Abstract A major output of the Systems Operations Studies (SOS) -- one segment of the UMTA Automated Guideway Transit Technology (AGTT) program — is a set of compre- hensive computer models which support the analysis of automated guideway systems. The purpose of this report is to present a general procedure for using the SOS software to analyze AGT systems. Data to aid the analyst in specifying input information, which is required as input to the software, are summarized in appendices. For the most part, the data are based on analyses of information derived from existing and proposed systems during the SOS program. The procedure described in this report is based on experience gained during the SOS program and from other applications of the SOS software. 17. Key Words 18.

In order to maximize the benefits resulting from the availability of these models, GM Transportation Systems Division (GM TSD) was awarded a contract by the Transportation Systems Center of the U.S. Department of Transportation. The objectives of this effort are to enhance the usefulness of the AGTT-SOS software through continued research and development activity, to increase user familiarity of, and confidence in, the software through information dissemination workshops and validation, and to extend the guideline standards and requirements for analysis of AGT systems. This report presents a general procedure for using the SOS software to analyze AGT systems. The procedure is based on experience gained from actual use of the software during the System Operations Studies and other applications of the software. Data to aid the analyst in specifying input information are summarized in appendices. This document was prepared under the direction of the Extended SOS Program Manager at GM TSD, James F. Thompson. Final preparation of the report was the responsibility of Ronald A. Lee of GM TSD. James D. Boldig, Michael J. Rizzuto, and Gary Sullo contributed to the report in the areas of system availability, station design, and system costs, respectively.

    The Linguistic Expression of Affective Stance in Yaminawa (Pano, Peru) By Kelsey Caitlyn Neely A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Linguistics in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Lev D. Michael, Chair Professor Eve Sweetser Professor Justin Davidson Summer 2019 Copyright by Kelsey Caitlyn Neely Abstract The Linguistic Expression of Affective Stance in Yaminawa (Pano, Peru) by Kelsey Caitlyn Neely Doctor of Philosophy in Linguistics University of California, Berkeley Professor Lev D. Michael, Chair This dissertation explores affective expression in Yaminawa, a Panoan language ofPe- ruvian Amazonia. In this study, ‘affect’ is used to refer broadly to the English language concepts of ‘emotion’ and ‘feeling’. Affective expression is approached as an interac- tional phenomenon and it is analyzed in terms of affective stancetaking, i.e., the way speakers position themselves to objects in the discourse as well as their interlocutors via linguistic performance. This study considers affective resources at the levels of the lex- icon, morphology, prosody, acoustics (voice quality, speech rate and volume, etc.), and interactional features (turn duration, complexity of backchannels, etc.). This study contextualizes affective expression in Yaminawa with a detailed descrip- tion of Yaminawa ethnopsychology and the lexical resources that describe affective states, as well as behaviors and bodily sensations that are associated with particular affects by the Yaminawa. Using methods from Cognitive Anthropology, I investigate the ways that native Yaminawa speakers categorize emotion terms, and show that prosociality vs. anti- sociality is a major cultural axis along which emotion terms are conceptually organized.

Kieffer, Secretary The Advanced Transit Association exists to focus attention on unmet urban transportation needs and the ways in which advanced transit concepts can help satisfy them. One of these unmet needs results from the gap between the poor quality of transit service in medium and low-density locations within urban areas and the availability of transit technology that can furnish high quality service at affordable costs. ATRA’s objectives, with particular respect to this report, are to: § Focus public attention on the medium and low density transit problem and the ways in which advanced transit concepts can help solve it; § Seek wider agreement on the main features that advanced transit should possess to cope with this problem, including

    October 30, 2009 Evolution of Personal Rapid Transit J. Edward Anderson, Ph.D., P. E. PRT International, LLC Abstract The paper reviews the evolution of the PRT concept from its modern beginning in 1953. The early inventors, the projects, and the response of government are discussed. PRT ac- tivity diminished to almost nothing by 1980, but then revived strongly as a result of activ- ity by the Northeastern Illinois Regional Transportation Authority. Their interest ignited enthusiastic activity on a growing front to the point that today one can truly say that the concept is coming of age.

Some of the ideas embodied in PRT go back even to the last century, but were premature, briefly flowered and died. Since 1953 the evolution has been continuous, though fluctuating − continuous per- haps mainly because the concept of automatic control, essential to PRT, had been firmly estab- lished by the early 1950’s; and fluctuating for reasons that had little or nothing to do with the technical feasibility of the idea or its potential value to urban society.

    AHS Comparable Systems Analysis

    Calspan Task G Page 1 Precursor Systems Analyses of Automated Highway Systems RESOURCE MATERIALS AHS Comparable Systems Analysis U.S. Department of Transportation Federal Highway Administration Publication No. FHWA-RD-95-120 November 1994 Calspan Task G Page 2 FOREWORD This report was a product of the Federal Highway Administration’s Automated Highway System (AHS) Precursor Systems Analyses (PSA) studies. The AHS Program is part of the larger Department of Transportation (DOT) Intelligent Transportation Systems (ITS) Program and is a multi-year, multi-phase effort to develop the next major upgrade of our nation’s vehicle-highway system. The PSA studies were part of an initial Analysis Phase of the AHS Program and were initiated to identify the high level issues and risks associated with automated highway systems. Fifteen interdisciplinary contractor teams were selected to conduct these studies. The studies were structured around the following 16 activity areas: (A) Urban and Rural AHS Comparison, (B) Automated Check-In, (C) Automated Check-Out, (D) Lateral and Longitudinal Control Analysis, (E) Malfunction Management and Analysis, (F) Commercial and Transit AHS Analysis, (G) Comparable Systems Analysis, (H) AHS Roadway Deployment Analysis, (I) Impact of AHS on Surrounding Non-AHS Roadways, (J) AHS Entry/Exit Implementation, (K) AHS Roadway Operational Analysis, (L) Vehicle Operational Analysis, (M) Alternative Propulsion Systems Impact, (N) AHS Safety Issues, (O) Institutional and Societal Aspects, and (P) Preliminary Cost/Benefit Factors Analysis. To provide diverse perspectives, each of these 16 activity areas was studied by at least three of the contractor teams. Also, two of the contractor teams studied all 16 activity areas to provide a synergistic approach to their analyses.
