Intelligent Transportation Systems (ITS) have been developed to help relieve traffic congestion and improve safety on highways. Work zones are key areas to deploy ITS because of the high risk of congestion and accidents due to lane closures. This thesis developed a methodology for evaluating the effectiveness of ITS in work zones. Past studies have not consistently used all necessary performance measures in their evaluations such as diversion, delay, queue lengths, accident rates, and various speed measurements. This thesis includes a comprehensive literature review on ITS in work zones, a general framework for evaluating work zone ITS deployments, application of the developed framework to I-70 and I-44 work zones, and a benefit-cost analysis to estimate the monetized ITS benefits. I-70 had a benefit-cost ratio of 5.1 to 1 if all of the cost of permanent equipment is included and 19.8 to 1 if only the work zone duration cost of permanent equipment is included. I-44 had a benefit-cost ratio of 17 to 1 if all of the cost of permanent equipment is included and 48.6 to 1 if only the work zone duration cost of permanent equipment is included. The benefits for each of these case studies could be better estimated if there was data for a period of time when DMS was not used, since accident rate reduction could be added to the I-70 benefits and delay reduction could be added to the I-44 benefits.

This document provides quantitative benefits of using Intelligent Transportation Systems (ITS) in highway construction and maintenance work zones. The summary report covers case study sites in the District of Columbia, Texas, Michigan, Arkansas, and North Carolina and provides insights into the mobility and safety benefits of ITS for work zone traffic management.

Intelligent Transportation Systems, or ITS, is the application of electronics, communications, and/or information processing to improve the efficiency and/or safety of surface transportation systems. ITS can improve transportation safety, mobility, and societal productivity through the integration of advanced communications technologies into the transportation infrastructure and in vehicles. ITS encompasses a broad range of wireless and wire line communications-based information and electronics technologies. This report documents several case studies of how agencies used work zone intelligent transportation systems (ITS) to mitigate safety and mobility issues in work zones. The report illustrates how to apply a systems engineering-based decision-making process to designing, selecting, and implementing a system to address work zone needs. The report presents the steps followed by the agency/contractor in this decision-making framework for five specific projects. The work zone ITS deployments documented provide examples of selecting and deploying commercial off-the-shelf (COTS) systems; a tailored design and integration of ITS for a specific work zone purpose; and using and supplementing permanent ITS deployments for work zone management purposes. Tips are provided for how to effectively apply ITS to other work zones.

This volume, the first to result from the Diebold Institute Information-Based Infrastructure Project, explores the links between business and government in the development of intelligent transportation systems (ITS) technology. The work focuses on road and vehicular infrastructures, comparing those of the U.S., Europe, and Japan, and the roles that ITS can play in solving major current and anticipated future transportational problems. Special attention is given to environmental and economic concerns. The world's infrastructure requires refurbishing, but it especially requires rethinking. The computer has transformed business enterprises and now information technology can change our environment. This book explores the benefits and how to achieve them through the use of intelligent transportation systems (ITS). The implementation of ITS will potentially lead to individual drivers, fleet operators, and public transit users saving vast amounts of journey time and fuel, to a significant reduction in pollution and to improved road safety. The Japanese are ahead of the U.S. and Europe in the area of intelligent transportation systems, using position location devices, and electronic maps. Most look at this development as one that helps speed passenger cars, but this book details the economics which point to the technology being equally good for speeding trucks and easing the movement of freight. Traffic avoidance is only part of the problem although route guidance is helpful. Financing of projects in ITS is an important area for innovation and ITS could be a source of revenue to municipalities rather than an expense.

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.

The Intelligent Transportation System (ITS) Program is a cooperative effort by government, private industry, and academia to apply advanced technology to the task of resolving the problems of surface transportation. The objective is to improve travel efficiency and mobility, enhance safety, conserve energy, provide economic benefits, and protect the environment. The current demand for mobility has exceeded the available capacity of the roadway system. Because the highway system cannot be expanded, except in minor ways, the available capacity must be used more efficiently to handle the increased demand. ITS applies advanced information processing, communication, sensing, and computer control technologies to the problems of surface transportation. Considerable research and development efforts will be required to produce these new technologies and to convert technologies developed in the defense and space programs to solve surface transportation problems. ITS has been subdivided into six interlocking technology areas. This book addresses human factors concerns for four of these areas: * Advanced Traveler Information Systems are a variety of systems that provide real time, in-vehicle information to drivers regarding navigation and route guidance, motorist services, roadway signing, and hazard warnings. * Advanced Vehicle Control Systems refer to systems that aid drivers in controlling their vehicle particularly in emergency situations and ultimately taking over some or all of the driving tasks. * Commercial Vehicle Operations address the application of ITS technologies to the special needs of commercial roadway vehicles including automated vehicle identification, location, weigh-in-motion, clearance sensing, and record keeping. * Advanced Traffic Management Systems monitor, control and manage traffic on streets and highways to reduce congestion using vehicle route diversion, automated signal timing, changeable message signs, and priority control systems. Two technical areas are not specifically addressed in individual chapters, but many aspects of them are covered in associated chapters: * Advanced Rural Transportation Systems include systems that apply ITS technologies to the special needs of rural systems and include emergency notification and response, vehicle location, and traveler information. * Advanced Public Transportation Systems enhance the effectiveness, attractiveness and economics of public transportation and include fleet management, automated fare collection, and real-time information systems.
