      <title>VISUAL CONFIRMATION OF VOICE TAKEOFF CLEARANCE (VICON) OPERATIONAL EVALUATION. VOLUME II. OPERATIONS AND MAINTENANCE MANUAL</title>
      <link>https://trid.trb.org/View/169086</link>
      <description><![CDATA[This document is Volume II of the Visual Confirmation of Voice Takeoff Clearance (VICON) Operational Evaluation. It contains working drawings and schematic diagrams, technical details, and maintenance and detailed operational procedures for the VICON system that was installed at Bradley International Airport, Windsor Locks, Connecticut. The drawings, instructions, and charts in this volume are reproduced exactly as they were used by the Bradley maintenance and air traffic control specialists; no effort was made to formalize or improve the appearance of this information. This volume, therefore, would be utilized if one is interested in considering future implementation or design modification of the VICON system. Seven appendices were added in order to consolidate under one cover the various operational, maintenance, and design details for the VICON system and its components.]]></description>

      <title>DIGITIZED RADAR DATA COMPRESSOR</title>
      <link>https://trid.trb.org/View/75610</link>
      <description><![CDATA[The data compressor (DACOMP) is a special-purpose device designed specifically to increase radar data recording capabilities at air route traffic control centers (ATRCC's). The DACOMP accomplishes this by compressing the number of channels each radar occupies prior to recording, thereby reducing the number of tape tracks required for each radar. The three 2400 bit-per-second channels of a digitized radar are compressed onto one high-speed (9375 bit-per-second) channel. Because of the threefold reduction in recording track requirements, use of DACOMP's will enable ARTCC's to record information from an increased number of radar sites on the recorders that are available to them. This report explains the installation, use, theory of operation, and maintenance of the DACOMP. (Author)]]></description>

      <title>APPLICABILITY &amp; UNIQUENESS OF A SCHEMATIC VERSION OF AN OPERATING &amp; MAINTENANCE PLAN FOR THE LOS ANGELES METRO RED LINE</title>
      <link>https://trid.trb.org/View/477311</link>
      <description><![CDATA[In order to meet the Systemwide Design Criteria for the Los Angeles Metro Red Line, an Operations and Maintenance Requirements Plan was developed.  The focus of this presentation is to show how some key issues were discussed and decisions were made using the system operations and maintenance requirements plan as a key tool.  Examples of these issues are the requirement for optimum placement of crossovers in order to meet single tracking headway needs, peak operating headways based on projected ridership corridors for each branch line and the trunk section, crossover type and parameters taking into account passenger comfort.]]></description>

      <title>EVOLUTION PROGRAM FOR DESIGN OF RECTILINEAR BRANCHED NETWORKS</title>
      <link>https://trid.trb.org/View/425975</link>
      <description><![CDATA[The authors present a new algorithm for designing the layout of rectilinear branched pipeline networks.  A binary solution-coding scheme, similar to the type commonly used in genetic algorithms, is employed; however, two new operators, recombination and perturbation replace the genetic algorithm operators of crossover and mutation.  An architecture based on evolution strategy is used to exploit the unique characteristics of the new operators. The technique is illustrated on a small problem and compared with a method based on heuristics.  Through demonstration and comparison, investigators conclude that the evolution program is capable of generating better solutions than the heuristic method.]]></description>

      <title>SCHEMATIC VIEWS OF NETWORKS - WHY NOT HAVE IT ALL?</title>
      <link>https://trid.trb.org/View/382852</link>
      <description><![CDATA[Network applications, such as routing analysis and dispatching require graphic representation of potentially complicated network maps to the user. The ability of the user to quickly and accurately pick out relationships among links and nodes, and to visually trace paths through the network, can be hampered by "spaghetti-like" networks. One method for simplifying and clarifying the visual displays of networks in a computerized environment, such as in network analysis and control software, is to create a schematic version of the network. To provide a schematic view at the expense of losing the accuracy of the detailed version, however, is a high price to pay. This paper introduces the concept of schematic maps, their benefits to GIS applications, the current state of affairs, and suggestions for future improvements.]]></description>

      <title>OPTIMAL LONG-TERM SCHEDULING OF BRIDGE-DECK REPLACEMENT AND REHABILITATION</title>
      <link>https://trid.trb.org/View/365108</link>
      <description><![CDATA[The paper presents a (0-1) binary decision model to determine optimal long-term deck replacement or rehabilitation schedules for a system of independent bridges.  The model is applicable to multiple decks and is driven by over-all long-term cost considerations. Maintenane activites are scheduled based on the current condition and future deterioration of each deck.  An example is presnted using 3 bridges in North Carolina and a piecewise linear deterioration function.  Possible extensions using nonlinear deterioration functions and additional rehabilitation alternatives are discussed.  The study results show that the model can be used by engineers as an aid in the long-term scheduling of bridge maintenance activities.]]></description>

      <title>GEOTEXTILES. PART 4. DETERMINATION OF THE PUNCTURE RESISTANCE (CBR PUNCTURE TEST)</title>
      <link>https://trid.trb.org/View/359258</link>
      <description><![CDATA[This Part of BS 6906 has been prepared under the direction of the Textiles and Clothing Standards Policy Committee and forms Part 4 of a British Standard on methods of test for geotextiles.  This Part of BS 6906 describes procedures based on the California bearing ratio (CBR) puncture test which was developed to simulate the stresses imposed on geotextiles laid on soft subgrade during the spreading and compaction of coarse granular material.  The test is applicable to most types of geotextiles including separation type materials, woven fabrics, knitted fabrics and nonwoven material, but not to high strength reinforcement fabrics, geogrids or geotextiles with apertures greater than 10 mm. For Parts 1 and 3 see IRRD nos 809942, 808510. (TRRL)]]></description>

      <title>NAASRA/ARRB WORKSHOP ON THE USE OF RELATIVE COMPACTION IN THE CONTROL OF ROADWORKS; PROCEEDINGS, INCLUDING DISCUSSION FROM THE WORKSHOP ON MEASUREMENT AND USE OF RELATIVE COMPACTION HELD DURING THE 11TH ARRB CONFERENCE</title>
      <link>https://trid.trb.org/View/191361</link>
      <description><![CDATA[The purpose of the workshop was to provide a forum for engineers from state road authorities to discuss the methods of establishing compaction standards for soils, aggregates and asphaltic concrete in the laboratory and the field as well as the various methods of measuring the density of these materials and thus the relative compaction achieved. Effects of materials and methods of measurement of density on the variability of the results obtained, and the methods of specification and acceptance were also discussed. Adequacy of existing standards and procedures was examined and studies for the improvement of practices proposed.  The workshop was held at the Australian Road Research Centre, Vermont South, Victoria on 1st and 2nd April, 1982 with the second workshop being held at the 11th ARRB Conference on 24th August 1982.  The ISBN of the microfiche version is 0 86910 083 1.  For the abstracts of individual papers see TRIS nos. 378032-046.  The conference preprints were issued under the title: NAASRA/ARRB Workshop on Measurement and and Use of Relative Compaction of Soils, Aggregates and Asphaltic Concrete in Road Construction, see 1982 ARI No. 302003.

      <title>AN AUTOMATIC VEHICLE CLASSIFICATION SYSTEM</title>
      <link>https://trid.trb.org/View/170729</link>
      <description><![CDATA[This manuscript documents the development of an automatic surface transportation identification system to break down vehicle noise sources, by class, into categories of truck, bus, car, and motorcycle. Such a classification would enable the Army, U.S. Environmental Protection Agency and communities to see what contribution each category of vehicles makes to the overall noise at a monitored site. The system designed for this function was based on a configuration of photoelectric emitters and receivers set up along the road at a monitoring site. This system uses hardware-implemented logic and performs a series of algorithms on the outputs from the sensors created when a vehicle interrupts the beams as it passes through the system. The unit was tested in a scaled model system; test results indicate that the system is feasible for full scale use. In addition, various portions of the system design can be used by other vehicle study projects, e.g. for projects concerned with vehicle speed or for traffic study projects that require an axle counter or vehicle height indicator.

      <title>MANUAL OF SOIL LABORATORY TESTING. VOLUME 2: PERMEABILITY, SHEAR STRENGTH AND COMPRESSIBILITY TESTS</title>
      <link>https://trid.trb.org/View/176898</link>
      <description><![CDATA[This volume covers standard laboratory tests for the measurement of soil permeability, CBR value, shear strength, and consolidation characteristics.  References are made to British standards and to U.S. (ASTM) standards where relevant.  Otherwise test procedures follow accepted practice in Britain, including a number of test methods or modifications which have gained acceptance in recent years. Shear strength tests cover direct shear tests on sands and clays in the shearbox, including quick, drained, and residual strength tests; and measurement of the quick undrained strength of cohesive soils with the laboratory vane, unconfined compression and triaxial compression apparatus.  Tests on large samples are outlined.  (TRRL)]]></description>
