      <title>Washington State Ferries Wireless Connection High-Speed Data Project</title>
      <link>https://trid.trb.org/View/896076</link>
      <description><![CDATA[The Washington State Ferries (WSF) High Speed Data Project is a Research & Development project to study the feasibility of providing technologies capable of very high data transmission rates for wireless networks in a mobile marine environment. WSF is installing a high speed network infrastructure onboard vessel in an effort to improve ferry security and system monitoring. WSF wishes to explore ways of increasing transmission rates, facilitate a larger number of real-time camera views and improve overall performance. Intellicheck Mobilisa has established the viability of that system. The initial project test location selection resulted in using the Fauntleroy/Vashon Island/Southworth Ferry route. A demonstration of promising technologies was performed in June 2007 at the Fauntleroy terminal, utilizing the MV Klahowya. Technological concepts resulted in the decision being made to perform the final evaluation at the same terminal utilizing the same ferry. During final evaluation testing, several issues developed, including interference from a WSF WI-FI installation, power issues on the MV Klahowya, and power issues at the terminal resulting from a generator installation. The decision was made to move the final evaluation to the Port Townsend/Keystone ferry route, where it was successfully conducted in March 2008.]]></description>

      <title>Independent Verification and Validation of Washington State Ferries' Wireless High Speed Data Project</title>
      <link>https://trid.trb.org/View/869725</link>
      <description><![CDATA[The following Independent Verification and Validation (IV&V) report documents and presents the results of a study of the Washington State Ferries Prototype Wireless High Speed Data Network. The purpose of the study was to evaluate and determine if real-time security monitoring applications could be consistently available from shore during the vessels’ normal daily operations as well as in emergency situations. The Washington State Ferries Prototype Wireless High Speed Data network project aims to demonstrate new technologies that may provide real-time surveillance capabilities and records for law enforcement agencies in the event of an emergency. Research methodologies included full-scale monitoring tests in combination with data collection phases over multiple weeks. These results were applied to track and evaluate high-speed wireless connections from the ferries to shore. It is the specific intent of this study to determine if the prototype network provides reliable connectivity, and protection against radio eavesdropping, network-based viruses, worms, and traffic floods. The findings of the study were a result of multiple weeks of data collection from communication equipment placed on board the Washington State Ferry vessels. The intended audience of this report is government agencies wishing to implement secure high-speed mobile wireless data networks. The technical nature of the findings and recommendations in this report are intended to help technical teams make decisions regarding technology and implementation choices when building new wireless networks.]]></description>

      <title>Chip Seal Design Using High Speed Data</title>
      <link>https://trid.trb.org/View/795889</link>
      <description><![CDATA[The purpose of this paper is to suggest data that can be used for chip seal design purposes. It reviews analysis of laser measured and sand circle measured texture levels and the relative effect of changes in texture on the calculated residual binder application rate used for chip seal application. This procedure has been successfully used on Transit New Zealand’s Coastal Otago Hybrid Maintenance Contract chip seal program for the past two years to check traditional sand circle texture measurements. Amongst other surface characteristics, the levels of macro-texture on New Zealand State Highways are measured and assessed by a laser device that measures surface texture in both wheel paths and between wheel paths. It finds the relative precision of the laser measurements is adequate for chip seal design purposes. The difference between the two assessment methods is negligible in its effect on the resultant calculation of binder application rates.]]></description>

      <title>A Concerted Effort</title>
      <link>https://trid.trb.org/View/792905</link>
      <description><![CDATA[Despite significant advances in earthquake engineering in the past 40 years, the response of the built environment to earthquakes is still not fully understood.  This article describes how the National Science Foundation is helping to bridge this knowledge gap by providing funds for 15 U.S. universities to expand and upgrade their earthquake simulation research facilities.  These facilities are now connected by a high-speed network that allows data sharing, remote observation and remote control of earthquake experiments.  Researchers hope that this network will foster an environment that will lead to more sophisticated earthquake simulations, accelerate progress in earthquake engineering research and ultimately lead to better seismic designs.]]></description>

      <title>A New Ground-to-Train Communication System using Free-Space Optics Technology</title>
      <link>https://trid.trb.org/View/792579</link>
      <description><![CDATA[This paper proposes a new ground-to-train communication system that uses free-space optics between a train and the ground.  In the proposed system, a cylindrical concave lens spreads the incoming beam from the transmitter Laser Diode (LD) horizontally to form a wide fan-shaped beam.  The fan-shaped beam is projected to a train and the width of the projected beam is equal to the length of a typical bullet-train car.  This transmitter with cylindrical concave lens and a receiver Avalanche Photo Diode (APD) are installed on a train and the ground, and the horizontally spread beam is received continuously by the corresponding receiver.  The train can keep a communication link continuously to the ground thanks to this spread beam.  The paper analyzed the performance of the proposed system by experiments.  The experimental results show that a sufficient received Signal-to- Noise Ratio (SNR) can be obtained when a train is not moving; therefore, the signal can be received continuously even when the train is moving.  Furthermore, in order to keep a continuous communication link even when the train vibrates or shifts vertically, the vertical spread angle of a laser beam is adjusted between 0.1 degrees and 0.5 degrees. These experimental results lead to the conclusion that this system is expected to be a Giga-bit class high speed communication technology between the train and the ground.]]></description>

      <title>SWIFT: SEATTLE WIDE-AREA INFORMATION FOR TRAVELERS, EVALUATION SUMMARY</title>
      <link>https://trid.trb.org/View/497114</link>
      <description><![CDATA[The SWIFT (Seattle Wide-area Information For Travelers) project was a field operational test of a wide-area Intelligent Transportation System (ITS) communications system using a flexible FM sub-carrier High Speed Data System (HSDS).  The test was conducted in a public/private partnership with the Washington State Department of Transportation, King County Metro Transit, Delco Electronics, Etak Inc., IBM, Seiko Communications Systems, Metro Traffic Control and the Federal Highway Administration. Three devices were used, by the public, to receive the traveler information:  a Delco car radio (capable of providing vector navigation in addition to personal paging and the SWIFT messages); a Seiko wrist watch pager; and a portable computer (capable of providing graphic displays of traffic advisories and bus positions).  After the 15-month test, interviews with the 600 Seattle commuters/participants were conducted to assess user acceptance.  A communications study evaluated the adequacy of the HSDS system to disseminate traveler information.  An architecture study assessed the effectiveness of the various components to carry out SWIFT operations.  An institutional issues study documented the history of the project and assessed the institutional issues confronted.  A deployment cost study investigated the cost of deployment of a SWIFT system and assessment of potential profitability.  The first five reports in this series detail individual aspects of the project.]]></description>
