The raison d’etre for the air transportation system is the movement of passengers and cargo. Consumer information for airline passengers and regulatory consumer protection of airline services provide measures of performance using the percentage of on-time flights, and the percentage of cancelled flights. Researchers have shown that these “flight-based” metrics are a poor proxy for measuring the...

Travel by bus with long hours will create discomfort feeling for bus passenger. Long hour travel will create physiological stress and psychological stress on bus passenger. It may due to vibration, noise, as well as seat comfort. Seat comfort is a subjective feeling of bus passenger. In this research, air cushion was used to replace the part of the seat foam. During the development of the integ...

This paper deals with how to develop a model to forecast air passenger demand and to evaluate some policy scenarios related with runway and passenger terminal capacity expansion to meet the future demand. System dynamics frameworks can be used to model, to analyze and to generate scenario to increase the system performance because of its capability of representing physical and information flows...

In this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. To achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. The length of gasper air flow was compared with the distance between gasper outlet and...

Air bags, when used as a supplement to safety belts, effectively prevent deaths and serious injuries in frontal motor-vehicle crashes. Air bags are standard equipment in most new cars; federal safety standards require that all new passenger cars and light trucks be equipped with both driver- and passenger-side air bags by 1999. The safety of air bags is well documented, and air bags have saved ...

We use data on air passenger travel expenditures per passenger as well as statistical analysis of the air traffic lost for the two-year aftermath of the September 11, 2001, attacks to estimate direct demand losses for air transportation services. These are used along with a national input-output model to assess the full costs of these losses. Depending on assumptions made, the full losses to th...

We examine the impact of post-9/11 airport security measures on air travel in the U.S. Using five years of data on passenger volume, we evaluate the effects of the implementation of baggage screening and the federalization of passenger screening on the demand for air travel. These two congressionally mandated measures are the most visible changes in airport security following the 9/11 attacks. ...

abstract efficiency concept has a long history in the sciences and its measurement and analysis is a vital importance for firms to achieve the best performance. hence, the aim of this paper is efficiency evaluation of mahan air compared to iata member airlines in middle east and africa. for this purpose, the indicators include available ton kilometer, revenue ton kilometer, revenue passenger ki...

With the rapid development of technology, the comfort of service has become an important issue. Air travels, especially long distance, may cause both physiological and psychological discomfort to passenger. Passenger comfort is clearly a main factor in user’s acceptance of transportation systems. Sleeping is one of the common activities during the long haul flight. In this paper, subjective and...
