This textbook provides a comprehensive and instructive coverage of vehicular traffic flow dynamics and modeling. It makes this fascinating interdisciplinary topic, which to date was only documented in parts by specialized monographs, accessible to a broad readership. Numerous figures and problems with solutions help the reader to quickly understand and practice the presented concepts. This book is targeted at students of physics and traffic engineering and, more generally, also at students and professionals in computer science, mathematics, and interdisciplinary topics. It also offers material for project work in programming and simulation at college and university level. The main part, after presenting different categories of traffic data, is devoted to a mathematical description of the dynamics of traffic flow, covering macroscopic models which describe traffic in terms of density, as well as microscopic many-particle models in which each particle corresponds to a vehicle and its driver. Focus chapters on traffic instabilities and model calibration/validation present these topics in a novel and systematic way. Finally, the theoretical framework is shown at work in selected applications such as traffic-state and travel-time estimation, intelligent transportation systems, traffic operations management, and a detailed physics-based model for fuel consumption and emissions.

During the last decade physicists, engineers and computer scientists have joined in an enormously fruitful dialogue about traffic and granular flow. Cars and sand grains have in common, that they interact irreversibly, which is the reason for similar jamming phenomena. The main difference is that car drivers choose their destination and route individually, while grains follow external driving forces. This book gives an overview about the progress in modelling, computer simulation, experiments and field observations, which was reached within the last two years. The contributions are based on the International Workshop Traffic and Granular Flow '01, which took place in Nagoya, 15 - 17 October 2001. Topics include a critical classification of models for highway traffic, new technological applications, friction and arching phenomena in pedestrian traffic, scale free networks and internet traffic, instabilities and fluctuations in avalanches and granular pipe flow.

The purpose of this report is to summarize the research activities that were performed during the first year of this research project. In conducting this research, the research team split into several independent groups, each focusing on different aspects of the problem. One group has been focused on using weather and traffic flow conditions as predictors of incident conditions. Their activities are summarized in Chapter II. Other groups have been focused on developing models for producing short-term forecasts of potential congestion, using current measured traffic conditions. The results of these activities are summarized in Chapter III. Finally, the authors are beginning the process of developing a prototype tool that operators can use in a control center to display forecasted conditions. The beginnings of a high-level, functional specification for the tool are provided in Chapter IV.

The understanding of empirical traf?c congestion occurring on unsignalized mul- lane highways and freeways is a key for effective traf?c management, control, or- nization, and other applications of transportation engineering. However, the traf?c ?ow theories and models that dominate up to now in transportation research journals and teaching programs of most universities cannot explain either traf?c breakdown or most features of the resulting congested patterns. These theories are also the - sis of most dynamic traf?c assignment models and freeway traf?c control methods, which therefore are not consistent with features of real traf?c. For this reason, the author introduced an alternative traf?c ?ow theory called three-phase traf?c theory, which can predict and explain the empirical spatiot- poral features of traf?c breakdown and the resulting traf?c congestion. A previous book “The Physics of Traf?c” (Springer, Berlin, 2004) presented a discussion of the empirical spatiotemporal features of congested traf?c patterns and of three-phase traf?c theory as well as their engineering applications. Rather than a comprehensive analysis of empirical and theoretical results in the ?eld, the present book includes no more empirical and theoretical results than are necessary for the understanding of vehicular traf?c on unsignalized multi-lane roads. The main objectives of the book are to present an “elementary” traf?c ?ow theory and control methods as well as to show links between three-phase traf?c t- ory and earlier traf?c ?ow theories. The need for such a book follows from many commentsofcolleaguesmadeafterpublicationofthebook“ThePhysicsofTraf?c”.

This research consists of four studies aimed at enhancing traffic safety. These studies employ innovative approaches and model frameworks based on duration models. The first study focuses on Work Zone Intrusion Alert Systems (WZIAS) and explores their component layout and impact on work zone safety. By analyzing the duration between work zone intrusion and crashes, this study identifies critical factors contributing to work zone crashes when WZIAS are in use. The study concludes by offering recommendations to optimize WZIAS effectiveness, including potential adjustments to existing work zone guidelines. The second study addresses the limitations of duration models in handling time-varying factors and their inability to support real-time predictive modeling. It introduces a novel duration-based model framework capable of accommodating dynamic covariates for proactive crash prediction modeling. This approach involves discretizing the time between crashes into forecasting epochs. The study explores various sampling methods to address computational challenges arising from increased data size due to forecasting epochs. A 25% epoch-level sample is found effective for computational efficiency without sacrificing accuracy. The third study extends the duration-based crash prediction framework, to develop a novel approach for predicting crash and severity simultaneously. The study further seeks to strike a balance between model performance and estimation time. Findings suggest that a 15% sample drawn at the epoch level provides an efficient compromise. Stability analysis of predictor variables sheds light on their reliability across different samples. Variables such as Time of day (Early afternoon), Weather condition, Lighting condition (Daytime), Illumination, and Volume require larger samples for more accurate coefficient estimation. Conversely, Time of day (Early morning, Late morning, Late afternoon), Lighting condition (Dark lighted), Terrain, Land use, Number of lanes, and Speed converge towards true estimates with small incremental increases in sample size. The fourth study employs the duration-based proactive crash prediction framework to showcase its versatility and identify the predictors of speeding events in work zones. The model's validity is tested, with higher accuracy observed for speeding events occurring with shorter durations between consecutive occurrences. The study demonstrates how the framework can help transportation agencies identify high-risk highway segments and implement safety measures proactively.
