This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Travel time and delay are among the most important measures for gauging a transportation system's performance. To address the growing problem of congestion in the US, transportation planning legislation mandated the monitoring and analysis of system performance and produced a renewed interest in travel time and delay studies. Current techniques for collecting travel time and delay data range from manual data logging to completely automated, computer-aided record keeping. The techniques employed by the University of Delaware have evolved into a semi-automated system, but human and computer error still have the potential to create inaccuracies. In order to eliminate opportunities for human and computer error, a new GPSbased data collection technique was employed and compared directly with the currently accepted data collection methods. By simultaneously collecting data using three different techniques, the accuracy of the GPS positioning data and the resulting travel time and delay values could be objectively compared for automation and statistically compared for accuracy. It was found that the new technique provided the greatest automation requiring minimal attention of the data collectors and automatically processing the data sets. Using the Analysis of Means, Variances, Wilcoxon Signed Rank Test, and Pearson and Spearman Correlation Analyses, overall results showed that all data collection methods perform equally well for both travel time and delay time measurements.

This book was released on 2022-01-21 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the estimation of travel time in a very comprehensive and exhaustive way. Travel time information is and will continue to be one key indicator of the quality of service of a road network and a highly valued knowledge for drivers. Moreover, travel times are key inputs for comprehensive traffic management systems. All the above-mentioned aspects are covered in this book. The first chapters expound on the different types of travel time information that traffic management centers work with, their estimation, their utility and their dissemination. They also remark those aspects in which this information should be improved, especially considering future cooperative driving environments.Next, the book introduces and validates two new methodologies designed to improve current travel time information systems, which additionally have a high degree of applicability: since they use data from widely disseminated sources, they could be immediately implemented by many administrations without the need for large investments. Finally, travel times are addressed in the context of dynamic traffic management systems. The evolution of these systems in parallel with technological and communication advancements is thoroughly discussed. Special attention is paid to data analytics and models, including data-driven approaches, aimed at understanding and predicting travel patterns in urban scenarios. Additionally, the role of dynamic origin-to-destination matrices in these schemes is analyzed in detail.

Download or read book Traffic Planning and Engineering written by F. D. Hobbs and published by Elsevier. This book was released on 2016-01-21 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic Planning and Engineering, Second Edition takes into account underlying trends in traffic planning and engineering. In this edition, Chapter 3 has been remodeled, focusing on the techniques on conducting surveys and their subsequent analysis. Further emphasis has also been provided on environmental management and the central role of computers in all aspects of traffic planning and engineering. The topics discussed in this book include administration and planning in traffic engineering; traffic studies; traffic surveys and analysis; parking; traffic and environmental management; and road user, the vehicle and the road. The traffic stream and capacity; traffic control systems; street lighting, traffic signs, and carriageway markings; and accidents and road safety are also deliberated in this text. This publication is valuable to traffic engineering students, as well as individuals researching on techniques to achieve the safe and efficient movement of people and goods on roadways.
Download or read book The Effects of Travel Time Delay on Vehicle Miles Traveled and Travel Mode Choice Behavior written by Reza Sardari and published by . This book was released on 2021 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic congestion is a crucial factor for understanding travel behavior. The scientific evidence has shown that traffic congestion affects air quality, public health, and economic development, but empirical studies about the effects of travel time delays on travel behavior are limited. This research aims to address this gap by developing a time related mobility measure, or "delay score," and analyzing its impact on VMT and commuters' mode choices within a comprehensive framework that incorporates the built environment, demographics, and residential preference/self-selection factors. In this framework, VMT per household and travel mode choice were examined using SEM and GSEM techniques, respectively.This study used travel survey data from the 2015 Puget Sound Regional Council to analyze household daily VMT and commuter mode choice. Using GPS-based travel survey data combined with spatial analysis techniques, secondary data sources were considered in the analysis to examine factors such as VMT, non-motorized travel, and transit use. Built environment variables were measured at both the origins and destinations of trips. The study also incorporated socioeconomic and residential self-selection variables. Subsequently, factor analysis was used to represent residential self selection and the land use density dimension of the built environment.The findings indicate that higher travel time delay is associated with lower VMT per household, as doubling delay is associated with a 20 percent decrease in household VMT. The findings provide support for policies and regulations aiming to increase density and mixed-use development, reduce road capacity, and improve walkability and access to transit. Increasing the cost of driving relative to other modes is one strategy supported by smart growth policies to reduce VMT and encourage taking public transit or choosing non-motorized modes of travel. The findings suggest that access to free parking at workplaces encourages workers to drive alone, whereas providing free transit passes encourages them to take transit. Additionally, the results indicate that vehicle ownership--as a mid-term indicator--is more related to socioeconomic factors, whereas daily VMT--as a short-term indicator--is more related to built environment factors and residential self-selection. Future research should examine the effects of traffic congestion longitudinally and attempt to analyze disaggregated data at the national level to further our understanding of traffic congestion and its impacts on travel behavior.
