Performance indicators for an objective measure of public transport service quality
The measurement of transit performance represents a very useful tool for ensuring continuous increase of the quality of the delivered transit services, and for allocating resources among competing transit agencies. Transit service quality can be evaluated by subjective measures based on passengers’ perceptions, and objective measures represented by disaggregate performance measures expressed as numerical values, which must be compared with fixed standards or past performances. The proposed research work deals with service quality evaluation based on objective measures; specifically, an extensive overview and an interpretative review of the objective indicators until investigated by researchers are proposed. The final aim of the work is to give a review as comprehensive as possible of the objective indicators, and to provide some suggestions for the selection of the most appropriate indicators for evaluating a transit service aspect
A service quality experimental measure for public transport
In this paper the importance of service quality attributes for public transport is estabilished by
Importance Value calculation. Attribute weights (IV) are calculated by a specific empirical procedure in
which a rate is assigned to each attribute according to the preferences of passengers.
Finally, a Service Quality Index (SQI) for measuring the effectiveness of supplied services is calculated
according to the main service quality attributes and their weights. This index can be useful to planners to
choose more appropriate public transport agencies. Futhermore, it can be used by transport agencies to
improve supplied service regarding more convenient service quality attributes
Willingness-to-pay of public transport users for improvement in service quality
In this paper, passenger willingness-to-pay (WTP) for improving the quality levels of a bus service is
examined. Specifically, the objective of this research is to provide a tool for evaluating passenger
willingness-to-pay by considering some qualitative service aspects, in addition to the traditional
quantitative service aspects like travel time and cost. The adopted methodology is built on the calibration
of behavioural models based on user choices. The WTP values are obtained as marginal rates of
substitution between some service quality attributes and travel cost at constant utility. For this purpose,
Multinomial and Mixed Logit models are introduced. The models were calibrated by using the data
collected from an SP experiment in which each user makes a choice between an alternative representing
the current service and two alternatives representing hypothetical bus services. In order to take into
account the randomness of the estimated WTP, the limits of the confidence intervals are calculated
Transit Passenger Perceptions: Face-to-Face Versus Web-Based Survey
In this paper, face-to-face and web-based survey methods of collecting transit passenger perception data are compared using two transit customer satisfaction survey tools. Multivariate statistical analyses are applied to determine the differences between the two surveys. Some differences in behavior and attitudes of web survey respondents compared with those from a face-to-face survey are found. The results can help transit agencies manage their bus services to improve passenger satisfaction and service quality
The Breath of Sense: Language, Structure, and the Paradox of Origin
Within contemporary analytic philosophy, at least, varieties of “naturalism” have attained a widespread dominance. In this essay I suggest, however, that a closer look at the history of the linguistic turn in philosophy can offer helpful terms for rethinking what we mean in applying the categories of “nature” and “culture” within a philosophical reflection on human life and practice. For, as I argue, the central experience of this history—namely, philosophy’s transformative encounter with what it envisions as the logical or conceptual structure of everyday language – also repeatedly demonstrates the existence of a fundamental aporia or paradox at the center of the claim of language upon an ordinary human life. I discuss the occurrence of this aporia, and attempts to resolve it, in the philosophical writing of Carnap, Quine, Wittgenstein, Heidegger, and McDowell. I conclude that the prevailing naturalistic style in analytic philosophy, whatever its recommendations, is itself the outcome of an unsuccessful attempt to resolve the central aporia of twentieth-century philosophical reflection on language. Closer attention to this aporia reveals that language, as we find it in both theoretical and everyday reflection, is in the most important sense, neither essentially “natural” nor “cultural.

how drivers characteristics can affect driving style
Abstract Driving style concerns the way a driver chooses to drive, and depends on physical and emotional conditions of the driver while driving. In order to validate this hypothesis, we propose a Structural Equation Modelling (SEM) aimed to investigate on the relationship among driving style and drivers' characteristics such as somatic, behavioural and emotional conditions. Drivers' conditions include tiredness, sleepiness, sickness, gloom, worry, nervousness, boredom, and anger. In the proposed model, driving style is considered as an endogenous latent construct, while drivers' characteristics were considered as exogenous. Driving style is defined by means of a judgement expressed by the driver on a scale ranged from aggressive to cautious. In addition, a more reliable definition of the driving style is determined through an objective measure derived from cinematic parameters. We addressed to a sample of drivers a questionnaire aimed to collect information about their conditions while driving and the judgement about their driving style. Each driver registered the same path run in different days (more than thirty paths for each driver, in average), and complete the questionnaire for each path. This permits to observe the possible changes of drivers' driving style as a function of the different physical and emotional states that drivers present in different days
multilevel comprehensive evaluation of the railway service quality
Abstract A multilevel fuzzy synthetic evaluation model to evaluate the railway service quality is proposed based on the fuzzy theory. An evaluation indicator system with three grades evaluation indicators is established, and their weights are determined on the basis of opinions expressed by interviewed passengers. Railway service quality is evaluated by the value of a comprehensive satisfaction degree. The method can provide not only for the passengers' overall satisfaction degree on the railway service quality, but also the passengers' satisfaction degree on some primary evaluation indicators. According to the evaluation results, we found interesting differences of perception of the service among the users
