      <title>A multi-criteria decision support methodology for implementing truck operation strategies</title>
      <link>https://trid.trb.org/View/1249934</link>
      <description><![CDATA[In this study, the authors propose a multi-criteria decision support methodology that enables the prioritization of potential alternative transportation systems operation strategies. The methodology's primary feature is that it allows for the simultaneous consideration of economic, public, and private sector standpoints by policymakers. A case study involving truck operations is used to demonstrate the effectiveness of the methodology. The case study examines three forms of left lane truck restrictions along a corridor with one of the highest volumes of truck traffic in the United States. Cost to the public sector is the economic criterion; the four criteria for truck impacts on the transportation system are: traffic congestion, safety hazards, air pollution, and pavement damage. Because of their potential impact on profitability, reliability and productivity are included as metrics for the private sector. Both qualitative and quantitative analyses are conducted. Survey data from two groups of trucking experts (classified as public agency and transportation industry professionals) were collected.  Performance measurements for quantitative impacts were produced using a micro traffic simulation model. The authors suggest that a rational argument for prioritizing potential alternative truck strategies is supported by this methodology.]]></description>

      <title>An Inside Look at Active Transportation in Bogotá: A Qualitative Study</title>
      <link>https://trid.trb.org/View/1244339</link>
      <description><![CDATA[The health benefits of physical activity are well documented in scientific literature. Bicycling for transportation is a modality of physical activity that people can incorporate easily into their daily lives. A qualitative study using 11 semi-structured individual interviews and 5 focus groups was conducted among 31 male and 13 female adult residents of Bogotá, Colombia in 2006. The study explored barriers and facilitators of bicycle use for transportation purposes. People were selected based on socioeconomic status, age, and gender. Thematic analysis complemented with thematic network analysis was used to analyze the data. Six main themes emerged from the study: (1) general acknowledgment of individual and collective benefits of bicycle use; (2) built environment conditions were linked with bicycle use; (3) some social factors affect bicycling negatively; (4) people perceived conflicts over public space related to the use of bike-paths;( 5) general negative public perception of bicyclists; and (6) gender differences influence patterns of bicycle use. The findings from this qualitative study show that various social and physical barriers must be addressed to increase bicycle use as a means of transportation in Bogotá.]]></description>

      <title>Creating Customer Value and Next-Generation Stations</title>
      <link>https://trid.trb.org/View/1104255</link>
      <description><![CDATA[Rail station user profiles have been changing gradually over time. Such qualitative change needs to be predicted and means to meet new customer requirement added to station spaces provided to create further customer value. "Market-in" is the general concept current qualitative change efforts are using. "Market-in" allows a company to gain an understanding of rail station user needs in order to strive to provide what users want. The author examines "market-in" thinking in terms of safety, security, the environment and resources, the relationship between the station and surrounding community, service provider role, conceptual viewpoint, technology, lifestyle continuity, total design, and additional customer value creation. The author concludes that in creating customer value, the ability to continue providing service as usual without change is an important value creation aspect.]]></description>

      <title>Liberalization of Maritime Cabotage. Lessons from the Greek Experience</title>
      <link>https://trid.trb.org/View/889589</link>
      <description><![CDATA[This paper describes how the development of coastal transport services has been an issue of major importance and captured the interest of both the Greek State and its citizens for many years.  Indeed, Greek coastal transport has played a crucial role in national cohesion in various respects.  From a geographical perspective coastal transport connects mainland with islands. From an economic and social perspective sea ferries services influence the population levels of the islands, provide opportunities for economic development, and enhance islanders’ quality of life. This paper analyses the reasons that have led to almost eternal difficulties in developing an efficient and effective Greek coastal shipping system. The analysis focuses on the interplay of oligopolistic market features and ineffective state policies that has resulted in an unstable coastal market and has undermined the quality of the supplied shipping services. In particular it discusses the role of an intervening state in shaping the market (i.e. by controlling entry, fares, and safety rules and intervening in routes, manning, duration of employment) in absence of the user of the services. The paper provides a qualitative assessment of the liberalization of the coastal market. Greek island cabotage was opened up to European competition in 2002. Greece sped up its decision to liberalize its coastal services since according to the European Regulation 3577/92, its exemption was prolonged until 2004. The paper discusses research findings on market concentration and user satisfaction vis-à-vis market characteristics and (de)regulatory developments, aiming to conclude on the potential of a framework that would satisfy the users of a service with general economic interest.]]></description>

      <title>Measuring the Impacts of Singapore’s Area License Scheme</title>
      <link>https://trid.trb.org/View/843771</link>
      <description><![CDATA[The various impacts of Singapore’s Area License Scheme are presented in this paper in terms of a wide variety of variables that are measured on different scales, or in some instances qualitatively assessed. The increased case of crossing streets for pedestrians, cleaner air, and people’s perception that downtown Singapore has been improved are important benefits, but do not lend themselves to evaluation in economic terms without strong and arbitrary assumptions. The impact of the scheme on business was identified only qualitatively, not only because of a lack of statistics but perhaps even more importantly because of the impact of the Area License Scheme could not be quantitatively separated from the effects of the general recession or from the existing trend toward decentralization.]]></description>

      <title>Material and Structural Crashworthiness Characterization of Paratransit Buses</title>
      <link>https://trid.trb.org/View/841587</link>
      <description><![CDATA[A comprehensive experimental material characterization and full-scale testing of structural connections of paratransit buses is presented in this paper. Structure-property relations were quantified for the constitutive material models used for finite element (FE) simulation-based crashworthiness research of paratransit buses. Several structural materials used by the paratransit bus industry were identified, and coupon size specimens were tested. A dynamic wall panel test with an impact hammer provided validation data for the FE simulations. In addition, quasi-static laboratory tests of standard connections between the walls, floor, and the roof of a selected paratransit bus were performed. In addition to FE model validation, the connection testing allowed for thorough qualitative assessment of connection design, which resulted in improved crashworthy connection details. The experimental materials characterization and validation protocol described in this paper is consistent with the draft of the crash and safety standard for structural assessment of paratransit buses in the state of Florida. This roadmap is intended to be used for crashworthiness evaluation of future paratransit buses.]]></description>

      <title>Synthesis of Quantitative and Qualitative Evidence for Accident Analysis in Risk-Based Highway Planning</title>
      <link>https://trid.trb.org/View/788485</link>
      <description><![CDATA[Accident analysis involves the use of both quantitative and qualitative data in decision-making. The aim of this paper is to demonstrate the synthesis of relevant quantitative and qualitative evidence for accident analysis and for planning a large and diverse portfolio of highway investment projects. The proposed analysis and visualization techniques along with traditional mathematical modeling serve as an aid to planners, engineers, and the public in comparing the benefits of current and proposed improvement projects. The analysis uses data on crash rates, average daily traffic, cost estimates from highway agency databases, and project portfolios for regions and localities. It also utilizes up to two motivations out of seven that are outlined in the Transportation Equity Act for the 21st Century (TEA-21). Three case studies demonstrate the risk-based approach to accident analysis for short- and long-range transportation plans. The approach is adaptable to other topics in accident analysis and prevention that involve the use of quantitative and qualitative evidence, risk analysis, and multi-criteria decision-making for project portfolio selection.]]></description>

      <title>Valuing Urban Bus Attributes: An Experience in Kolkata</title>
      <link>https://trid.trb.org/View/783172</link>
      <description><![CDATA[The article presents the marginal willingness-to-pay (WTP) estimates for various qualitative and quantitative attributes of travel with reference to the bus transportation system in Kolkata City, India.  A stated choice experiment is designed to capture the responses for estimating marginal WTP values for various attributes.  WTP values are estimated separately for commuting and noncommuting trips.  The effects of model specification and socioeconomic parameters on WTP values are also studied.  Estimates from standard multinomial logit (MNL) and different random parameter logit (RPL) models indicate that WTP values vary with model specification.  In the process of developing RPL models, successful application of sparsely used constrained triangular distribution is also demonstrated.]]></description>

      <title>OVERVIEW OF PREFERENCE BASED HEALTH STATUS MEASURES</title>
      <link>https://trid.trb.org/View/644445</link>
      <description><![CDATA[When evaluating injury outcomes, measures are needed that contain a qualitative judgment regarding the relative importance to the individual or to society of the various aspects of function and disability that may be affected because of the outcome under evaluation.  These qualitative judgments are referred to as "preferences."  Preference-based measures reflect the relationship between impairment, functional limitation, and disability and the individual's (or society's) overall level of well-being and satisfaction with life.  This paper focuses on the measurement of these qualitative assessments.]]></description>
