This book was released on 2015 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: Purpose of Report - This report responds to a Congressional request for an assessment of the 5.9 Gigahertz (GHz) Dedicated Short Range Communications (DSRC) in accordance with the requirements provided by Congress in the Moving Ahead for Progress in the 21st Century Act ("MAP-21"; P.L. 112-141), Section 53006, codified at 23 U.S.C. 518. The report: provides an assessment of the status of DSRC technology and applications, including known and potential gaps; describes a recommended implementation path; and discusses opportunities to use commercially available communications for Connected Vehicle applications under specific circumstances. The assessment is predominantly derived from U.S Department of Transportation research, analysis, and deployment planning that has been performed in partnership with stakeholders and industry experts over the last decade. The assessment is validated by an independent evaluation provided by the National Research Council (NRC) of the National Academies of Sciences, Engineering, and Medicine, who engaged with third party experts in reaching their conclusions. The NRC Letter Report was delivered to Congress in April 2015 and is included in this report as Appendix J. This report has been revised as needed to respond to each comment in the NRC Letter Report. Significance of DSRC DSRC is a Wi-Fi derivative technology developed to meet specialized needs for secure, low latency, wireless mobile data communications. It is uniquely configured to enable continuous, high-speed, trusted and authenticable data exchange among moving vehicles and between vehicles and roadway infrastructure or mobile devices, to support safety-critical applications, as well as less demanding mobility and environmental applications. DSRC has proven the ability to provide all of the critical attributes needed to support Connected Vehicle safety applications, which no other wireless technology has at this time. DSRC is important to the Nation as it can be configured to enable real-time crash-avoidance alerts and warnings- offering a significant opportunity to achieve a transformation in transportation safety, with the potential to address 83 percent of light-vehicle crashes involving unimpaired drivers. DSRC also provides an important new capability for enhancing the performance and safety of automated vehicles- allowing automation to reach its full potential. However, to support an implementer's ability to leverage a wide range of communications options that are in use today, USDOT is also advancing state-of-the-industry practices in security credential management and message protocols, data distribution and capture methodologies, and data warehousing. These actions address the Congressional intent to ensure competition by not showing preference in the use of any particular frequency for non-safety related V2I operations. Known and Potential Gaps USDOT finds that there are no significant gaps in DSRC technologies or applications. Recent, emerging issues that have created some uncertainty include requests for coexistence with widespread use of Unlicensed-National Information Infrastructure (U-NII) devices, and a desire for spectrum management that can provide an active response to problems as they arise. A critical assumption in the development of DSRC-based technologies and applications was that spectrum sharing of this nature was not intended. To ensure that proposed changes in the 5.9 GHz DSRC band will not jeopardize safety critical crash avoidance capabilities, USDOT is working with industry partners and in cooperation with the Federal Communications Commission (FCC) and the National Telecommunications and Information Administration (NTIA) to define and assess the potential for harmful interference from unlicensed broadband devices in the DSRC band. It will be important to allow sufficient time to rigorously test potential sharing solutions-including field testing under real-world conditions. Implementation Path - Working with stakeholders, USDOT has synthesized expectations and preliminary plans into a candidate roadmap to guide industry and public agency implementation efforts. It offers three key milestones for the year 2040: 1. 90 percent of the US light duty vehicle fleet is DSRC enabled; 2. 80 percent of all traffic signals are DSRC equipped; and 3. DSRC exists at up to 25,000 additional safety-critical roadway locations. The roadmap is predicated primarily on a market-driven scenario wherein applications are provided by industry for consumer adoption and public agency implementation. It assumes an austere near-term budgetary environment for both public and private sectors, and builds upon DSRC footholds established through test and operational environments already existing in seven states, and others anticipated to be developed in conjunction with upcoming regional pilot deployments. As DSRC-based technologies and Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) applications are advancing in a similar manner in Europe, Japan, South Korea, Australia, and Canada, USDOT is working to harmonize operational policies and voluntary industry standards to achieve global compatibility and to facilitate domestic access to international markets. Although the National ITS Architecture and ITS Standards accommodate both DSRC and other wireless and wireline communication technologies, a Connected Vehicle Reference Implementation Architecture (CVRIA) has been prepared, recognizing the complex nature of cooperative systems. The CVRIA illustrates one or more approaches to implementing Connected Vehicle applications, offers choices for using different technologies, and highlights the use of essential technical standards. Conclusion - USDOT's assessment is that DSRC is ready for deployment and that DSRC-based technologies and applications offer a path to a safer and more efficient surface transportation system for America. This assessment is offered in support of the upcoming National Highway Traffic Safety Administration (NHTSA) V2V Notice of Proposed Rulemaking (NPRM) and the Federal Highway Administration (FHWA) V2I Guidance to Implementers."--Technical report documentation page.

This book was released on 1998-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.
Download or read book Where the Weather Meets the Road written by National Research Council and published by National Academies Press. This book was released on 2004-03-31 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weather has broad and significant effects on the roadway environment. Snow, rain, fog, ice, freezing rain, and other weather conditions can impair the ability of drivers to operate their vehicles safely, significantly reduce roadway capacity, and dramatically increase travel times. Multiple roadway activities, from roadway maintenance and construction to shipping, transit, and police operations, are directly affected by inclement weather. Some road weather information is available to users currently, however a disconnect remains between current research and operations, and additional research could yield important safety and economic improvements for roadway users. Meteorology, roadway technology, and vehicle systems have evolved to the point where users could be provided with better road weather information through modern information technologies. The combination of these technologies has the potential to significantly increase the efficiency of roadway operations, road capacity, and road safety. Where the Weather Meets the Road provides a roadmap for moving these concepts to reality.
Download or read book Economic Impacts of Intelligent Transportation Systems written by E Bekiaris and published by Elsevier. This book was released on 2004-07-24 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are unique complexities associated with the economic valuation of Intelligent Transportation Systems (ITS) and telematics. Traditional methods of quantitative analysis may not be appropriate in accurately and reliably assessing the economic impacts of these technologies. Although advanced transportation and related technologies are being planned and deployed at an increasingly rapid pace, many of the technologies are still relatively new, and their use may not be widespread. Much of the initial information and statistics gathered have been anecdotal and have focused more on benefits rather than costs. Therefore, difficulties arise due to the lack of historical data and 'lessons learned' from which to draw upon. In addition, compared with traditional transportation infrastructure, ITS technologies have different life cycles, cost structures, and a number of interrelated elements. This book addresses these concerns and proposes new economic assessment techniques as well as modifications to existing ones. Included are case studies from a multitude of North American, European, and Asian nations and major metropolitan areas covering a wide range of ITS technologies including freeway management, electronic toll collection, advanced driver assistance systems, and traveller information systems.
