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.

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.

"Reliability of transport, especially the ability to reach a destination within a certain amount of time, is a regular concern of travelers and shippers. The definition of reliability used in this research is how travel time varies over time. The variability can apply to the travel times observed over a road segment during a specific time slice (e.g., 3 to 6 p.m.) over a fairly long period of time, say a year. The variability can also pertain to the travel times of repeated trips made by a person or a truck between a given origin and destination. Agencies are increasingly aware of the issue of reliability, although the transportation industry as a whole as yet lacks a firm understanding of the causes and solutions to failures of reliability. As the agenda for the SHRP 2 research on travel time reliability took shape, it became clear a fundamental study was required to be able to talk about travel time reliability in a meaningful way"--Foreword.
