      <title>Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS)</title>
      <link>https://trid.trb.org/View/2209148</link>
      <description><![CDATA[A set of engineering standards has been completed for the design and maintenance of marine oil terminals. These "Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS) became regulatory in February 2006. The Standards were developed by the Marine Facilities Division of the California State Lands Commission and include criteria for above and under water inspection, structural (and seismic) rehabilitation, as well as new design, fire, piping, mechanical and electrical systems. These standards address both new terminals or new components as well as existing facilities.]]></description>

      <title>Seismic Retrofit of an Existing MOT Using Float-In Construction for Rapid Turnaround</title>
      <link>https://trid.trb.org/View/1650844</link>
      <description><![CDATA[The Chevron Eureka Terminal provides a critical economic lifeline to northern California as it is the only active marine-based petroleum terminal serving the Greater Eureka area (approximately 260 miles north of the San Francisco Bay Area). During the MOTEMS initial audit, the existing facility was found seismically deficient and required seismic retrofit. Moffatt & Nichol and geotechnical consultant EMI developed a float-in construction replacement platform design that minimized facility downtime, satisfied the regulatory requirements, and reduced risk of loss to the facility. This paper discusses the criteria and analytical methods used, the design and construction approach and their impact on material selection and operational impact, and presents lessons learned from the completed construction.]]></description>

      <title>Seismic Design Standards for Nonstructural Components and Nonbuilding Structures in Motems</title>
      <link>https://trid.trb.org/View/1650839</link>
      <description><![CDATA[This paper describes development of seismic design standards for nonstructural components and nonbuilding structures in California State Lands Commission (CSLC), Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS). For this purpose, a simple procedure is developed based on ASCE 7 standard and is simplified to structural configuration appropriate to those typically found in marine oil terminals. Underlying assumptions in the MOTEMS procedures and range of applicability are identified. It is shown that the MOTEMS procedure, in general, provides conservative estimate of forces, when compared with results from response history analysis, in nonstructural components and nonbuilding systems supported on marine oil terminals.]]></description>

      <title>Economic Analysis of Crack Treatment Methods Using HDM-III Modeling</title>
      <link>https://trid.trb.org/View/1658766</link>
      <description><![CDATA[Crack sealing treatment includes the use of a router to create a reservoir on the intended cracks, whereas crack filling is given without any modification to the crack wall. With sealing treatment the pavement can have longer service period because of its good adhesion and cohesion performance. However, the initial cost of sealing is higher due to the use of extra material, equipment and labor. As a result, the aim of this study is to investigate the long-term cost-effectiveness in between these two treatment techniques in Texas and to observe if the longer service period can compensate the higher initial cost of sealing treatment. For this purpose, the initial cost inputs have been identified and a highway design and maintenance standard model (HDM-III) used to evaluate the most cost-effective pavement maintenance between crack sealing and filling treatment over a 25-year analysis period. Agency, capital and net present value have been calculated by using HDM-III based upon average daily traffic (ADT),  altitude and road length. The results of this study indicated that (1) crack sealing is more cost-effective pavement maintenance compared to crack filling over a long period of time; (2) agency cost can be reduced by 15% and 14% based on ADT and road length analysis, respectively, by implementing crack sealing treatment; (3) capital cost in terms of ADT and road length with crack sealing maintenance can be saved by 24% and 19%, respectively; (4) the net present value with crack sealing treatment after a 25-year analysis period is higher for ADT and road length compared to crack filling by 18% and 19%, respectively; (5) the cost-effective resealing interval years of 5 years is proposed when the unit cost of routing increased by 25%.]]></description>

      <title>ECONOMIC AND FINANCIAL FEASIBILITY OF TRUCK TOLL LANES</title>
      <link>https://trid.trb.org/View/682015</link>
      <description><![CDATA[The economic and financial feasibility of heavy-truck toll lanes was analyzed.  This research expanded the line of inquiry of previous researchers by analyzing toll lanes for exclusive use by heavy trucks (i.e., large size and capacity).  Implementation of such a toll system was studied relative to productivity changes, toll-lane fees, users travel time and vehicle operating cost savings, and impact on infrastructure costs.  The economic benefits were estimated using the Highway Design and Maintenance Standards Model developed by the World Bank.  The analyses, complemented with sensitivity analyses of key variables, indicate that heavy-truck lanes are economically and financially viable.]]></description>

      <title>STATUS OF SHRP WORK ZONE SAFETY DEVICES</title>
      <link>https://trid.trb.org/View/487965</link>
      <description><![CDATA[The objectives of this presentation is to report on progress of implementing SHRP work zone safety products.  The following topics will be covered:  (1) current status of maintenance safety devices; and (2) future implementation activities. The most unique item about the Strategic Highway Research Program (SHRP) has been the united effort to identify study objectives and share guidance of the research.  The hundreds of people involved in serving on the guiding committees, coupled with the many loan staffers, share in the ownership of the new developments.  This will help expedite implementation because, human nature says it is always easier to accept your own ideas, as compared to those from others.  The Federal Highway Administration (FHWA) was chosen to have the lead for implementation and management of the $108 million from the Intermodal Surface Transportation Efficiency Act for SHRP implementation and continuation of the Long Term Pavement Performance (LTPP) studies.  Instead of Advisory Committee as used during the life of SHRP, a new name has been selected for a similar operation in relation to guiding implementation.  The name is Technical Working Groups (TWG).  Under the TWD's, Expert task Groups will be organized as needed.  It is believed that the FHWA recognizes that SHRP was initiated by the states, for the greater part was directed or guided by the states, and implementation is no different.  The states have the key involvement and responsibility for this activity, too.  The Technical Working Groups are organized to provide the needed coordination, with this thought in mind.  The SHRP catalog seems to be the biggest catalyst that has helped states become active in looking for products for potential use in their individual operations.]]></description>

      <title>SWITCH POINT/STOCK RAIL WEAR, MEASUREMENT AND MAINTENANCE STANDARDS</title>
      <link>https://trid.trb.org/View/485772</link>
      <description><![CDATA[Turnout and switch maintenance are major concerns for the Bay Area Rapid Transit District's (BART) management.  Switch components have little tolerance for wear and the rebuilding points by welding is not allowed.  Replacing these components places heavy burdens on maintenance budgets and requires a great deal of planning.  The time required for replacement is limited by available track occupancy time and support resources. Additionally, these components are not necessarily "off the shelf" items.  The lead times for procurement and delivery can be extensive.  Excessive wear results in restrictions to revenue operations, an unacceptable option in our environment.  Advance planning is crucial to providing the necessary resources for switch maintenance.  This paper describes the development of BART's standards for switch point and stock rail maintenance and the tools used for measurement.]]></description>

      <title>LIGHT RAIL VEHICLE/TRACK INTERFACE STUDY</title>
      <link>https://trid.trb.org/View/485775</link>
      <description><![CDATA[This paper describes a comprehensive study conducted for the Port Authority of Allegheny County (the Authority) in Pittsburgh, Pennsylvania.  The study represented a comprehensive review of wheel/rail interface and wear problems and their causes, and a review of applicable vehicle and track maintenance practices. The overall objectives of the study were to determine optimal configurations for those elements that affect the wheel/rail interface, determine measures to improve ride quality for passengers, provide recommendations to reduce wheel/rail noise, and to optimize equipment life and minimize maintenance and operating costs.  Specific tasks aimed at addressing the broad objectives and developing practical and effective solutions included a system condition investigation that evaluated some measured major components of the track structure.  Wheel/rail force measurements were collected and evaluated.  Both wayside and on-board vehicle measurements were collected and evaluated. A final report was submitted on the entire study and its findings, conclusions, and recommendations.]]></description>

      <title>ELECTRONIC PARTS CATALOG STANDARDS: A BETTER WAY</title>
      <link>https://trid.trb.org/View/485729</link>
      <description><![CDATA["Non-wrench" time for transit industry maintenance mechanics is staggering.  Studies show that up to 50% of their time is expended in non-repair activity.  Half of that time is expended researching repair and parts information.  This problem is being addressed in all industries with the deployment of electronic parts catalogs (EPCs).  EPCs offer enormous benefits to maintenance organizations.  Placing repair and parts information in the mechanic's hands "closes the loop" in maintenance operations.  Armed with quick and accurate repair information, repairs are done faster and with greater accuracy putting valuable assets back in service sooner.]]></description>

      <title>RESEARCH PAYS OFF: PREVENTING DERAILMENTS AT TURNOUTS</title>
      <link>https://trid.trb.org/View/577427</link>
      <description><![CDATA[Turnouts, where rail vehicles are physically moved from one track to another, and other special-trackwork areas are geometrically complex and pose a relatively high risk of train derailment.  From 1984 to 1996, approximately 200 derailments occurred at turnouts and other special-trackwork areas of rail-transit systems in the United States.  Under the Transit Cooperative Research Program, sponsored by the Federal Transit Administration and administered by the Transportation Research Board, a study was conducted to identify techniques that can be used to effectively reduce the potential for derailments on special trackwork.  Several types of turnouts on two transit systems were instrumented and monitored under a range of operating conditions.  A variety of devices and maintenance practices intended to reduce derailment risk were examined at the test locations, and their effectiveness in reducing the levels of detrimental forces was measured.  A computer simulation model was used to determine the potential effectiveness of proposed mitigation devices that had not yet been manufactured and thus could not be physically tested.  The adoption of comprehensive maintenance and inspection standards was found to be highly effective in reducing derailment potential.  Rail lubrication and the use of several devices, such as extended guard rails and switch-point protectors, were also found to be highly effective.  Use of the recommended devices and procedures would greatly reduce the incidence of derailments, thus increasing passenger and worker safety and yielding economic benefits through decreased maintenance costs and downtime and an increase in the service life of trackwork components.]]></description>

      <title>USER'S GUIDE: AUTOMATED RAILROAD TRACK INSPECTION</title>
      <link>https://trid.trb.org/View/478866</link>
      <description><![CDATA[Automated railroad track inspection can be used to supplement a track inspector's walking inspection for a comprehensive railroad track evaluation.  A track geometry vehicle can automatically measure track geometry parameters such as gauge crosslever, superelevation, alignment, profile, warp, and curvature. The measurements can be compared to maintenance standards and used to make a defect listing or exception report.  An internal rail defect vehicle uses ultrasonic testing equipment to detect internal rail flaws such as transverse fissures and vertical or horizontal split heads.  These internal rail flaws are typically not visible to the naked eye and can lead to a rail break and cause a train derailment.  This report includes discussions of the description, application, benefits, limitations, costs and recommended uses for automated railroad track inspection.  Model specifications for automated track geometry inspection and internal rail defect testing are also provided in the appendix of this report.]]></description>

      <title>DERAILMENT OF TRANSIT VEHICLES IN SPECIAL TRACKWORK</title>
      <link>https://trid.trb.org/View/482987</link>
      <description><![CDATA[This digest provides a summary of the findings from Transit Cooperative Research Program (TCRP) Project D-2, "Derailment of Transit Vehicles in Special Trackwork", which was conducted by Zeta-Tech Associates, Inc.  This research, completed in 1996, recommended procedures to reduce derailment occurrences.  The following methods were found to provide a highly effective and economic means for reducing derailment potentials:  use of pre-point guards; use of point protectors; adoption of comprehensive maintenance and inspection standards; use of lubrication; use of spring frogs; use of fully gauge plated switch-point areas; use of spiral switch points; and use of house-top point guards.]]></description>
