Investigating structural relationships between service quality,perceived value,satisfaction, and behavioral intentions for air passengers: Evidence from Taiwan

This study aims to investigate the relationships between service quality, perceived value, satisfaction, and behavioral intentions for air passengers through a structural equation model (SEM). The main study’s results are as follows. Service expectation has a significantly positive effect on perceived performance, but not on perceived value and satisfaction. Perceived performance has a significantly positive effect on perceived value, but not on satisfaction. Perceived value has a significantly positive effect on satisfaction. Both perceived value and satisfaction have significantly positive effects on behavioral intentions. In addition, perceived performance reveals the indirect effect on satisfaction moderated by perceived value. Finally, perceived value reveals a larger effect than overall satisfaction on behavioral intentions. Specific theoretical and managerial implications are discussed.     

Efficiency of the public and private bus transport sectors in Sri Lanka

The public and private bus sectors are in direct competition in most bus routes in Sri Lanka. Consequently, Sri Lanka is an ideal location to study their relative efficiencies. Five dimensions of transit performance are analyzed for comparing the relative efficiencies of the two sectors: cost efficiency, labour efficiency, input efficiency, revenue generation and safety. Productivity ratios are utilized for measuring the dimensions of transit performance. The productivity ratios for cost efficiency, labour efficiency in terms of total staff, input efficiency, revenue generation and safety in terms of accidents per bus showed the private bus transport sector to be more efficient than the public bus transport sector.     

Managing passenger behavioral intention: an integrated framework for service quality,satisfaction, perceived value,and switching barriers

This paper seeks to improve our understanding of passengers’ behavioral intention by proposing an integrated framework from the attitudinal perspective. According to the literature in marketing research, we establish a causal relationship model that considers “service quality-satisfaction-behavioral intentions” paradigm, perceived value theory, and switching barrier theory. Exploring passengers’ behavioral intention from satisfaction and perceived value help to understand how passengers are attracted by the company, while switching barriers assist in realizing how passengers are “locked” into a relationship with the current company. Furthermore, in order to capture the nature of service quality, we adopt a hierarchical factor structure which serves service quality as the higher-order factor. In this study, coach industry is selected as our research subject. The empirical results, as hypothesized, show that all causal relationships are statistically significant, and perceived value us the most important predictor of satisfaction and passengers’ behavioral intention. In conclusion, the managerial implications and suggestions for future research are discussed.

Learning from Los Angeles: transport,urban form,and air quality

Los Angeles is well known around the world as an automobile-oriented low density community, yet recent transportation policies have emphasized greater capital investment in rail transportation than in highways, and recent policies have attempted to discourage automobile usage through transportation demand management. While these policies have accomplished small shifts toward public transport and somewhat lower dependence upon singly occupied automobilies for work commuting, the financial costs of these policy changes has been very large in relation to their benefits. Proper pricing of transportation alternatives, more creative use of new and emerging transportation technologies, and the provision of many more opportunities for simpler private sector transport services, would all appear to be more promising as cost-effective approaches to coping with congestion in Los Angeles than the current regional transportation policies.     

Persuasive communication aimed at public transportation-oriented residential choice and the promotion of public transport

In this study, we developed a persuasive communication program to induce public-transport-oriented residential (PTOR) choice. We implemented an experiment that targeted students from the University of Tsukuba, Japan, who were in the process of changing their residential location. These students were randomly assigned to four groups: the first group was a control group; the second group received an information brochure about apartment flats typically used by students in Tsukuba city; the third group received a brochure identical to the one given to the second group, except that it also included information about the level of bus service for every flat; and the fourth group was provided with a leaflet that provided motivation for PTOR choice, in addition to the brochure used for the third group. The residential locations were investigated 5 months after the intervention. There was a significant difference between the control group and the third and fourth groups. The ratio of PTOR choice in the group with the information was twice as high as that for the control group. Furthermore, the persuasive message also increased PTOR choice. Additionally, the target groups’ frequency of bus use from home or the university was significantly high compared with the control group.     

Freight transport demand revisited: A microeconomic view of multimodal, multicharacteristic service uncertainty and the demand for freight transport

This paper provides a unifying framework for micro-based models of freight transport demand. An expected utility of profits model is posed that clarifies the conditions under which a system of equations (continuous) regression model should be used as opposed to the conditions that make a quantal choice model appropriate. The model also indicates the nature of subjective data that is necessary for estimating demand. In general, the conditions that give rise to the appropriate use of a quantal choice model imply that the needed subjective information is completely contained in the subjective probability distributions on the service characteristics; the utility function itself is irrelevant.

A survey of the Swiss public transport system and policy

This paper surveys Swiss public transport structure and policy. The regulatory regime is explained with the division between the two operators working under federal monopoly — the State railways (SBB) and the postbuses (PTT) — and the rest of the system. The rather complicated Swiss subsidy arrangements are described. The federal government's emphasis on introducing cheap public transport fares on environmental grounds through the federal transport measures (BTM) and the use of cheap fares in urban areas are discussed. The paper notes the Swiss people's rejection by a referendum of a federal commission's proposal for an integrated transport policy, though some of the solutions were introduced in their own right: the division of SBB into two parts, and the creation of the concept Rail 2000, later developed into Rail + Bus 2000. Finally, the paper reviews problems of the Swiss policy, including the future of cheap fares, making some comparisons with developments in Scandinavia.     

A comparison of the sustainability of public and private transportation systems: Study of the Greater Toronto Area

A macroscopic assessment of the impacts of private and public transportation systems on the sustainability of the Greater Toronto Area (GTA) is undertaken from economic, environmental and social perspectives. The methodology draws upon the urban metabolism and sustainability indicators approaches to assessing urban sustainability, but compares modes in terms of passenger-kms. In assessing the economic sustainability of a city, transportation should be recognized as a product, a driver and a cost. In 1993, the traded costs of automobile use in the GTA were approximately balanced by the value of the automobile parts and assembly industry. But local transit costs 1/3 to 1/6 of the auto costs per person-km, in traded dollars, mainly because local labour is the primary cost.Public transportation is more sustainable from an environmental perspective. Automobile emissions are a major contributor to air pollution, which is a serious contemporary environmental health problem in Toronto. Public transportation modes are less energy intensive (including indirect energy consumption) and produce CO₂ at an order of magnitude lower, although these benefits are partially undermined by under-utilization of transit capacity and the source of electricity generation.The social benefits of automobile use are likely more significant than costs in determining GTA residents' preferential mode choice. The speed and access of auto use provide important economic benefits, e.g. relating to employment and product choice. Nevertheless, offsetting the service attributes of private transportation are large social costs in terms of accidents. The costs of automobile insurance provide one tangible measure of such negative impacts.In order to improve the sustainability of the GTA, innovative approaches are required for improving the performance level of public transportation or substantially reducing the need for the service level provided by automobiles. Efforts such as greater integration of bicycles with public transit, or construction of light-rail systems in wide roadways, might be considered. But to be sustainable overall, a transportation system has to be flexible and adaptable and so must combine a mixture of modes.     

International private and public reinforcing dependencies for the innovation of automotive emission control systems in Japan and USA

In the beginning of the 1970s, the economies of USA and Japan were growing fast and environmental pollution was increasing to alarming levels. As passenger car emissions were found to be significant and rapidly increasing, their reduction was specially targeted. Following a bill passed by US Congress in 1968, requirements were set in 1970 for the vehicle manufacturers to reduce the emissions of carbon monoxide (CO) and hydrocarbons (HC) with 90% by 1975, and nitrogen oxides (NO_x) with 90% by 1976. These requirements were soon adapted to the Japanese regulatory framework, and were known in both countries as the “Muskie Act” or “Muskie Law” after the senator who developed the original bill.The new requirements spurred tremendous research and development efforts. Car manufacturers and research institutions in USA, Japan and Europe investigated and developed alternative solutions, including gas turbine and steam engine vehicles. California, the USA state with the most severe air quality problems and the only state at the time allowed to establish more strict requirements than federal regulation, established requirements implying the use of oxidation catalysts in 1975 and three-way catalysts (TWC’s) in 1977. Japan as a nation adopted similar requirements 1976 and 1978. Export of cars from Japan to USA increased rapidly. The rest of USA adopted emission standards similar to California’s only in 1981, timing USA vehicle sales rebound after the energy crisis and grave economic downturn. Strict requirements were thus established only after more than a decade of civic and legal processes between federal authorities, the car manufacturers and NGO’s.The history of vehicle development is one of cooperation and competition. This paper argues that the international cooperation on different levels of society (government, industry and science) together with commercial competition between the two countries was strong, continuous and instrumental in enabling the development of technology, appropriate regulation and infrastructural changes and thus created a market for cleaner cars and effectively reduced emissions from the growing vehicle fleet. In other words, the introduction of TWCs was reinforced by the simultaneous development of mitigating technology in two car producing countries competing for market space.     

Alternative information technologies for the provision of spatial information to public transport passengers in France,Germany and Spain

In France, Germany and Spain, the availability of computer‐generated itineraries to travellers in the street is still very limited, though growing slowly. Although many French towns have an effective passenger information system via Minitel, which will calculate itineraries, this is available only from the home. The vast majority of decisions about routes for journeys by urban public transport are still made using the traditional forms of spatial information abundantly displayed at bus stops and in vehicles: usually a map of the network and diagrammatic maps of individual bus or underground lines. Unfortunately a map of the whole network is often too complicated to yield the desired information easily. Alternatively the traveller may have the difficult task of comparing several diagrammatic maps of the individual lines departing from that bus stop, none of which alone can answer his spatial query: which bus lines, if any, go to my destination? The priority for the application of the computer should be the use of a geographic information system to generate automatically two types of less‐complicated map. The ‘stop‐specific route map’ shows on one piece of paper the routes of all buses from that stop, excluding of course the portions before the stop. The ‘zone map’ shows only the bus lines which serve a specific limited zone of the city, including at a reduced scale the portions extending out to their various destinations beyond the limits of the zone itself.

Urban passenger transport in the United States and Europe: a comparative analysis of public policies

This is the second part of a two‐part series that examines recent developments in urban passenger transport in the United States and Europe, focusing on the roles and impacts of the public sector as these have varied by country and over time. The first part of the series described public policies for roadway systems and private car use, whereas this second part concentrates on public transport. After a review of demand and supply trends, the article evaluates government policies in terms of public vs private ownership and operation, public regulation, financing responsibility by government level, types and amounts of subsidy, and impacts of ownership, regulation, and financing arrangements on costs and productivity. This second part concludes with an overall comparison between Europe and the United States, and considers how Europeans and Americans might learn from each other's successes and mistakes in order to improve transport policies.     

Impacts of motor vehicle operation on water quality in the US – Cleanup costs and policies

This paper investigates the costs of controlling some of the environmental impacts of motor vehicle transportation on groundwater and on surface waters. We estimate that annualized costs of cleaning-up leaking underground storage tanks range from $0.8 billion to $2.1 billion per year over 10 years. Annualized costs of controlling highway runoff from principal arterials in the US are much larger: they range from $2.9 billion to $15.6 billion per year over 20 years (1.6–8.3% of annualized highway transportation expenditures). Some causes of non-point source pollution were unintentionally created by regulations or could be addressed by simple design changes of motor vehicles. A review of applicable measures suggests that effective policies should combine economic incentives, information campaigns, and enforcement, coupled with preventive environmental measures. In general, preventing water pollution from motor vehicles would be much cheaper than cleaning it up.
