      <title>BASIC SKILLS DEVELOPMENT TRAINING PROGRAM. A DEMONSTRATION PROJECT FOR TRANSIT INDUSTRY PERSONNEL. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275713</link>
      <description><![CDATA[This report contains the results of a pilot demonstration for the Transit Basic Skills Development Training Program for which UMTA provided funding.  Planning and preparation phases for the program commenced September, 1983.  Actual participant training began February, 1984 and ended September, 1984.  During that time, which covered approximately seven (7) months, two hundred-fifty (250) Regional Transit Authority participants from four (4) local League affiliate areas enrolled in and met requirements for completion of the program.  The primary objective of the program was to address the basic skill needs of trainees and workers seeking employment advancement within the transit industry.  Further, it was to offer program participants an opportunity to move into areas of high technology.  In this capacity, the program provided remedial training to improve basic skills in the areas of reading and math to those individuals wishing to increase their critical basic skills at least four (4) grade levels.  The average learner received between eighty (80) and one hundred-twenty (120) hours of instruction in Reading Comprehension and Math Computation.  Of the two hundred-fifty (250) participants, approximately twenty applied for and were accepted at institutions of higher learning; forty (40) prepared for the High School Equivalency examination (GED) and more than seventy-five (75) were scheduled for promotional exams within their respective transit authorities.]]></description>

      <title>VALUE ENGINEERING STUDY: CROSS STREET BUS MAINTENANCE AND STORAGE FACILITY. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275711</link>
      <description><![CDATA[The purpose of the work effort was to test the applicability of Value Engineering Techniques on the design of the Greater Bridgeport Transit District's Bus Maintenance and Storage Facility.  Methods as approved by the Society of American Value Engineers (SAVE) were used to determine if less costly methods could be used in the construction of the Facility without affecting the Facility's function.  The Value Engineering Review of Bridgeport's Bus Maintenance and Storage Facility identified fifteen cost savings measures of which ten were implemented-saving an estimated $1,472,938 on the construction budget and $714,107 on the life of the Facility.  The Transit District's staff evaluation of the Value Engineering review rated the usefulness of Value Engineering in the design process very high and would recommend its use by other Transit Properties.]]></description>

      <title>EMERGENCY ALARM SYSTEMS: IMPROVED EMERGENCY ALARM/RESPONSE SYSTEM. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275709</link>
      <description><![CDATA[The purpose of the Emergency Alarm Systems Study is to provide management and supervisory personnel with the background of the bus emergency alarm system of the Metropolitan Transit Authority of Harris County, Texas, and problems associated with the system's use. METRO is used as the basis of this study as its systems and problems are typical of many urban bus systems. This report provides a perspective on emergency alarms as used by transit properties in general. It describes the range of problems involving the use of alarm systems and further addresses the methods and forms of procedures to help remedy the problem of alarm misuse. It examines transit security problems relating to emergency alarms, including false alarms, malfunctions, misuse of the alarm system and alarm system training. It is an effort to understand the nature and extent of the problem and to develop a strategy to increase the efficiency of the emergency alarm system and thereby enhance the safety of mass transit employees and patrons. The report points out that the effectiveness of emergency alarm systems linking buses to police and security support is seriously hampered by a high percentage of false or misused alarms. Research done for this report and elsewhere indicates that human error and misunderstandings caused by a lack of training are the greatest problems in alarm misuse. To gain an overview of emergency alarm systems, the Houston (Harris County) METRO system was evaluated and visits were made to four transit properties. Nine properties were contacted by telephone. Contacts were also made with several nontransit organizations, both government and private firms in order to learn what percentage of the emergency alarms they deal with are false alarms.]]></description>

      <title>BARRIERS TO PRIVATE SECTOR PARTICIPATION IN PUBLIC TRANSPORTATION. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275660</link>
      <description><![CDATA[This is a detailed examination by the New York Department of Transportation of barriers to contracting out of public transportation service or its support functions.  It includes an examination of the potential relationship between the private sector and various kinds of services, reviews several key barriers to private sector involvement, and explores its tentative conclusions through three case studies.  The study highlighted a wide variety of obstacles to the contracting process, originating at all levels of government.  These include lack of private involvement in mandated planning processes; the Section 13(c) labor protections; attitudes of local officials; state entry, exit, and tariff regulations; insurance and safety regulations; state legislation mandating particular institutional arrangements; administrative burdens resulting from federal or state regulations; restrictive local ordinances; a lack of private operators to bid; and the initiation of contracts that are negotiated, not bid.  It acknowledges some current UMTA actions to address the Federally originated barriers.  Most of the material appears to have broad applicability, but some of the discussions of state laws and regulations are specific to New York.  Some case studies in various New York counties are included.]]></description>

      <title>STARS AC PROPULSION PROJECT. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275656</link>
      <description><![CDATA[This report describes the design, manufacture and testing of a propulsion system for passenger rail application utilizing variable-voltage, variable-frequency (VVVF) inverter and a squirrel cage induction motor, along with associated microprocessor control circuitry. Novel developments in this propulsion system include the use of gate turn-off thyristors (GTOs); advanced semiconductor cooling methods; and multiple microprocessor, direct digital control. The rationale behind this development includes several factors: reduced maintenance and improved reliability associated with brushless AC motors and solid state electronics; improved energy efficiency due to elimination of series resistors; and high regeneration capability, further reducing energy usage. A net reduction in life cycle cost is predicted due to these factors when compared with conventional cam-controlled, series resistance DC propulsion systems. The report describes the six candidate systems studied, and explains the selection and design of the chosen system. Test data from a full scale laboratory model is included, along with studies of reliability, maintainability, safety, energy usage and life cycle cost.]]></description>

      <title>SUBWAY ENVIRONMENTAL SIMULATION PROGRAM AND SUBWAY ENVIRONMENTAL DESIGN HANDBOOK VALIDATION THROUGH FIELD TESTING. PART II OF IV: COMPUTER SIMULATION PROGRAMS. FINAL REPORT</title>
      <link>https://trid.trb.org/View/275655</link>
      <description><![CDATA[This technical report is Part II of IV of a project to validate by field tests specific portions of the Subway Environmental Simulation (SES) Computer Program and the Subway Environmental Design Handbook (SEDH) as they relate to underplatform exhaust systems; train-borne, naturally-convected resistor grid banks; stratification of air in high domed-roof subway stations; gravity-type, station dome relief vents; and the heat sink effect in stations. This report covers the description of the computer simulation programs being utilized; sources of program input data including data from previous field testing; typical computer input and output data; and specific comparisons of field-measured and computer-simulated data relative to train car resistor grid temperatures and station platform ambient air temperatures. General correlation was found between the measured and simulated resistor grid temperatures with the measured temperatures ranging to 20% below the simulated temperatures for current operating conditions. For 1990 conditions (higher train speeds, shorter station dwell times), the maximum difference reduced to about 15%. Less than a degree difference was found at one station between average field-measured and computer-simulated platform air temperatures. At a second station, the difference was five degrees with the measured temperature being the higher. Recomendations will be included in the final report.]]></description>

      <title>EXTREME CONDITIONS IMPACT ON RAPID TRANSIT SYSTEMS: EFFECT OF AUTOMATIC TRAIN CONTROL. FINAL REPORT</title>
      <link>https://trid.trb.org/View/274371</link>
      <description><![CDATA[Automatic Train Control (ATC) has gained wide acceptance and is presently used in all aspects of rapid rail operations. Because ATC has limited range of detection, conditions outside those limits might present hazards to transit system operation.  With a trend toward less human involvement in the actual operation of rapid rail vehicles, questions have been raised about train safety under ATC failures especially under extreme environmental conditions.  This report examines the impact of extreme environmental conditions and (ATC) failures on rapid rail system safety and makes recommendations to lessen their impact.  The environmental conditions covered in the report are:  high winds, floods, heavy ice and snow and sub-freezing temperatures as well as lightning.  In addition, fires and emergency egress procedures were analyzed in this investigation and recommendations were developed to lessen the consequences of fires and to expedite passenger evacuation procedures. Overloading, a situation frequently faced by rapid rail transit properties, was also examined to determine its impact on train safety and operation.]]></description>

      <title>RAILBUS DEMONSTRATION PROJECT EVALUATION REPORT. FINAL REPORT</title>
      <link>https://trid.trb.org/View/274366</link>
      <description><![CDATA[The City of Kenner, LA., and the New Orleans Regional Transit Authority sponsored a 3-week commuter rail service demonstration of a Railbus built by Associated Rail Technologies (formerly BRE-Leyland) between Kenner and downtown New Orleans.  The Railbus is a diesel self-propelled rail passenger car that may be operated in single or multiple units at up to 75 mph.  The unit seats 40 passengers and has a crush capacity of 70 persons.  The Railbus made 3 daily round trips between December 6, 1984 and January 11, 1985.  The Urban Mass Transportation Administration (UMTA) provided a grant to the RTA for an evaluation of the demonstration.  The Railbus ran on 11 miles of Illinois Central Gulf Railroad track (shared with AMTRAK passenger and Louisville and Nashville Railroad freight trains).  A shuttle bus connected New Orleans Union Passenger Terminal with various downtown locations as a convenience to Railbus passengers.  The operating experience was considered successful, and few problems were encountered.  The report provides details on the cost of the project, ridership, trip purpose, mechanical problems of the vehicle, operations. etc.]]></description>

      <title>TRAINERS' GUIDE: CASE STUDIES. FINAL REPORT</title>
      <link>https://trid.trb.org/View/274364</link>
      <description><![CDATA[This Guide is a component of a training program titled "Employing Handicapped Persons in the Transit Industry". The program was developed under contract DTUM60-80-C-72042, Project MA-06-0105, "Joint Transit Industry Employment and Training Project for the Handicapped." It was later revised under Contract DTUM60-83-C-71228, Project MA-06-0149, "Hiring Handicapped Persons-A Training Demonstration Project for the Transit Industry." This Trainers' Guide contains instructions, eleven case studies and a role play exercise for use by transit agencies and other interested organizations when training personnel professionals, EEO staff, managers, supervisors, and/or anyone who has decision making authority in the training and accommodation of workers with disabilities. The case studies and role play exercise are illustrative of the types of problems that confront persons with disabilities in securing jobs and the issues faced by personnel decision-makers and supervisors who may be dealing with disabled employees. The situations that form the basis of these exercises reflect actual policies and practices that were in effect in the public transit industry.]]></description>

      <title>SUPPLEMENT TO NATIONAL URBAN MASS TRANSPORTATION STATISTICS, 1981 SECTION 15 REPORT</title>
      <link>https://trid.trb.org/View/274344</link>
      <description><![CDATA[The Surface Transportation Assistance Act of 1982 amended the Urban Mass Transportation Act in part by adding two new grant programs:  Section 9 provides funds for capital, operating, and certain other types of assistance beginning in FY 1983; Section 9A is a one-year program for FY 1983 which may be used for all purposes of Section 9 except operating assistance.  Funds for both programs are apportioned to urbanized areas on the basis of statutory formulas incorporating:  population and population density as enumerated by the 1980 U.S. Decennial Census; and (only for urbanized areas with populations of 200,000 or more) various transit operating statistics as contained in the Section 15 data base.  Because of the time required for reporting, validating, and publishing these data, there is a two-year lag between the Section 15 reporting year and the fiscal year for which funds are being apportioned.  This Supplement contains the transit operating statistics used in computing the FY 1983 Section 9A apportionments.  These statistics are derived from the 1981 Section 15 Annual Report, and from supplemental 1981 Section 15 reports submitted by certain transit systems.  These systems either had not been subject to the Section 15 reporting requirement, or had not originally reported certain eligible data.]]></description>
