Download or read book Traffic Flow Dynamics written by Martin Treiber and published by Springer Science & Business Media. This book was released on 2012-10-11 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2023-11-27T00:00:00+01:00 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past nine decades, the field of traffic flow studies has witnessed remarkable advancements driven by empirical data. These data have illuminated traffic phenomena like breakdowns, oscillations, and hysteresis. However, despite these strides, the intricate nature of traffic flow and its underlying mechanisms remain subjects of ongoing debate and incomplete comprehension. Robert Herman, the pioneering figure in transportation science, firmly believed in the experimental essence of traffic theory. Unlike conventional practices of collecting limited traffic flow data, conducting traffic experiments empowers control of flow composition and rate, minimizes interference from complex variables, and facilitates the discovery of fundamental characteristics and mechanisms of traffic flow. In alignment with Herman’s conviction, the authors of this book undertook a series of experimental and modeling studies to delve into the intricacies of traffic flow evolution through the lens of car-following dynamics. Rooted in systems science and engineering theory, this book commences with experimental exploration of traffic flow. Employing methods to unearth individual decision-making mechanisms, the evolutionary patterns of group behavior, and their interconnectedness, theoretical models are employed to bridge micro-mechanisms with macro-phenomena. This approach introduces innovative ideas and methods, fostering the refined development of urban traffic behavior and management theory. It makes vital contributions in unraveling driver behavior and the evolution of road traffic flow, transcending conventional theories, and addressing globally recognized transportation challenges. Ultimately, it plays a pivotal role in advancing modern traffic flow theory that aligns with real-world complexities.

Book Synopsis Intersections Control and Safety by : Antonio Pratelli
Download or read book Intersections Control and Safety written by Antonio Pratelli and published by WIT Press. This book was released on 2013-05-22 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting off a new series on Transport Systems and Traffic Engineering the book aims to help bridge the gap between research and practice, encouraging a critical dialogue in different, specific, subjects spanning innovation, development and technology transfer. Those who offer innovation often do not meet the immediate needs of practitioners, especially in the traditional field of civil engineering. Still, the adequate diffusion of research results and wisdom derived from practical experience are crucial to both theoretical underpinnings and technical applications.The papers forming this book are devoted to intersection control and safety and have been selected bearing in mind the criteria stated above. That is, these papers provide both scholarly contribution as well as vision for application.As a general rule, about one-third of all highway crashes happen at intersections. This rule holds for many different countries. Intersection crashes also represent a significant portion of serious injury crashes, and by right are receiving considerable attention from researchers and practitioners alike. This book is therefore devoted to relevant safety aspects of road intersections and innovative features in design and operations that may address the intersection crash problem. The thirteen papers are more or less equally devoted to roundabouts and signals. These papers cover many of the most recent and emerging issues related to intersection control and safety. Topics range from design details to driver perception, from pedestrians behaviour to signal timing, and from capacity models to red-light running. The book will be useful for those wishing to expand their knowledge of this ever important subject area.

Book Synopsis Modeling Stochastic Human-driver Car Following Behavior in Oscillatory Traffic Conditions by : Raphael Stern
Download or read book Modeling Stochastic Human-driver Car Following Behavior in Oscillatory Traffic Conditions written by Raphael Stern and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurately modeling the realistic and unstable traffic dynamics of human-driven traffic flow is crucial to being able to understand how traffic dynamics evolve, and how new agents such as autonomous vehicles might influence traffic flow stability. This work is motivated by a recent dataset that allows us to calibrate accurate models, specifically in conditions when traffic waves arise. Three microscopic car-following models are calibrated using a microscopic vehicle trajectory dataset that is collected with the intent of capturing oscillatory driving conditions. For each model, five traffic flow metrics are constructed to compare the flow-level characteristics of the simulated traffic with experimental data.

Book Synopsis Analysis, Modeling and Simulation of Micro Scale Traffic Dynamics Under Different Driving Environments by : Hui Deng

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Individual driving behavior, such as anticipation, risk-taking and cooperative lane change, has significant impact on overall traffic flow characteristics and highway performance. It contributes to various traffic flow phenomena, including platooning, capacity drop and traffic oscillations. A good understanding of driving behavior under different driving environments, such as curved roads, lane-drops, merges and diverges, and platooning enabled by vehicle to vehicle communication, can help us design safer roads, and safer and more efficient autonomous or semi-autonomous driving vehicles. New car following models have been developed to capture the empirical observed anticipation and risk-taking driving behavior, and applied to investigate how anticipation and risk-taking may lead to different traffic flow phenomena and influence highway capacity and safety. Considering gap anticipation, full range traffic conditions can be reproduced, including free-flow, congestion and traffic jam under fixed and moving bottleneck, realistic flow capacities and fundamental diagrams with different levels of anticipation, as well as platoon driving when gap anticipation dependents on the gap. The effect of risk-taking on traffic safety is studied with a collision-possible car following model considering driver anticipation. Risk-taking leads to traffic oscillations and potential collision hazards when traffic is not stable. Longer length of view field can improve traffic safety, and large numbers of vehicle crashes happen when view field length is shorter than given threshold. Merge traffic dynamic has been studied by simulating of cooperative lane change, and drivers' merge location choice is studied to show its impact on traffic oscillations near merging junction. A simplified lane change cooperation strategy is developed and integrated with optimal speed car following logic to capture cooperative lane change behavior in merge junctions. This model can reproduce reasonable merge ratio, capacity drop, turn taking merging behavior and stop and go traffic at merge bottleneck. Lane change incentive and main lane traffic condition affect drivers' lane change behavior and leads to different merge location choice. Microscopic and macroscopic traffic simulation show merge location choice contributes to the formation of stop-and-go waves near merging junctions and the period of these waves are closely related to the distance between the two dominant merging locations. Theoretical and data analysis are used to reveal the correlation between drivers' anticipation, relaxation behavior and traffic hysteresis. Through an analysis of the trajectory data from NGSIM and a theoretical analysis of car-following models, it is revealed that traffic hysteresis is generated by an imbalance in driver relaxation and anticipation. By changing the strength of relaxation and anticipation, we are able to reproduce positive, negative and double hysteresis loops, as well as aggressive and timid driving behavior. It is further shown that the relative positions of acceleration and deceleration phase with respect to the equilibrium state is not unique and are determined by the comparative strength of relaxation and anticipation in different traffic conditions. This study suggests that traffic hysteresis can be suppressed by balancing driver relaxation and anticipation, and stop-and-go traffic can be smoothed by eliminating aggressive driving in congested traffic. A three-mode vehicle control law is proposed for ACC (Adaptive Cruise Control) and CACC (Cooperative Adaptive Cruise Control) and implemented in VENTOS (VEhicular NeTwork Open source Simulator). Traffic hysteresis and stability of studied both analytically and using VENTOS simulation. The ability of ACC/CACC to improve highway safety and eliminating traffic hysteresis is verified by traffic simulation under critical traffic conditions, including realistic stop-and-go traffic and worst case stopping. Through analytical approaches and simulation, we have demonstrated the stability and robustness of our proposed ACC/CACC control system against sensor measurement errors and lossy wireless communication links which is required to implement the CACC control logic. The benefit of wireless communication, even with some lossy links, is significant in ensuring stream stability and performance.
