Available in PDF, EPUB and Kindle. Book excerpt: This book contains selected peer-reviewed papers that were presented at the Fourth International Symposium on Transportation Network Reliability (INSTR) Conference held at the University of Minnesota July 22-23, 2010. International scholars, from a variety of disciplines--engineering, economics, geography, planning and transportation—offer varying perspectives on modeling and analysis of the reliability of transportation networks in order to illustrate both vulnerability to day-to-day and unpredictability variability and risk in travel, and demonstrates strategies for addressing those issues. The scope of the chapters includes all aspects of analysis and design to improve network reliability, specifically user perception of unreliability of public transport, public policy and reliability of travel times, the valuation and economics of reliability, network reliability modeling and estimation, travel behavior and vehicle routing under uncertainty, and risk evaluation and management for transportation networks. The book combines new methodologies and state of the art practice to model and address questions of network unreliability, making it of interest to both academics in transportation and engineering as well as policy-makers and practitioners.

Available in PDF, EPUB and Kindle. Book excerpt: The reliability of transportation networks has become an increasingly important issue as sustained economic growth and improvements to the quality of life around the world lead to increases in the value of time. Consequently, schedules and routes need to be able to accommodate the unexpected, like accidents, disasters or traffic flow fluctuations, with as little loss in operational efficiency as possible. Sources of unreliability include variation of demand and supply. It is widely expected that network reliability analysis will play a more important role in the planning, design and management of transportation facilities and networks in the future. This book is an outcome of the First International Symposium on Transport Network Reliability (INSTR), held at Kyoto in 2001, and consists of 24 selected papers. It covers various aspects of transport network reliability, such as definitions and methodological developments for reliability indices, behavioural analysis under uncertainty, evaluation methods for the disaster resistance of transport networks, and simulation/observation of travel time reliability.

This book was released on 2013-06-29 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each chapter in Equilibrium and Advanced Transportation Modelling develops a topic from basic concepts to the state-of-the-art, and beyond. All chapters relate to aspects of network equilibrium. Chapter One advocates the use of simulation models for the representation of traffic flow movements at the microscopic level. Chapter Two presents travel demand systems for generating trip matrices from activity-based models, taking into account the entire daily schedule of network users. Chapter Three examines equilibrium strategic choices adopted by the passengers of a congested transit system, carefully addressing line selection at boarding and transfer nodes. Chapter Four provides a critical appraisal of the traditional process that consists in sequentially performing the tasks of trip generation, trip distribution, mode split and assignment, and its impact on the practice of transportation planning. Chapter Five gives an insightful overview of stochastic assignment models, both in the static and dynamic cases. Chapters Six and Seven investigate the setting of tolls to improve traffic flow conditions in a congested transportation network. Chapter Eight provides a unifying framework for the analysis of multicriteria assignment models. In this chapter, available algorithms are summarized and an econometric perspective on the estimation of heterogeneous preferences is given. Chapter Nine surveys the use of hyperpaths in operations research and proposes a new paradigm of equilibrium in a capacitated network, with an application to transit assignment. Chapter Ten analyzes the transient states of a system moving towards equilibrium, using the mathematical framework of projected dynamical systems. Chapter Eleven discusses an in-depth survey of algorithms for solving shortest path problems, which are pervasive to any equilibrium algorithm. The chapter devotes special attention to the computation of dynamic shortest paths and to shortest hyperpaths. The final chapter considers operations research tools for reducing traffic congestion, in particular introducing an algorithm for solving a signal-setting problem formulated as a bilevel program.

Download or read book Routing Strategies for the Reliable and Efficient Utilization of Road Networks written by Samitha Samaranayake and published by . This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this dissertation aims to develop computationally tractable models and algorithms for the reliable and efficient utilization of capacity restricted transportation networks via route selection and demand redistribution, motivated by the fact that traffic congestion in road networks is a major problem in urban communities. Three related topics are considered, 1) route planning with reliability guarantees, 2) system optimal dynamic traffic assignment, and 3) controlling user equilibrium departure times. Route planning can in many practical settings require finding a route that is both fast and reliable. However, in most operational settings, only deterministic shortest paths are considered, and even when the link travel-times are known to be stochastic the common approach is to simply minimize the expected travel-time. This approach does not account for the variance of the travel-time and gives no reliability guarantees. In many cases, travelers have hard deadlines or are willing to sacrifice some extra travel-time for increased travel-time reliability, such as in commercial routing applications where delivery guarantees need to be met and perishables need to be delivered on time. The research presented in this dissertation develops fast computation techniques for the reliable routing problem known as the stochastic on-time arrival (SOTA) problem, which provides a routing strategy that maximizes the probability of arriving at the destination within a fixed time budget. Selfish user optimal routing strategies can, however, lead to very inefficient traffic equilibria in congested traffic networks. This "Price of Anarchy" can be mitigated using system optimal coordinated routing algorithms. The dissertation considers the system optimal dynamic traffic assignment problem when only a subset of the network agents can be centrally coordinated. A road traffic dynamics model is developed based on the Lighthill-Williams-Richards partial differential equation and a corresponding multi-commodity junction solver. Full Lagrangian paths are assumed to be known for the controllable agents, while only the aggregate split ratios are required for the non-controllable (selfish) agents. The resulting non-linear optimal control problem is solved efficiently using the discrete adjoint method. Spill-back from under-capacitated off-ramps is one of the major causes of congestion during the morning commute. This spill-back induces a capacity drop on the freeway, which then creates a bottleneck for the mainline traffic that is passing by the off-ramp. Therefore, influencing the flow distribution of the vehicles that exit the freeway at the off-ramp can improve the throughput of freeway vehicles that pass this junction. The dissertation studies the generalized morning commute problem where vehicles exiting the freeway at the under-capacitated off-ramp have a fixed desired arrival time and a corresponding equilibrium departure time schedule, and presents strategies to manipulated this equilibrium to maximize throughput on the freeway via incentives or tolls.

Download or read book Game Theoretic Analysis of Congestion, Safety and Security written by Kjell Hausken and published by Springer. This book was released on 2014-12-31 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maximizing reader insights into the roles of intelligent agents in networks, air traffic and emergency departments, this volume focuses on congestion in systems where safety and security are at stake, devoting special attention to applying game theoretic analysis of congestion to: protocols in wired and wireless networks; power generation, air transportation and emergency department overcrowding. Reviewing exhaustively the key recent research into the interactions between game theory, excessive crowding, and safety and security elements, this book establishes a new research angle by illustrating linkages between the different research approaches and serves to lay the foundations for subsequent analysis. Congestion (excessive crowding) is defined in this work as all kinds of flows; e.g., road/sea/air traffic, people, data, information, water, electricity, and organisms. Analysing systems where congestion occurs – which may be in parallel, series, interlinked, or interdependent, with flows one way or both ways – this book puts forward new congestion models, breaking new ground by introducing game theory and safety/security into proceedings. Addressing the multiple actors who may hold different concerns regarding system reliability; e.g. one or several terrorists, a government, various local or regional government agencies, or others with stakes for or against system reliability, this book describes how governments and authorities may have the tools to handle congestion, but that these tools need to be improved whilst additionally ensuring safety and security against various threats. This game-theoretic analysis sets this two volume book apart from the current congestion literature and ensures that the work will be of use to postgraduates, researchers, 3rd/4th-year undergraduates, policy makers, and practitioners.

Available in PDF, EPUB and Kindle. Book excerpt: The interest in the mathematical modeling of transportation systems stems from the need to predict how people might make use of new or improved transport infrastruc ture in order to evaluate the benefit of the required investments. To this end it is necessary to build models of the demand for transportation and models that de termine the way in which people who travel use the transportation network. If such models may be constructed and their validity reasonably assured, then the predic tion of the traffic flows on future and present transportation links may be carried out by simulating future situations and then evaluating the potential benefits of alternative improvement projects. In the attempts that were made to construct mathematical models of transportation networks, the notion of equilibrium plays a central role. Suppose that the demand for transportation, that is, the number of trips that occur between the - rious origins and destinations is known. Then it is necessary to determine how these trips are attracted to the alternative routes available between origins and destinations. Knight (1924), gave a simple and intuitively clear description of the behaviour of road traffic under conditions of congestion.
