The airlines provide a critical service to the nation’s economy, providing rapid, safe, and affordable transportation over large geographic distances. The reliability of this transportation service, defined as the difference between the ticketed arrival time and the actual passenger arrival time, translates into economic productivity. For example, in 2007, the total delays experienced by airlin...

Wearable and accompanied sensors and devices are increasingly being used for user activity recognition. However, typical GPS-based and accelerometer-based (ACC) methods face three main challenges: a low recognition accuracy; a coarse recognition capability, i.e., they cannot recognise both human posture (during travelling) and transportation mode simultaneously, and a relatively high computatio...

Carpooling is an appropriate solution to address traffic congestion and to reduce the ecological footprint of the car use. In this paper, we address an essential problem for providing dynamic carpooling: how to compute the shortest driver’s and passenger’s paths. Indeed, those two paths are synchronized in the sense that they have a common subpath between two points: the location where the pass...

Abstract-In this paper, correspondences are drawn between two game theory models (Nash noncooperative and Stackelberg games) and some problems in transportation systems modelling. An example of each is described in detail, namely the problem of carriers competing for intercity passenger travel and the signal optimization problem. The discussion serves to underline differences between two catego...

Numerous studies have illustrated how denser urban forms lead to smaller greenhouse gas (GHG) emissions from passenger transport. Many of these studies have excluded aviation since the association between urban structure and air travel is not as intuitive as it is the case of ground travel. However, several recent studies have concluded that air travel is a significant contributor to the GHGs f...

OBJECTIVES This study longitudinally examines the impact of transportation support on driving cessation among community-dwelling older adults residing in retirement communities. METHOD Data came from 3 waves of the Florida Retirement Study (1990-1992), a population-based cohort study. Analysis was limited to participants who drove at baseline and were reinterviewed in 1992 (N = 636). Transpor...

This work describes the development of a distributed agentbased application devoted to the flexible transportation of passengers. The system considers the planning and control of trip requests comming from clients. The underlying 3-tier agent architecture, named MADARP, provides a set of base agents organized around an interface, a planning and a service layer. Interface agents provide GUIs for...

Recently, Northeast Asia has become one of the three largest trade areas, covering approximately 30% of the total trade volume of the world. However, the distribution facilities are saturated due to the increase in the transportation volume within the area and with the European countries. In order to accommodate the increase of the transportation volume, the transportation networking with the m...

A station closure is an abnormal operational situation in which the entrances or exits of a rail transit station have to be closed for some time due to an unexpected incident. A novel approach is developed to estimate the impacts of the alternative station closure scenarios on both passenger behavioral choices at the individual level and passenger demand at the disaggregate level in a rail tran...
