Available in PDF, EPUB and Kindle. Book excerpt: Description: Travel time estimations created by processing of simulated freeway loop detector data using proposed method have been compared with travel times reported from VISSIM model. An improved methodology was proposed to estimate freeway corridor travel time under congested traffic. Field data were also collected using the floating car method and comparison of the estimated with the field measured travel times was made.

This book was released on 2001 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: GIS data and tools are revolutionizing transportation research and decision making, allowing transportation analysts and professionals to understand and solve complex transportation problems that were previously impossible. Here, Miller and Shaw present a comprehensive discussion of fundamental geographic science and the applications of these principles using GIS and other software tools. By providing thorough and accessible discussions of transportation analysis within a GIS environment, this volume fills a critical niche in GIS-T and GIS literature.
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.

Download or read book Urban Mobility Report 2004 written by David Schrank and published by DIANE Publishing. This book was released on 2008-10 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congestion continues to grow in America¿s urban areas. This report presents details on the 2004 trends, findings and what can be done to address the growing transportation problems. Trend data from 1982 to 2002 for 85 urban areas provides both a local view and a national perspective on the growth and extent of traffic congestion. The 2004 Report provides clear evidence that the time for improvements has arrived. Communicating the congestion levels and the need for improvements is a goal of this report. The decisions about which, and how much, improvement to fund will be made at the local level according to a variety of goals, but there are some broad conclusions that can be drawn from this database.

Download or read book Mainstreaming Climate Co Benefits in Indian Cities written by Mahendra Sethi and published by Springer. This book was released on 2018-02-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a novel framework to understand urban climate co-benefits in India, that is, tackling climate change and achieving sustainable development goals in cities. It utilizes methods and tools from several assessment frameworks to scientifically evaluate sector co-benefits for informed decision making. The co-benefits approach can lead to significant improvements in the way societies use environmental resources and distribute their outputs. The volume discusses four main themes: (1) Concepts and theories on cities and climate co-benefits; (2) Contextualizing co-benefit issues across spatial scales and sectors; (3) Sectoral analyses of co-benefits in energy, transport, buildings, waste, and biodiversity, and (4) Innovations and reforms needed to promote co-benefits in cities. The discussions are based on empirical research conducted in Indian cities and aligned with the international discourse on the 2030 UN Development Agenda and New Urban Agenda created at the UN-Habitat III in 2016. The analyses and recommendations in this volume are of considerable interest to policy experts, scholars and researchers of urban and regional studies, geography, public policy, international development/law, economics, development planning, environmental planning, climate change, energy studies, and so on.
