This book was released on 2024-10-23 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: As transport networks become more congested, there is a growing need to adopt policies that manage demand and make full use of existing assets. Advances in information technology are now such that intelligent transportation systems (ITS) offer real potential to meet this challenge by monitoring current conditions, predicting what might happen in the future, and providing the means to manage transport proactively and on an area-wide basis. Modeling and Simulation of Intelligent Transportation Systems provides engineers, professionals, and researchers an intuitive appreciation for ITS theory, related sensor technologies, and other practical applications, including traffic management, safety, design optimization, and sustainability. Provides the theory and practical applications of Intelligent Transport Theory which will be helpful as highway construction recedes as a sustainable long-term solution. Includes several case studies that illustrate the concepts presented throughout.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Today’s urban transportation networks accommodate large flows of both non-motorized and motorized traffic. The traffic dynamics between users is increasingly complex, thus the study of flows, performance and safety of facilities is critical. Current transportation networks rely on evidence-based planning and design, and traffic management and control systems. In this context, accurate monitoring of non-motorized transportation networks, in particular cycling, is crucial. The general objective of this thesis is to improve existing methods to automatically detect bicycle count anomalies and extrapolate volumes as well as to investigate the relationship between volumes, speed, and safety outcomes. The particular objectives of this thesis are to: i) develop a novel methodology for anomaly detection and interpolation of continuous bicycle count data, ii) improve existing methods to estimate average annual daily bicyclists with confidence intervals through extrapolation of short-term bicycle counts using reference site data, iii) investigate the relations between basic cycling traffic parameters on protected cycling infrastructure using empirical traffic flow data from bicycle facilities in Montreal, and iv) present a methodological framework for semi-automated video analysis of pedestrian-cyclist interactions at intersections in non-motorized shared space and estimate risk in a case study of the McGill Campus.The work from the first part of the thesis develops and tests methods that automatically detect bicycle count anomalies and extrapolate volumes of short-term counts. With the tool developed, anomalies in reference bike counts are identified and interpolated and the validated data is used to extrapolate short-term counts to generate accurate average annual daily bicyclists (AADB) estimations. In the second part of the thesis, the relationship between volumes, speed, and safety outcomes are investigated in non-motorized spaces. Firstly, preliminary work indicates a statistically significant reduction in bicycle speeds during peak periods as flow increases. Secondly, a framework for a safety assessment of pedestrian-cyclist interactions in shared space is developed and applied to the McGill campus, demonstrating a relatively low risk to pedestrians.The combined work from the first two chapters forms a methodology for monitoring bicycle facilities across a city or region. Future work includes testing the validation and interpolation tool developed in Chapter Two and the quality measure of short-term count extrapolations, developed in Chapter Three, with larger datasets. With sufficient AADB estimates from point sensors and cyclist trip GPS smartphone data from a sample of cyclists, an AADB model for all elements across a road network can be generated. Future work from the second part of the thesis includes extended testing with additional data to complement exploratory work on speed-flow relationships to develop cycling facility capacity models. The safety methodology, developed in Chapter 5, could be explored on a variety of conflict types, assessing their relative risk in different environments, particularly in shared space"--

Download or read book Traffic Flow Dynamics written by Martin Treiber and published by Springer Science & Business Media. This book was released on 2012-10-10 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.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation investigates the design and analysis of vehicular and pedestrian models. A type of vehicular model is developed both to offer novel contributions to vehicle behavior modeling as well as to use as a tool to learn how to create an even more complex behavioral model of pedestrian movement. First, the current state of modeling is investigated including purely behavioral studies and engineering modeling techniques. Behavioral studies are drawn largely from the field of urban affairs and planning while engineering modeling methods are drawn from civil engineering, mathematics, and computer science. Second, a model of vehicular traffic is constructed by first implementing existing work in software. Existing work focuses on single lane traffic, so we next extend the model to support lane changing in multiple lanes. The new mathematical rules are implemented in software and effects of lane changing then studied. The model contributes new capabilities to the field and provides experience to next create a more complex pedestrian model. Third, an algorithmic model of pedestrian movement is created. At its simplest level, steering rules are used that are drawn from the literature. New rules and models are created to support groups and simple social interaction. Learning and memory are then modeled so that simulated pedestrians are human-like in ways that have an effect on congestion. Fourth, software is developed that implements the model. While the model offers a means, i.e., function parameters, for calibration, an implementation must exist to take advantage of that. The software is designed using an object-oriented approach in conjunction with agent based modeling. A pedestrian is an object and agent, learns, has memory, follows its schedule, and moves in, affects and is affected by its environment, and explores the environment. Results from the calibrated software show that the model produces reliable results for situations where the modeled behavior is typical. Contributions to transportation engineering include the vehicular and especially the pedestrian model. Proof of concept software implementation shows the utility of the models and how they can be used to ease and improve design of vehicular and pedestrian areas.
