Book excerpt: This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, sets out requirements for travel time reliability within a performance-based planning process. The research includes an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. The report includes two succinct tables that describe requirements for person and freight trips for reliable transport, as well as a forecast of the year 2030 under alternative assumptions that may influence travel time reliability.

Available in PDF, EPUB and Kindle. Book excerpt: The research included an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. This method is predicated on determining the certainty equivalent of the variability of speed. This innovative approach, briefly summarized in the body of the report and described in an appendix, deserves further exploration despite the lack of consensus from experts about its validity. A prominent part of the report presents a forecast of the year 2030 under alternative assumptions that may influence travel time reliability. The researchers set out three alternative outcomes--optimistic, mediocre, and pessimistic--regarding climate change, economics, and demographics. In addition, they examined a range of technological developments that might affect reliability. To paint a picture of the future, they prepared a concept of operations for the year 2030.

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.

Book excerpt: A multi-disciplinary approach to transportation planningfundamentals The Transportation Planning Handbook is a comprehensive,practice-oriented reference that presents the fundamental conceptsof transportation planning alongside proven techniques. This newfourth edition is more strongly focused on serving the needs of allusers, the role of safety in the planning process, andtransportation planning in the context of societal concerns,including the development of more sustainable transportationsolutions. The content structure has been redesigned with a newformat that promotes a more functionally driven multimodal approachto planning, design, and implementation, including guidance towardthe latest tools and technology. The material has been updated toreflect the latest changes to major transportation resources suchas the HCM, MUTCD, HSM, and more, including the most current ADAaccessibility regulations. Transportation planning has historically followed the rationalplanning model of defining objectives, identifying problems,generating and evaluating alternatives, and developing plans.Planners are increasingly expected to adopt a moremulti-disciplinary approach, especially in light of the risingimportance of sustainability and environmental concerns. This bookpresents the fundamentals of transportation planning in amultidisciplinary context, giving readers a practical reference forday-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning softwarepackages Get up to date on the latest standards, recommendations, andcodes Developed by The Institute of Transportation Engineers, thisbook is the culmination of over seventy years of transportationplanning solutions, fully updated to reflect the needs of achanging society. For a comprehensive guide with practical answers,The Transportation Planning Handbook is an essentialreference.

Download or read book Methods to Analyze and Predict Interstate Travel Time Reliability written by Xiaoxiao Zhang and published by . This book was released on 2021 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Moving Ahead for Progress in the 21st Century Act (MAP-21) defined requirements for system reliability performance measures. Under MAP-21, state departments of transportation are responsible for reporting travel time reliability and for setting targets and showing progress toward those targets. In order to know how to improve travel time reliability and what to expect from investments in transportation infrastructure, these agencies need a better understanding of the factors that affect travel time reliability and methods to predict future travel time reliability. The purpose of this study was to quantify the factors influencing travel time reliability and investigate how to account for these factors in setting reliability targets and communicating progress. To achieve these objectives, this study developed models to estimate quantiles (the 50th, 80th, and 90th) of travel time distributions to quantify the effects of travel time reliability impact factors and predict select reliability measures. First, linear quantile mixed models (LQMMs) were built using both data maintained by the Virginia Department of Transportation (VDOT) and crowdsourced event data. Model results using the crowdsourced data were unstable and difficult to interpret because of data quality issues such as unbalanced spatial density, duplicate reporting, and inconsistent event classification because of individual observer bias. The results using VDOT-maintained data were more reliable and interpretable. Those models showed that frequencies of non-recurrent events, such as incidents and weather, were correlated with higher travel time percentiles. The LQMM was compared with the trend line approach, a common prediction method used in practice, and the results showed that LQMMs significantly improved the accuracy of predictions over the trend line approach based on mean absolute percent error. Generalized random forest (GRF) models were also tested as an alternative prediction method. GRF models improved the prediction accuracy over LQMMs for the 50th and 80th percentiles, but the accuracy was slightly worse for the 90th percentile. In addition, the GRF models could also reflect the impact of variables that were removed from LQMMs because of insignificance, such as the presence of safety service patrols. Before-after studies were conducted to illustrate the application of LQMMs and GRF models. LQMMs captured the changes in the 90th percentile travel times better, and GRF models captured the changes of level of travel time reliability better in most cases. GRF models were more sensitive to the reliability changes caused by non-recurrent events, such as incidents or work zones, and could reflect the impact of variables that were removed from LQMMs because of insignificance. The study recommends that VDOT use the GRF model for predicting travel time reliability on interstate highways. In addition, further research is recommended to extend the GRF models to meet the requirements of MAP-21 federal target setting.
