Already the market leader in the field, Modelling Transport has become still more indispensible following a thorough and detailed update. Enhancements include two entirely new chapters on modelling for private sector projects and on activity-based modelling; a new section on dynamic assignment and micro-simulation; and sizeable updates to sections on disaggregate modelling and stated preference design and analysis. It also tackles topical issues such as valuation of externalities and the role of GPS in travel time surveys. Providing unrivalled depth and breadth of coverage, each topic is approached as a modelling exercise with discussion of the roles of theory, data, model specification, estimation, validation and application. The authors present the state of the art and its practical application in a pedagogic manner, easily understandable to both students and practitioners. Follows on from the highly successful third edition universally acknowledged as the leading text on transport modelling techniques and applications Includes two new chapters on modelling for private sector projects and activity based modeling, and numerous updates to existing chapters Incorporates treatment of recent issues and concerns like risk analysis and the dynamic interaction between land use and transport Provides comprehensive and rigorous information and guidance, enabling readers to make practical use of every available technique Relates the topics to new external factors and technologies such as global warming, valuation of externalities and global positioning systems (GPS).

Offering an outstanding exploration of the state of the art, this practical, applications-oriented text/reference presents the most important transport modeling techniques in a form accessible to students and professionals alike. Bridging the gap between theoretical and ``recipe'' publications, it emphasizes a number of key topics in the field including the practical importance of theoretical consistency; the issues of data and specification errors in modeling, their relative importance, and methods for handling them; the key role played by the decision-making context in the choice of the most appropriate modeling tool; the advantages of variable resolution modeling; and the need for a monitoring function, relying on regular data collection and updates of forecasts and models so that courses of action can be adapted to a changing environment. Included are examples and exercises useful for actual laboratory fieldwork.

Approaches the subject from the perspective of a modelling exercise discussing the role of theory, data, model specification in its broadest sense, model estimation, validation, and forecasting. Examines the practical constraints to transport modelling for planning and policy making, particularly in view of the limitations of current formal analytical techniques, and the nature and quality of available data. The main thrust is to provide enough information and guidance so readers can actually go and use each technique in the field. In this edition material on Stated-Preference techniques has been strengthened.

Freight Transport Modelling is a unique new reference book that provides insight into the state-of-the-art of freight modelling. Focusing on models used to support public transport policy analysis, Freight Transport Modelling systematically introduces the latest freight transport modelling approaches and describes the main methods and techniques used to arrive at operational models. As freight transport has grown exponentially in recent decades, policymakers now need to include freight flows in quantitative evaluations of transport systems. Whereas early freight modelling practice was inspired by passenger transport models, by now it has developed its separate stream of methods and techniques inspired by disciplines such as economic geography and supply chain management. Besides summarizing the latest achievements in fundamental research, this book describes the state of practice and advises practitioners on how to cope with typical challenges such as limitations in data availability. Uniquely focused book exploring the key issues and logistics of freight transport modelling Highlights the latest approaches and describes the main methods and techniques used to arrive at operational models Summarizes fundamental research into freight transport modeling, as well as current practices and advice for practitioners facing day-to-day challenges

This book shows how transit assignment models can be used to describe and predict the patterns of network patronage in public transport systems. It provides a fundamental technical tool that can be employed in the process of designing, implementing and evaluating measures and/or policies to improve the current state of transport systems within given financial, technical and social constraints. The book offers a unique methodological contribution to the field of transit assignment because, moving beyond “traditional” models, it describes more evolved variants that can reproduce:• intermodal networks with high- and low-frequency services;• realistic behavioural hypotheses underpinning route choice;• time dependency in frequency-based models; and• assumptions about the knowledge that users have of network conditionsthat are consistent with the present and future level of information that intelligent transport systems (ITS) can provide. The book also considers the practical perspective of practitioners and public transport operators who need to model and manage transit systems; for example, the role of ITS is explained with regard to their potential in data collection for modelling purposes and validation techniques, as well as with regard to the additional data on network patronage and passengers’ preferences that influences the network-management and control strategies implemented. In addition, it explains how the different aspects of network operations can be incorporated in traditional models and identifies the advantages and disadvantages of doing so. Lastly, the book provides practical information on state-of-the-art implementations of the different models and the commercial packages that are currently available for transit modelling. Showcasing original work done under the aegis of the COST Action TU1004 (TransITS), the book provides a broad readership, ranging from Master and PhD students to researchers and from policy makers to practitioners, with a comprehensive tool for understanding transit assignment models.

'This collection in honor of David Boyce contains genuinely interesting and quality papers that reflect the diversity of interests of the honoree. David Boyce has made a number of significant contributions at the interface of transportation and regional science. He has been a pioneer of injecting rigor and consistency into spatial analysis. The papers here both reflect the ethos of this copious body of analysis and take it further in extensions and applications. It will prove to be an enduring source of ideas and insight.' - Kenneth Button, George Mason University, US

Diagenetic Models and Their Implementation

Modelling Transport and Reactions in Aquatic Sediments

The study of sedimentary chemistry and its associated processes is becoming increasingly mathematical. There is a growing desire to gain a quantitative understand of the reasons for the natural chemical changes observed in sediments as they are buried. Past textbooks have not emphasized the steps necessary to develop transport-reaction (diagenetic) models themselves nor methods for their solution. This book attempts to present a detailed account of model formulation by explaining some useful solution techniques. The choice of material illustrates methods that are simple to understand and implement, yet powerful enough to attack even the most complicated diagenetic problems. The cited computer programs are accessible on the Internet.
