estimated that more than 50 percent of freeway congestion is caused by traffic incidents. To help the Washington State Department of Transportation (WSDOT) identify effective countermeasures against such congestion-inducing incidents, a thorough understanding of travel delays caused by incidents is essential. By using traffic data extracted from archived loop detector measurements and incident log data recorded by the WSDOT Incident Response (IR) team, this research project developed a new algorithm for quantifying travel delays produced by different incident categories. The algorithm applies a modified deterministic queuing theory to estimate incident-induced delay by using 1-minute aggregated loop detector data. Incident-induced delay refers to the difference between the total delay and the recurrent travel delay at the time and location influenced by the incident. The uniqueness of the delay calculation in this study is the use of a dynamic traffic-volume-based background profile, which is considered a more accurate representation of prevailing traffic conditions. According to the test results, the proposed algorithm can provide good estimates for incident-induced delay and capture the evolution of freeway traffic flow during incident duration. Because actual traffic data measured by loop detectors were used in this study to compute vehicle arrival and departure rates for delay calculations, the estimated incident-induced delay should be very close to the reality. Additionally, the proposed algorithm was implemented in the Advanced Roadway Incident Analyzer (ARIA) system. ARIA is a database-driven computer system that automates all the computational processes. More accurate incident delay information will help WSDOT improve its understanding of congestion-inducing incidents and select more effective countermeasures against incident-related traffic congestion on freeways.

This book was released on 2006 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Freeway Management System (FMS) employs various tools to manage a freeway to increase throughput and reduce delay without additional lanes. The FMS acquires data from the roadway and process these data to identify and respond to problems. If some aspects of the data are unreliable, then the response decisions will likely be faulty. This study evaluates the performance of the first phase of the Columbus Metropolitan Freeway Management System (CMFMS) along roughly 14 miles (22.5 km) of I-70 and I-71. The system became operational at the end of 2001. The tools developed and the evaluation are intended to both provide a better understanding of the operation of the facility and to help guide future investments in the CMFMS and other FMSs. The initial objective of this study was to evaluate the performance of the CMFMS. In the course of the evaluation this effort developed calibration tools and performance measures that should also prove useful for ongoing operations. The study specifically develops a suite of performance monitoring tools both to assess the performance of instrumented freeways and the reliability of the surveillance system. It also provides a comprehensive overview of the given traffic monitoring system for practitioners, allowing them to optimize the system. In the course of this work we integrated information from many sources to meet multiple objectives for system management and monitoring. Although presented in the context of the Columbus system, the tools should be generalizable to most freeway surveillance systems.
