Book Description
This monograph provides an extended overview of modelling and control approaches for freeway traffic systems, moving from the early methods to the most recent scientific results and field implementations. The concepts of green traffic systems and smart mobility are addressed in the book, since a modern freeway traffic management system should be designed to be sustainable. Future perspectives on freeway traffic control are also analysed and discussed with reference to the most recent technological advancements The most widespread modelling and control techniques for freeway traffic systems are treated with mathematical rigour, but also discussed with reference to their performance assessment and to the expected impact of their practical usage in real traffic systems. In order to make the book accessible to readers of different backgrounds, some fundamental aspects of traffic theory as well as some basic control concepts, useful for better understanding the addressed topics, are provided in the book. This monograph can be used as a textbook for courses on transport engineering, traffic management and control. It is also addressed to experts working in traffic monitoring and control areas and to researchers, technicians and practitioners of both transportation and control engineering. The authors’ systematic vision of traffic modelling and control methods developed over decades makes the book a valuable survey resource for freeway traffic managers, freeway stakeholders and transportation public authorities with professional interests in freeway traffic systems. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

Author: Robert Gordon
Publisher: Springer Science & Business Media
ISBN: 1441907335
Category : Technology & Engineering
Languages : en
Pages : 219
Book Description
Intelligent Freeway Transportation Systems: Functional Design focuses on the efficient use of resources in the design of ITS. It discusses the principles of top down design starting with objectives and requirements, and provides guidance for the development and evaluation of functional design alternatives according to cost effectiveness principles. It shows how transportation planning principles such as Wardrop’s Laws and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types are provided. Application factors to identify device deployment densities (e.g. number of detectors per mile) as a function of traffic conditions are provided, as are evaluation models for evaluating the benefits of design alternatives based on traffic conditions. Design guidance and benefits evaluation include the following functions: (1) Non-recurrent congestion – Improvement of incident clearance time, (2) Non recurrent congestion – Incident information to motorists, (3) Recurrent congestion – Information to motorists, (4) Ramp metering, (5) Motorist service patrols.

Book Description
Intelligent Transportation Systems: Functional Design for Economical and Efficient Traffic Management provides practical guidance on the efficient use of resources in the design of ITS. The author explains how functional design alternatives can meet project objectives and requirements with optimal cost effectiveness and clarifies how transportation planning and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types, determining device deployment densities and determining the best placement of CCTV cameras and message signs are provided, as are models for evaluating the benefits of design alternatives based on traffic conditions. Readers will learn how to reduce recurrent congestion, improve incident clearance time in non-recurrent congestion, provide real-time incident information to motorists, and leverage transportation management center data for lane control through important new active transportation and demand management (ATDM) methods. Finally, the author examines exciting developments in connected vehicle technologies, exploring their potential to greatly improve safety, mobility and energy efficiency. This resource will greatly benefit all ITS designers and managers and is of pivotal importance for operating agencies performing evaluations to justify operational funding and system expansions.

Advanced Freeway System Ramp Metering Strategies for Texas
Author: Carroll J. Messer
Publisher:
ISBN:
Category : Electronic traffic controls
Languages : en
Pages : 114
Book Description
Freeway ramp metering systems have been used to improve urban freeway flow. However, control strategies must be properly adjusted to account for ramp queues overflowing onto surface streets and provide equitable on-ramp control during various operating periods. An improved solution can be obtained by optimizing this problem simultaneously for a group of time slices. This study identifies and examines a microcomputer-based optimization scheme that can assist in developing efficient freeway control strategies for on-line freeway surveillance and control. A multi-level freeway control structure is employed for which ramp metering control algorithms are developed for each level of control. Flow-based and lane occupancy-based system algorithms are presented. Detailed data file requirements are provided for each control level. A microcomputer prototype, or laboratory test version of the system level, will be described in a companion project report.

Development and Evaluation of Selected Mobility Applications for VII
Author: Steven E. Shladover
Publisher:
ISBN:
Category : Highway communications
Languages : en
Pages : 98
Book Description
"This report describes the development of two of the three mobility applications that PATH has developed and evaluated under the sponsorship of the FHWA Exploratory Advanced Research Program, with cost share funding provided by Caltrans Contract 65A0351. These applications are intended to use DSRC wireless communications among vehicles and between vehicles and the roadway infrastructure to improve mobility on limited-access highways. The first application combines ramp metering with variable speed limits to enhance control of traffic so that traffic flow breakdowns can be deferred or avoided at bottleneck locations. The second application uses vehicle-vehicle communication to improve the performance of adaptive cruise control systems so that they can operate safely with smaller longitudinal gaps and vehicle-roadside communication to provide adjustments to their set speed and gap settings to adapt to changes in local traffic conditions."--Abstract, p. i.

Empirical Study of Ramp Metering and Capacity
Author: Michael James Cassidy
Publisher:
ISBN:
Category : Express highway interchanges
Languages : en
Pages : 52
Book Description
This report describes traffic details measured at a freeway merge before and after it became a bottleneck during six observation days. Findings indicate that flows departing this merge can be made substantially higher by metering the on-ramp to restrict the rate its vehicles enter the freeway. It follows then that ramp meters can postpone a bottleneck's activation.
