Book Dynamic Route Guidance Algorithms for Robust Roadway Networks

Download or read book Dynamic Route Guidance Algorithms for Robust Roadway Networks written by Agop Koulakezian and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This Thesis focuses on developing robust dynamic route guidance algorithms to reduce traffic congestion in roadway networks. While recurring traffic congestion is normally the focus in planning and investment decisions, almost half of traffic congestion is caused by non-recurring traffic disturbances, primarily caused by incidents, vehicle breakdowns, extreme weather events, etc. In order to reduce traffic congestion, we focus on the problem of understanding the effect of traffic disturbances and reducing their impact on roadway networks. We introduce a systematic framework for defining the context of robustness based on the severity, frequency and predictability of traffic disturbances and for developing a robust design for roadway networks based on network design goals. We also present methods to speed up traffic assignment algorithms through compiler optimizations and parallelism, to efficiently measure the effect of traffic disturbances, and enable real-time ITS applications including dynamic route guidance systems. Next, we introduce a hybrid metric for measuring robustness in a roadway network by extending the shortest-path betweenness metric from network science, and augmenting it with links weights based on dynamic traffic flow metrics. Finally, we implement a robust dynamic traffic assignment algorithm for roadway networks based on this metric and test it on a large-scale calibrated network model for the Greater Toronto Area. Performance results show that the robust traffic assignment algorithm reduces vehicle travel times compared to existing traffic assignment algorithms, with and without the presence of disturbances in the form of traffic incidents. This makes a strong case for traffic planners and operators to use robust dynamic route guidance systems within actual implementations of real-time ITS strategies to help proactively alleviate traffic congestion due to disturbances.

Book Urban Traffic Networks

Download or read book Urban Traffic Networks written by Nathan H. Gartner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems of urban traffic in the industrially developed countries have been at the top of the priority list for a long time. While making a critical contribution to the economic well being of those countries, transportation systems in general and highway traffic in particular, also have detrimental effects which are evident in excessive congestion, high rates of accidents and severe pollution problems. Scientists from different disciplines have played an important role in the development and refinement of the tools needed for the planning, analysis, and control of urban traffic networks. In the past several years, there were particularly rapid advances in two areas that affect urban traffic: 1. Modeling of traffic flows in urban networks and the prediction of the resulting equilibrium conditions; 2. Technology for communication with the driver and the ability to guide him, by providing him with useful, relevant and updated information, to his desired destination.

Book The Evolution of Travel Time Information Systems

Download or read book The Evolution of Travel Time Information Systems written by Margarita Martínez-Díaz and published by Springer Nature. 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 Modeling Dynamic Transportation Networks

Download or read book Modeling Dynamic Transportation Networks written by Bin Ran and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book seeks to summarize our recent progress in dynamic trans portation network modeling. It concentrates on ideal dynamic network models based on actual travel times and their corresponding solution algorithms. In contrast, our first book DynamIc Urban Transportation Network Models - The ory and Implications for Intelligent Vehicle-Hzghway Systems (Springer-Verlag, 1994) focused on instantaneous dynamic network models. Comparing the two books, the major differences can be summarized as follows: 1. This book uses the variational inequality problem as the basic formulation approach and considers the optimal control problem as a subproblem for solution purposes. The former book used optimal control theory as the basic formulation approach, which caused critical problems in some circumstances. 2. This book focuses on ideal dynamic network models based on actual travel times. The former book focused on instantaneous dynamic network models based on currently prevailing travel times. 3. This book formulates a stochastic dynamic route choice model which can utilize any possible route choice distribution function instead of only the logit function. 4. This book reformulates the bilevel problem of combined departure time/ route choice as a one-level variational inequality. 5. Finally, a set of problems is provided for classroom use. In addition, this book offers comprehensive insights into the complexity and challenge of applying these dynamic network models to Intelligent Trans portation Systems (ITS). Nevertheless, the models in this text are not yet fully evaluated and are subject to revision based on future research.
