Design of limited-stop bus service with capacity constraint and stochastic travel time

This paper develops a mathematical model for the optimal stopping design of limited-stop bus service, which allows each bus vehicle to skip some stops. To better reflect the reality, this paper considers the vehicle capacity and stochastic travel time. Also, vehicles are all allowed to skip stops whereas any stop is not allowed to be skipped by two consecutive vehicles. A hybrid artificial bee colony (ABC) and Monte Carlo method is developed to solve the optimal stopping strategy. Finally, the model and solution method are validated by a numerical example, and a sensitivity analysis is performed on the passenger demand.     

Analysis of user satisfaction to promote public transportation: A pattern-recognition approach focusing on out-of-vehicle time

Public transportation has been regarded as one of the most sustainable forms of transport, because of which local governments have put efforts in increasing the mode share of public transportation. Recently, not only level of service but also user satisfaction has been focused on for the assessment of transport policy; however, several points have been overlooked in previous research, such as attribute-based satisfaction, the relationship between level of service and satisfaction, and user expectation. This paper deals with these issues while assuming the heterogeneity of satisfaction, which is an indicator of perception. Out-of-vehicle times, particularly headway and access time, were selected in the analysis because they can affect travel behavior of current and potential public transportation customers. In this analysis, pattern-recognition models were applied, and public transportation users were segmented in terms of perception. The results suggest several notable recommendations for public transport policies and investigations.     

The spatial and temporal variation in passenger service rate and its impact on train dwell time: A time-series clustering approach using dynamic time warping

This study aims to improve the understanding of the underlying mechanism of passenger boarding and alighting processes, as well as its potential influence on train dwell time and train operation. Empirical data collected from one of busiest metro stations in Seoul, Korea, demonstrates the spatial and temporal variation in the passenger service rate, as a result of interference between boarding, alighting, and standing passengers. This study postulates that the level of interference can be associated with the train car occupancy and the proximity of train door to entry points, as waiting passengers tend to cluster near the platform entries. A unique temporal service rate curve is derived from each door location. We introduce Dynamic Time Warping for similarity assessment and clustering. It revealed four groups of train doors showing distinct shapes of curve from each platform. The first cluster includes the train doors located closest to the platform entry points where the initial service rate is drastically impeded by severe inference among passengers. The level of interference gradually diminishes as the door is located farther away from the entry points, but the overall service rate decreases as well. A passenger service time model is derived to include the cluster variable. To test its significance, the prediction capability of the model is presented with and without the cluster variable. The results of this study may be used to guide waiting passengers along the platform to minimize interference and to avoid serious disruption during passenger service time.     

Built environment diversities and activity–travel behaviour variations in Beijing, China

The association between built environment and travel behaviour has received considerable research attention in recent years. In an attempt to contribute to this growing literature, this paper investigates the connections between urban built environments and activity–travel patterns in Beijing, the capital city of China. We characterize the built environment in Beijing and establish associations between built environment and activity–travel behaviour in terms of car ownership, time spent for out-of-home activities, and daily trip frequencies and travel time. Activity diaries from 1119 respondents living in ten different neighbourhoods were collected by face-to-face interviews. A household-level structure equations model incorporating intra-household interactions is developed to analyse this data. The empirical results show that residents of different types of neighbourhoods in Beijing demonstrate significant differences in car ownership, time spent for out-of-home activities, trip rate, and travel time. Further, the characteristics of the built environment are found to have more significant impacts on the activity–travel behaviour of the male head than that of the female head.     

Hub competition and travel times in the world-wide airport network

The aim of this work is to measure the competition between airport hubs based on an analysis of travel times in the world-wide airport network. By considering the minimum travel time required to connect each pair of airports, it is possible to create new measures of hub competition, separating the effects of hub position and temporal coordination. This analysis was carried out at the global level, considering all 232 airports with more than 3 million seats yearly offered in departure flights in 2008, and also in relevant geographic markets. The results show a high level of competition among the most important world airports, but the major airports of Europe have a geographical advantage in relation to world markets over the major American and Asian airports. We also show that airports located in different continents often compete for the same origin–destination markets. Geographical position appears to be the most important variable explaining hub performance. Secondary hubs show a higher degree of specialization towards specific markets.

Exploring the interplay between the use of risk-related information,risk perception formation,and the stages of travel product consumption

This study examined using patterns of risk and warning-related information by backpackers who develop their own travel risk perceptions. It looked at the preferences of information sources and usage levels among Israeli backpackers. Using a simulating approach, interviewees were asked to report on their preference and usage patterns in four stages of the travel consumption sequence – (a) prior to choice of destination; (b) after choice of destination but before departure; (c) during the trip, and (d) after returning home. Based on a sample of 467 former backpackers, the study revealed that they use a relatively wide range of risk-related sources of information yet their preference and usage levels in those sources vary as they moved from one consumption stage to the other. The most innovative finding of this study is that unlike previous findings there was a significant and direct correlation between the level of risk-related information consumption and the backpackers’ level of risk perception in each of the tourist product consumption stages. Further research directions derived from these findings as well as management implications are provided.     

The access journey to the railway station and its role in passengers’ satisfaction with rail travel

This paper focuses on two lines of investigation with regard to access to railway stations in the Netherlands. Firstly, the profile of the access and egress modes on journeys to and from railway stations is analyzed. We also examine how the availability of car affects the mode choice on journeys to the station. Secondly, the effect of passengers’ perception of the station and of the journey to the station on the overall perception of traveling by rail is estimated. The results show that most of the passengers choose walking, bicycle and public transport to get to or from the railway station and that the availability of a car does not have a strong effect on the choice of access mode to the station. The quality of the station and the access/egress facilities was found to have an important effect on the general perception of traveling by rail.     

The impact of the Internet on human activity–travel patterns: analysis of gender differences using multi-group structural equation models

The widespread use of the Internet for conducting various types of activities may be leading to considerable change in people’s activity–travel patterns. Past studies, however, have left many issues unaddressed. Using an Internet-activity diary dataset and multi-group structural equation modeling, this study examines the complex interactions between different types of Internet and physical activities, with a special focus on gender differences and Internet maintenance and leisure activities. The results indicate that the impacts of Internet activities on people’s activity–travel patterns are significantly different across gender. In general, Internet use for maintenance purposes has a greater impact on women’s activity–travel in the physical world, while Internet use for leisure purposes affects men’s physical activities and travel to a greater extent. Further, breaking Internet activities down into different categories reveals some hidden patterns that would not have been detected if these different types of Internet activities were lumped together as a single category.     

Time use, travel behavior, and the rural-urban continuum: results from the Halifax STAR project

This paper considers variations in time-related aspects of travel behavior along the urban-rural continuum, using the four categories of inner city, suburbs, inner commuter belt (ICB), and outer commuter belt (OCB). It employs geo-coded and GPS-validated data from the STAR survey conducted in the county-sized regional municipality of Halifax, Nova Scotia. Many significant inter-zonal differences are identified, and most travel variables are characterized by progressive urban-to-rural gradients, with large differences between inner-city and outer-commuter values. A clear break between city and country is seldom evident, however. Inner-city residents make most trips, but have trips of shortest duration, and spend least time in travel. Residents of the commuter belts spend most time in travel, and have trips of longest duration. While long trips and much driving were expected in commuter zones, there are significantly fewer trips in the OCB, which we attribute to lack of need, lack of opportunities, and adjustments in discretionary behavior.     

Going steerage on Ryanair: cultures of migrant air travel between Poland and the UK

One of the most high profile migration movements to the UK in recent years has undoubtedly been that of A8, and mainly Polish, newcomers following the 2004 expansion of the EU. Accompanying, and perhaps fuelling, this increase in mobility has been a substantial rise in low cost air travel provision. The UK Civil Aviation Authority and the Civil Aviation Office of the Republic of Poland statistics testify to the expansion in passenger numbers between Poland and the UK since 2004, with Ryanair being one of the main carriers. Although other modes of transport, such as coach and car travel, are still important, in some senses these Ryanair flights define this new migration. Taking as a starting point that airports and airplanes are social and cultural venues in their own right, and that migration journeys are themselves at the heart of the migration experience, this article uses interviews with Polish migrants in the UK to consider this low cost air travel for migration in more depth. Firstly it briefly charts the increase in air travel between Poland and the UK, considering the narratives of mobility cultures collected with the migrants. Secondly it investigates the collective dimension of travelling for migration on these flights and the tensions which emerge around this collectivity. Finally, it reflects on the wider costs and contexts of low cost shuttle flights as a late capitalist mode of migration transport.     

The impact of daily tour service quality on tourist satisfaction and behavioural intentions in an island context: a study on tours to Isla de la Plata,Ecuador

ABSTRACT

This study assesses the impact of daily tour service quality on tourist satisfaction and behavioural intentions in an island context. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the analysis of data collected from 195 participating in a daily tour to Isla de la Plata (Ecuador) showed that all the services examined (transportation by boat, food and beverage, tourist guide and visits) had a significant direct impact on tour satisfaction, having the transportation the highest impact. Moreover, the indirect effect of the daily tours services on behavioural intentions mediated by the satisfaction with the tour was also significant.     

Exploring the relationship between educational mismatch,earnings and job satisfaction in the tourism industry

This article analyses the interrelationship between educational mismatch, wages and job satisfaction in the Spanish tourism sector in the first years of the global economic crisis. It is shown that there is a much higher incidence of over-education among workers in the Spanish tourism sector than in the rest of the economy despite this sector recording lower educational levels. This study estimates two models to analyse the influence of the educational mismatch on wages and job satisfaction for workers in the tourism industry and for the Spanish economy as a whole. The first model shows that in the tourism sector, the wage penalty associated with over-education is approximately 10%. The second reveals that in the tourism sector the levels of satisfaction of over-educated workers are considerably lower than those corresponding to workers well assigned. With respect to the differences between tourism and the overall economy in both aspects, the wage penalty is substantially lower in the case of tourism industries and the effect of over-education on job satisfaction is very similar to that of the economy as a whole in a context where both wages and the private returns to education are considerably lower in the tourism sector.     

The effect of service quality and satisfaction on destination attractiveness of sub-Saharan African countries: the case of Ghana

This paper examines the functional forms of service quality (SQ) and satisfaction in relation to destination attractiveness. It focuses on the varying influence of destination characteristics, customer economics, and demographic variables to explore how SQ might be used to improve value positioning and, therefore, potential attractiveness of Ghana as a destination choice for tourists. Using methods triangulation data collection protocol, the paper finds causal links between SQ and selected composites of destination attractiveness (destination attributes, support services, facilities, and people-related factors) in the degree to which they influence customer satisfaction and return-visit intentions. The paper contributes refreshing insights useful for segmentation marketing, tour planning, and product/service development. The implications are far-reaching when considered alongside the fact that Ghana is relatively a new entrant into the organised tourism marketing arena and has the consequent imperative to scale-up structural and human capabilities to compete effectively with the more established global competitors.     

In-flight physical surroundings: quality,satisfaction, and traveller loyalty in the emerging low-cost flight market

The purpose of our research was to investigate the relationships among overall service quality, customer satisfaction, and behavioural intentions by considering the moderating impact of in-flight ambient conditions (air quality, temperature, odour, and noise) in the low-cost airline industry. A survey was conducted on international flights. Results of the structural equation modelling from a sample of 402 passengers indicated that quality and satisfaction are significant drivers of intentions; and satisfaction acted as a significant mediators. Additionally, supporting the moderating impact of ambience, findings from the tests for metric invariance revealed that the effect of satisfaction on intentions was stronger for the high air quality, temperature, odour, and noise groups than for the low groups; and the strength of the relationship between quality and intentions was greater in the high noise group than in the low noise group. Our results will help practitioners/researchers develop effective strategies/theories for passenger satisfaction and retention.     

Using accessibility measures to integrate land use and transport policy in Edinburgh and the Lothians

To ensure more effective integration of development and transport planning, new national planning policy guidance in the UK requires greater consideration of accessibility issues. Although quantitative accessibility analysis is common in research, the practical application of these techniques in land use planning has been rare, and assessment has been restricted to qualitative considerations. The strong policy focus on accessibility increases the need for robustness, but practical quantitative techniques are still evolving. This paper describes a structured approach to accessibility analysis, as part of the development of a new structure plan for Edinburgh and the Lothians, and demonstrates how an ‘integration index’ can be developed from accessibility measures to help compare alternative approaches.
