An aggregate demand model for air passenger traffic in the hub-and-spoke network

Design of timetable for airport coach based on ‘time–space’ network and passenger’s trip chain

“…Therefore, the coach managers must pay attention to the connection of the dispatching times between the branch coaches and the trunk ones (Wei, Hansen 2006). Meantime, they must arrange the dispatching time of the trunk coaches according to the flight schedule.…”

What hurts the dominant airlines at hub airports?

“…Without intending to be exhaustive, this is a conclusion reported in Borenstein (1989), Brander and Zhang (1990), Brueckner et al (1992), 1 It is generally accepted that the route operations of airlines are subject to density economies (Brueckner and Spiller, 1994), and that airlines can attract more connecting passengers in a hub-and-spoke structure by increasing service frequency than by increasing aircraft size (Wei and Hansen, 2006). 2 Systematic data for the proportion of connecting passengers at Europe's large airports are not readily available.…”

A new approach to quantify the benefit to air travelers resulting from airport capacity expansion

“…Jorge and de Rus (2004) propose a theoretical framework to measure the benefits to passengers that result from the new airport projects, and propose a practical approach to estimate these benefits. Wei and Hansen (2006) classify the passengers' benefits resulting from airport capacity expansion into two categories: direct benefits and indirect benefits. Indirect benefits are obtained through airlines' adaptation and service improvements after expansion.…”

“…For the same number of passengers traveling through a hub airport, if airport capacity is increased, passengers will enjoy greater punctuality of flights and will experience less congestion. Wei and Hansen (2006) further develop a methodology to quantify the direct benefits in dollar values. They first build up an econometric passenger demand model for a hub-and-spoke network, and then quantify the passengers' benefits directly resulting from airport expansion by calculating the increase of consumer surplus after airport expansion based on the derived demand model.…”

“…They first build up an econometric passenger demand model for a hub-and-spoke network, and then quantify the passengers' benefits directly resulting from airport expansion by calculating the increase of consumer surplus after airport expansion based on the derived demand model. In this paper, we introduce a new approach to quantify the ''indirect benefit'' (term used in Wei and Hansen (2006)) to air travelers that results from airlines' adaptations in service frequency, aircraft size, and, etc. after airport capacity is increased.…”
