The MATSim (Multi-Agent Transport Simulation) software project was started around 2006 with the goal of generating traffic and congestion patterns by following individual synthetic travelers through their daily or weekly activity programme. It has since then evolved from a collection of stand-alone C++ programs to an integrated Java-based framework which is publicly hosted, open-source available, automatically regression tested. It is currently used by about 40 groups throughout the world. This book takes stock of the current status. The first part of the book gives an introduction to the most important concepts, with the intention of enabling a potential user to set up and run basic simulations. The second part of the book describes how the basic functionality can be extended, for example by adding schedule-based public transit, electric or autonomous cars, paratransit, or within-day replanning. For each extension, the text provides pointers to the additional documentation and to the code base. It is also discussed how people with appropriate Java programming skills can write their own extensions, and plug them into the MATSim core. The project has started from the basic idea that traffic is a consequence of human behavior, and thus humans and their behavior should be the starting point of all modelling, and with the intuition that when simulations with 100 million particles are possible in computational physics, then behavior-oriented simulations with 10 million travelers should be possible in travel behavior research. The initial implementations thus combined concepts from computational physics and complex adaptive systems with concepts from travel behavior research. The third part of the book looks at theoretical concepts that are able to describe important aspects of the simulation system; for example, under certain conditions the code becomes a Monte Carlo engine sampling from a discrete choice model. Another important aspect is the interpretation of the MATSim score as utility in the microeconomic sense, opening up a connection to benefit cost analysis. Finally, the book collects use cases as they have been undertaken with MATSim. All current users of MATSim were invited to submit their work, and many followed with sometimes crisp and short and sometimes longer contributions, always with pointers to additional references. We hope that the book will become an invitation to explore, to build and to extend agent-based modeling of travel behavior from the stable and well tested core of MATSim documented here.
Since 2000, there has been an exponential amount of research completed in the field of transport modelling thereby creating a need for an expanded and revised edition of this book. National transport models have taken on the new modelling methods and there have been theoretical and empirical advances in performance measurement. Coverage will include current demand methods, data issues, valuation, cost and performance, and updated traffic models. Supplementary case studies will illustrate how modelling can be applied to the study of the different transport modes and the infrastructures that support them.The second edition of this handbook will continue to be an essential reference for researchers and practitioners in the field. All contributions are by leading experts in their fields and there is extensive cross-referencing of subject matter. This book features expanded coverage on emerging trends and updated case studies. It addresses models for specific applications (i.e. parking, national traffic forecasting, public transport, urban freight movements, and logistics management).

Change the world one trip at a time. In this illuminating collection of stories and lessons from the road, acclaimed travel writer Rick Steves shares a powerful message that resonates now more than ever. With the world facing divisive and often frightening events, from Trump, Brexit, and Erdogan, to climate change, nativism, and populism, there's never been a more important time to travel. Rick believes the risks of travel are widely exaggerated, and that fear is for people who don't get out much. After years of living out of a suitcase, he still marvels at how different cultures find different truths to be self-evident. By sharing his experiences from Europe, Central America, Asia, and the Middle East, Rick shows how we can learn more about own country by viewing it from afar. With gripping stories from Rick's decades of exploration, this fully revised edition of Travel as a Political Act is an antidote to the current climate of xenophobia. When we travel thoughtfully, we bring back the most beautiful souvenir of all: a broader perspective on the world that we all call home. All royalties from the sale of Travel as a Political Act are donated to support the work of Bread for the World, a non-partisan organization working to end hunger at home and abroad.
The Office of the Assistant Secretary for Planning and Evaluation (ASPE), in partnership with other agencies and divisions of the United States Department of Health and Human Services, coordinates a portfolio of projects that build data capacity for conducting patient-centered outcomes research (PCOR). PCOR focuses on producing scientific evidence on the effectiveness of prevention and treatment options to inform the health care decisions of patients, families, and health care providers, taking into consideration the preferences, values, and questions patients face when making health care choices. ASPE asked the National Academies to appoint a consensus study committee to identify issues critical to the continued development of the data infrastructure for PCOR. Building Data Capacity for Patient-Centered Outcomes Research contains findings and conclusions in the areas that could benefit from being prioritized as part of ASPE's work, and offers input on strengthening the overall framework for building the data infrastructure over the coming years. The committee authoring this report also issued three interim reports, which summarized discussions from three workshops, and are included as appendices in the final report.
This document updates and expands the American Association of State Highway and Transportation Officials (AASHTO) User Benefit Analysis for Highways, also known as the Red Book. This AASHTO publication helps state and local transportation planning authorities evaluate the economic benefits of highway improvements. This update incorporates improvements in user-benefit calculation methods and, for the first time, provides guidance for evaluating important non-user impacts of highways. Previous editions of the Red Book provided guidance regarding user benefit measurement only. This update provides a framework for project evaluations that accurately account for both user and non-user benefits. The manual and accompanying CD-ROM provide a valuable resource for people who analyze the benefits and costs of highway projects.
Not another collection of checklists or tips on coupons or promotions, this practical guide teaches travelers — novice or seasoned — how to take advantage of travel opportunities by avoiding the typical tourist mentality. Author Tim Leffel shows readers how to bypass the traps that drive up expenses and find the best value, whether as a young backpacker or a wealthy retiree. Drawing on his own extensive experience (including three yearlong trips around the globe as well as his experience as an industry insider), the author also covers what steps to take and what resources to use to save money on travel and how to travel better — or more often — on a smaller budget. A dozen other notable travel writers and subject matter experts contribute sidebars on specific ways to save.
A transportation indicator is a measure of change over time in the transportation system or in its social, economic, environmental, or other effects. Two National Research Council (NRC) studies recommended, as a matter of high priority, that the Bureau of Transportation Statistics (BTS) in the U.S. Department of Transportation (USDOT) develop a consistent, easily understood, and useful set of key indicators of the transportation system. The NRC's Committee on National Statistics and its Transportation Research Board, which conducted these studies, convened a workshop on June 13, 2000. The purpose of the Workshop on Transportation Indicators was to discuss issues relating to transportation indicators and provide the Bureau of Transportation Statistics with new ideas for issues to address.
