Available ITS Benefits and Unit Costs
Database Related Documents
The desk reference is intended to be a source of information for quickly finding examples of ITS benefits. It is often difficult to compare data from one project to another. This is due to the fact that there are several different variables involved between different implementations of ITS user services. Thus, statistical analysis of the data is not done. Some of the examples in the desk reference therefore show ranges of reported impacts. Others show only a single example from a record in the database.
Data is presented in two forms: 1) Program Area or Taxonomy, and 2) by the few good measures. The PDF file contains two pages, one for each presentation of the data.
The one page Intelligent Vehicles desk reference provides example findings from the Benefits Database documenting the impacts of intelligent vehicle ITS applications. In addition to the findings highlighted in the larger Benefits Desk Reference, this document provides additional examples for each of three major areas of intelligent vehicle application: Collision Warning Systems, Driver Assistance Systems, and Collision Notification Systems.
The Taxonomy is the classification scheme used to categorize reports within the ITS Benefits Database. The figure contained in the PDF file depicts the categories used within the "View by Component" section of the Benefits Database.
For the first time, the U.S. Department of Transportation (DOT) is presenting in one document benefits and costs information for Intelligent Transportation Systems (ITS) implementations. Intelligent Transportation Systems Benefits and Costs: 2003 Update represents a culmination of DOT’s active 10-year data collection on the impact of ITS projects on surface transportation and the cost of implementing them. This compendium builds on previous ITS benefits reports, and refers readers to the online database as well as cited references for additional details on the examples cited.
The HTML version of this report provides links to relevant information within the ITS Benefits and Unit Costs database. Look for the “Benefits” links, and links to the Unit Costs subsystems in each section of the report.
Free printed copies of the report are also available, by e-mailing itspubs@fhwa.dot.gov.
Periodically, the ITS Joint Program Office publishes a report as a compendium of reported impacts of ITS that have been collected from a number of sources. The purpose of the report is to provide the JPO with a tool to transmit existing knowledge of ITS benefits to federal, state, and local decision makers and to the interested public. This report is also intended to provide the research community with information about where further analysis is required in the ITS program. The 2001 Update provides a comprehensive discussion of the reported impacts of ITS contained in the online database, with brief summaries of the documents entered since the 1999 Update report.
The 2001 Update report was made available electronically in April 2001 throught JPO's Electronic Document Library. Click the link above to download the PDF file. Due to the size of the electronic file, the PDF version must be downloaded in several segments. These files corresponded to several of the chapters linked in the table of contents within the report. Printed copies are also available.
The ITS Benefits: 1999 Update report provides a comprehensive discussion of the reported impacts of ITS based on documents entered in the online database before early 1999. Summary discussions of many of these documents are included in the report. The report was made available to the public in May 1999. An electronic version is available throught the link above, and printed copies are also available.
This is the third in a series of reports documenting the results of a periodic assessment of the state of knowledge regarding the impacts of various ITS implementations on the surface transportation system. The report presents the results of a web-based survey distributed to ITS stakeholders across the United States. The 2003 survey asked participants to rate the importance of continued evaluation of implementations in each of the ITS application areas.
This is the second in a series of reports documenting the results of a periodic assessment of the state of knowledge regarding the impacts of various ITS implementations on the surface transportation system. The report presents the results of the 20 March 2001 workshop in Washington, DC sponsored by the Benefits, Evaluation and Costs (BEC) committee of ITS America and a corresponding survey distributed to ITS stakeholders across the United States. In contrast to the survey distributed in 2000, the 2001 survey asked participants to rate the importance of continued evaluation of implementations in each of the ITS application areas. In the survey distributed in 2000, participants were only questioned about the need for research in the areas with minimal coverage in the online ITS benefits database. The 2001 survey also requested ratings for applications of ITS for commercial vehicle operations (ITS/CVO) and intermodal freight.
The purpose of this report is to summarize and highlight where gaps or limited knowledge exists concerning the benefits of ITS services. It concentrates on the areas of metropolitan and rural ITS user services, and is intended to point out where additional evaluation of those services may be needed. The gaps highlighted are used to show where little data have been collected in a particular measure or ITS service. The lack of benefits data in an ITS service area does not mean that the service is not a good one. Rather it indicates where more evaluation may be needed to understand the full impacts of the service. In many cases, ITS services contain broad societal benefits or other intangible effects that may not be measurable. The results of this report are intended to assist the U.S. DOT's ITS Joint Program Office and provide some guidance to researchers for establishing which gaps are considered to be the most important and determining where limited evaluation resources may provide the most advantage.
The information presented in this report was developed as a result of a workshop sponsored by the Benefits Evaluation and Cost (BEC) committee of ITS America. The workshop was held on 12 July, 2000 and involved members of a data needs task force. The purpose of the task force was to develop, review and rate the listing of data needs. The rating of the data needs lists was accomplished in the form of a survey sent to the 31 members of the task force, of which 23 attended the workshop, and 18 returned the survey. Survey participants where asked to rate the items in the data needs list based on their assessment of the importance of conducting further evaluation in that ITS area. The rating occurred on a scale of 0 to 5 with 0 being no importance, and five being high importance.
The one page handout is intended to "advertise" the database. It has been widely distributed at conferences, in email, on company bulletin boards, etc. The handout includes the purpose of the database, web site addresses, etc.
This document is a useful guide for those considering submitting data for inclusion in the database. The criteria document describes the procedure used in considering documents for inclusion in the ITS benefits database. It generally outlines the criteria that must be met by a document and describes the consideration given to documents from various sources (such as journal articles, conference presentations, and trade journal articles).
This working paper has been prepared to provide new estimates of the costs to deploy Intelligent Transportation System (ITS) infrastructure elements in the largest metropolitan areas in the United States. It builds upon estimates that were distributed in June 1995 by the Federal Highway Administration (FHWA).* Since 1995, new sources of ITS cost estimates have appeared. Hence, it is now useful to determine whether the national deployment cost estimate has changed appreciably. The working paper reflects the cost estimates to deploy ITS infrastructure based on 2000 deployment values.Updates to this working paper coincide with the results from tracking the deployment of ITS in the United States. To date deployment tracking data are available for 1997, 1999, and 2000. The original working paper (dated September 1999) was written to update the 1995 cost estimate using the 1997 deployment tracking results. Since that time, deployment tracking results from 1999 have become available and incorporated into the first revision of this working paper (dated August 2000). The first update was in the form of an addendum to the original document. With the 2000 deployment tracking data now available, it is time to update the national deployment cost estimate. This second revision of the working paper will be again in the form of an addendum and can be found at the end of the original report.

*Office of Traffic Management and Intelligent Transportation Systems (HTV-10), Cost Estimate and Assumptions for the Core Infrastructure, FHWA, June 1995. The ITS Infrastructure was called the Core Infrastructure in 1995.
The purpose of this working paper is to provide an estimate of the federal proportion of funds expended on ITS infrastructure deployments for fiscal year (FY) 2000 using budget and planning data from state departments of transportation (DOTs). Expenditures associated with ITS infrastructure deployments include: capital, operations, management, and maintenance. The intent is to update this working paper as additional state DOT ITS budget and planning data become available.
The primary objective of this working paper is to estimate the federal proportion of expenditures for ITS infrastructure deployments in FY 2000 as a range (using actual state DOT budget and planning data). A secondary objective is to provide insight into how states fund ongoing operations and maintenance costs for their ITS deployments.
The workshop, The Truth About the Costs of ITS: Implications for Improving Planning and Operations in Traffic Management, was held in conjunction with the TRB 81st Annual Meeting, on Sunday, January 13, 2002, at the Washington Hilton, Washington, DC. The proceedings of the workshop contain: the workshop agenda; the questions posed and responses given during the planning and operations panel sessions; summary of the facilitated discussions and closing remarks; and workshop presentations, all of which are available from the ITS America website.
