Previous research has shown that low-cost carriers (LCCs) may stimulate traffic at an airport by offering low fares. Using passenger survey data from the Washington–Baltimore region’s three airports, we find that the benefits of LCCs to airports extend beyond the traffic generated directly by the LCCs through their low fares. In addition, we find that the mere presence of an LCC at an airport can attract passengers, even to competing carriers. These “halo effects” from LCC presence increase the significance to airport managers of attracting LCCs in order to generate passenger demand.  相似文献

Evaluating the resources in a tourism destination is one of the previous tasks in the development of its comprehensive planning. There are many criteria to use in order to evaluate tourism resources; but, independently on the number of attributes considered the fact is that not every criterion is equally important in the process of evaluation and ranking of the tourism potential of a destination's resources. In contrast to other well-known methodologies, the aim of this paper is to propose a methodology to weight qualitative and hierarchical evaluation attributes by estimating a discrimination parameter. In this research, an item response theory (IRT) model is used, the graded response model, to estimate each attribute's discrimination coefficient. This parameter will be the basis to propose a weighting system for the entire set of attributes. Graded response model (GRM) will also allow establishing a hierarchy of resources by constructing a continuous latent scale, where it will be possible to position every analysed resource in the tourism destination. The applicability and robustness of the IRT methodology will be tested using data from rural tourism resources in the Spanish province of Cáceres.  相似文献

Published fares London–Amsterdam are used to examine the pricing practices of low-cost and legacy carriers when operating in a large and crowded market. We investigate two strategies of market segmentation involving the time before departure the ticket has been bought, inter-temporal segmentation, and the duration of the stay, implicit segmentation. We find inter-temporal price discrimination emerges as an important strategy for all pricing but the two legacy carriers involved, British Airways and KLM, differ in their use of stay restrictions; British Airways does not assign a specific role to the duration of stay, while KLM make use of such rules extensively in price setting.  相似文献

This paper analyzes the spatial–temporal evolution of the attractiveness of a country’s gateway for its international trade, using Shanghai as an example. The attractiveness is regressed on the transportation facilities and geographical conditions. Seaport development is found to have a major positive impact, followed by inland waterway, highway, and airport development. These positive impacts decrease with the need for highway haulage and with the distance from Shanghai—showing an inverse U-shape distribution. Rail appears to have a U-shape distribution, implying a low application of multimodal transportation. A geographical pattern for the impacts of different transportation modes is delineated.  相似文献

We empirically study passenger modal-choice behavior to access an international hub airport, by using stated preference (SP) data and by constructing a binomial logit model. We found that passenger modal choice is affected by the service level of the access modes: travel time, travel cost, waiting time, and delay cost. The results also indicate that if passengers choose access mode in advance they consider service frequency: departure timing from home, and the arrival timing at the airport. Moreover, our results indicate that travelers’ willingness to pay for saving time differs by time of a day. They are apt to pay more in the morning than in the afternoon. These outcomes must contribute to improve the access flight service from local to hub airports to handle the needs of passengers.  相似文献

Most bicycle crash analyses are designed as explanatory studies. They aim to identify contributing risk factors and calculate risk rates based on – most of the time – highly aggregated statistical data. In contrast to such explanatory study designs, the presented study follows an exploratory approach, focusing on the absolute number of crashes. The aim is to reveal and describe patterns and dynamics of urban bicycle crashes on various spatial scale levels and temporal resolutions through a multi-stage workflow. Spatial units are delineated in the network space and serve as initial units of aggregation. In order to facilitate comparisons among regions and quantify temporal dynamics, a reference value of crash frequency is simulated for each unit of the respective spatial scale level and temporal resolution.For the presented case study, over 3000 geo-coded bicycle crashes in the city of Salzburg (Austria) were analyzed. The data set covers 10 years and comprises all bicycle crashes reported by the police. Distinct spatial and temporal patterns with clusters, seasonal variations, and regional particularities could be revealed. These insights are indicators for urban dynamics in the transport system and allow for further, targeted in-depth analyses and subsequent counter measures. Moreover, the results prove the applicability of the proposed multi-stage workflow and demonstrate the added value of analyses of small aggregates on various scale levels, down to single crashes, and temporal resolutions.  相似文献

This article investigates the degree of overlap among the different layers of circulation composing global maritime flows in recent decades. Mobilizing several methods originating from complex networks allows us to shed new light on specialization and diversification dynamics affecting the evolution of ports and shipping. The principal confirm the strong and path-dependent influence of multiplexity on traffic volume, range of interaction and centrality from various perspectives, such as matrices correlations, homophily, assortativity, and single linkage analysis. While the network grows and concentrates around large hubs over time, traffic distribution is also place-dependent due to the reinforced position of already established nodes.  相似文献

The construction of the fixed link between Denmark and Sweden will increase the accessibility between South Sweden and East Denmark dramatically. The vision is that the fixed link will span economic, administrative, institutional, technical, cultural and other barriers, and that the two separated urban systems (Greater Copenhagen and Malmö–Lund) can be integrated, opening up for new dynamics. The Öresund (Sound) area has the potential to develop into one functional metropolitan region constituted by flows, markets and terminals. The ambition is to lift Copenhagen to a higher position in the European urban hierarchy by this integration, the instrument being the 16 km long fixed link which will open in the year 2000.  相似文献

BackgroundA safe environment has been widely accepted as one of the most important walkability predictors. However, the relation between perceived safety and walkability has not been well established.AimsThis paper focuses on quantitative aspects of the relation between perceived safety and walkability, as well as examining spatio-temporal patterns of fear-related areas, with a special emphasis on gender differences among adolescents.Data and methodsData regarding walkability perception and safety perception was collected during a mapping exercise in primary and grammar schools in Banská Bystrica city (central Slovakia), with a final sample of 303 adolescents (13–16 years old, 54% girls). In the experiment, pre-prepared reply forms and maps divided into a square fishnet were used.ResultsRegardless of the time of day, girls felt less safe in public spaces than boys did, especially in the city centre. In general, fear-related spaces for boys were more dispersed than for girls, whose perceived risky areas were more compact and spatially concentrated. Girls' perception of walkability was more affected by feeling safe than that of boys, with fewer gender differences at night.ConclusionsBy mitigating and even eliminating threats observed by girls, gender differences in the perception of barriers to walking can be reduced.  相似文献

Space–time fixity constraint is an important concept in transport geography, but the influence of the built environment around both people’s residence and activity locations is not clear. Due to the housing reform and rapid suburbanization in China, various types of residential communities and diverse built environments coexist in the suburbs. Comparing how people’s space–time fixity/flexibility varies among different community types and built environments can thus enhance our understanding of the transition process in Chinese cities. This study investigates how space–time fixity/flexibility and their relationships with the built environment vary among different types of residential communities in Beijing suburbs. Activity-travel diary and 7-day GPS tracking data of 709 respondents in Shangdi-Qinghe area of Beijing collected in 2012 were used. We investigate how variations in space–time flexibility are associated with built environment factors and four different community types: danwei communities, commodity housing communities, affordable housing communities and relocated housing communities, controlling for personal, household and activity attributes. The results suggest the influences of the built environments at residential place and activity place are different, and the relationships between space–time fixity and the built environments of different community types are different. Space–time fixity is not so sensitive to the built environment for residents in danwei communities and affordable housing communities. Gender and age differences in space–time fixity are not consistent with what was observed in Western countries. This seems to reflect the influence of unique social, cultural and family norms in China.  相似文献

Rail users consistently perceive their risks from crime to be significantly higher than official statistics suggest, discouraging many from using rail transport. The aims of the paper include a discussion of Crime Prevention Through Environmental Design (CPTED) and current policy initiatives for reducing crime and the fear of crime on the railways. This exploratory study focuses on adult passengers' perceptions of crime and nuisance as they relate to the management, design and maintenance of railway stations and their immediate access routes. The study innovatively utilises interactive virtual reality (VR) scenes of `representative' stations as the environmental stimulus and concludes that such an approach provides an analytical and pragmatic framework for managers of railway stations that are unlikely to receive Secure Station accreditation.  相似文献

This paper estimates the willingness-to-pay for anticipated journey-time savings introduced by the Crossrail intervention in the London Borough of Ealing. Given Crossrail remains under construction, we estimate how the anticipated benefit of Crossrail's announcement enters the house price determination process. Anticipated journey-time savings should enter the home-buyer's pricing equation because these benefits are speculatively internalised even before the service becomes operational. Using a experimental method that accounts for the possibility of a spatial autoregressive process in housing values, we test the hypotheses that the announcement of a new commuter rail service generated a location premium, and that house price appreciation reflected proximity to Crossrail terminals. Our evidence suggests home-buyers significantly valued proximity to planned Crossrail terminals following the post-announcement period.  相似文献

Twentieth century citizen “revolts” against urban highway projects have influenced thinking about public transport (Toronto, Vancouver, New York), governance (Portland), and cycling (The Netherlands) to this day. Less is known, however, about how these emerge in developing countries, and what they can tell us about citizens’ role in innovation to achieve more sustainable transport systems. This case study examines a social movement that emerged in opposition to the country’s first major highway concession, in Santiago, Chile (1997), challenging and changing urban planning paradigms. In 2000, the anti-highway campaign founded a citizen institution, Living City (Ciudad Viva). Twelve years later, it has become a prize-winning, citizen-led planning institution.Although the role of citizen participation in improving transport systems has become increasingly recognized in recent years, it still tends to be rather ritualistic. This experience offers insight into how strategic approaches to participation can reinforce the role of self-organizing civil society organizations in introducing innovation into existing systems. Findings suggest that traditional large movements, which are mainly useful for one-way communication of information, require support from small groups able to deliberate in a transformative sense, with more attention paid to how new consensuses can be transmitted through the relational networks of those involved. Moreover, this experience suggests that thinking about citizens as planners in their own right, rather than as mere participants at specific points in a planning process, opens the way to more effective strategies for innovating in transport, to address the social, environmental, and other challenges humanity faces today.  相似文献
