A new method for boarding passengers onto an airplane

We describe a new method to assign seats and to board passengers on an airplane that minimizes the total time to board. Steffen (2008) presents an optimum boarding method that assigns passengers to a specific numerical position in line that depends upon their ticketed seat location. Our method builds upon Steffen by assigning individual passengers to seats based on the amount of luggage they carry. Our heuristic method assigns passengers to seats so that their luggage is distributed evenly throughout the plane. Simulation results indicate that with our method, the total time to board all passengers on a fully loaded airplane is shorter than that of Steffen.     

Experimental test of airplane boarding methods

We report the results of an experimental comparison of airplane boarding methods. This test was conducted in a mock Boeing 757 fuselage, located on a Southern California soundstage, with 12 rows of six seats and a single aisle. Five methods were tested using 72 passengers of various ages. We found a significant reduction in the boarding times of optimized methods over traditional methods. These improved methods, if properly implemented, offer the potential for significant savings to airline companies.     

A study of the airline boarding problem

The airline industry is currently under intense pressure to simultaneously increase efficiency, customer satisfaction, and profitability. The boarding process is one way to achieve this objective as it lends itself to adaptive changes. The purpose of this paper is to determine the most cost-effective way to board passengers and still maintain quality and customer satisfaction. We conclude that the best strategy is to use a non-traditional methodology of outside-in or some modification thereof. The findings suggest that airline managers should consider issues related to evenly distributing boarding activity throughout the aircraft, developing more effective policies for managing carry-on luggage, and using simultaneous loading through two doors.

The National Cycle Strategy in the UK: to what extent have local authorities adopted its model strategy approach?

In 1996 the UK government announced a National Cycle Strategy (NCS) which included a model local cycle strategy. This paper reports on the findings of an ongoing research project, which seeks to evaluate the extent to which recently published local cycle strategies reflect best practice as enshrined in the model guidance. The results suggest that the level of take up of the model strategy is highly variable and ranges from authorities which adopt the model in its entirety to those that effectively ignore it. If government targets for increasing cycle use are to be achieved then it will be necessary for more local authorities to develop robust plans which are consistent with the NCS.
