Safety is considered as some of the most important operational characteristics of contemporary civil aviation. An extensive regulatory structure has been established to supplement the private airline, airport and air navigation systems, incentives to limit the risks of flying. This paper reviews the research on risk and safety modelling in civil aviation. In such a context, the basic concepts and definitions of risk, safety and their evaluation are described. The review focuses on four categories of models for safety assessment: causal for aircraft and air traffic control/management operations, collision risk, human factor error and third-party risk. 相似文献

Despite the explosive growth of the Chinese aviation sector and the major industry reforms undertaken in recent decades, the Chinese domestic market remains highly concentrated with a significant element of regulation and governmental control in areas such as market entry and airline fleet planning. In this study, we investigate the frequency strategies and aircraft choices of airlines operating in this concentrated growth market. Our empirical investigation suggests that airlines mainly accommodate rapid traffic growth by flying more frequently, although increased aircraft size also contributes to market expansion. We also find a negative relationship between market concentration and flight frequency. Due to the more balanced market structure resulting from mergers among leading airlines since 2002, there has been a moderate reduction in market concentration at route level, contributing to a 3.7% increase in traffic volume from 2002 to 2008. The results of our study suggest that Chinese travelers have yet to fully enjoy the benefits of market liberalization, and airports should prioritize increasing capacity related to aircraft movements over the accommodation of larger aircraft. 相似文献

This article discusses how the slowdown in the real estate market during the most recent economic and financial crisis has affected residential tourism destinations on the Spanish coast. The afore-mentioned crisis, which gave rise to a standstill in residential activity, coincided with the turbulences experienced in the competing destinations of Northern Africa, which brought about a record number of international tourist arrivals to Spain. The resulting situation enables us to explore the future scenario of all the Spanish destinations that, due to the depletion of available land, are reaching their maximum levels of urban growth. Examining the case of Calpe, a destination which is representative of the Spanish Mediterranean, the study analyses whether the foreseeable dynamics for the future are conceptualized in the favourable terms that characterize “sustainable development” or, on the contrary, exhibit negative implications which the classic economists refer to as the “steady state”. 相似文献

Validating the international tourist role scale 总被引:1,自引:0,他引:1
This study was designed to validate the international tourist role scale and the three dimensions it revealed. The purpose of this attitudinal scale was to measure the tourist role typology. United States adult outbound tourists flying with 11 major airlines returned useful questionnaires. This study validated the role scale as a reliable one that properly identified three conceptual dimensions of international tourist typology and successfully provided measures of tourists’ novelty-seeking preferences on the three dimensions. The study demonstrated, however, that the scale would measure the novelty-seeking preferences of international tourists more effectively if it were supplemented by other measures. 相似文献
