The energy consumption of animaland plant-based diets and, more broadly, the range of energetic planetary footprints spanned by reasonable dietary choices are compared. It is demonstrated that the greenhouse gas emissions of various diets vary by as much as the difference between owning an average sedan versus a sport-utility vehicle under typical driving conditions. The authors conclude with a...

The performance metric used to evaluate on-time performance in the US airline industry is flight-based, measuring the number of flight legs with arrival delay of 15 minutes or more. We analyze airline passenger operations and schedule performance and conclude that this flight-based performance metric does not accurately reflect delays to passengers, primarily because it does not recognize the l...

Low-carbon public passenger transport is an important part of low carbon city. The CO2 emissions of public passenger transport in Tianjin from 1995 to 2010 are estimated with IPCC CO2 counting method, which shows that the total CO2 emissions of Tianjin public passenger transport have gradually become stable at 1,425.1 thousand tons. And then the CO2 emissions of the buses, taxies, and rail tran...

Many of the existing methods for evaluating an airline’s on-time performance are based on flight-centric measures of flight delay. However, recent research has demonstrated that as much as 50% of passenger delays are caused by passenger travel disruptions, either flight cancelations or missed connections. The propensity for disruptions varies significantly across airports and carriers, based on...

? ho is remembered chiefly for the disasters of the Franco-German war and 0r his capture by the Germans at Sedan. Inevitably he has suffered by comj^rison with his famous uncle, the great Napoleon Bonaparte, and he has jj?1* dismissed as a weak and irresolute man of small capacity, and even sj!611 ^ubbed Napoleon the Little. To live in the shadow of genius is no easy Ration for any man, and Lou...

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...

The purpose of the Air Transportation System (ATS) is to provide safe and efficient transportation of passengers and cargo. The on-time performance of the ATS is measured by flight-based metrics such as flight delays and flight cancellations. Researchers have shown that flight-based metrics do not accurately reflect the passenger trip experience, and especially underestimate the impacts of canc...

A fundamental component of any National Airspace System (NAS) performance evaluation is the cost impact of air traffic delays, and more generally capacity limitations, on the travelling passengers. In previous research it has been conclusively shown that flight delay data and flightcentric metrics fail to accurately represent the passenger travel experience and passenger trip delays accurately....

As rail station patronage levels increase, so too does the load on the entire railway system. The higher passenger densities exacerbate local egress issues and thus adversely affect dwell time and subsequently punctuality, along with the passenger experience. Devices such as barriers are regularly used to influence passenger egress. However, their use is typically limited to special events; whe...
