In intelligent transportation systems (ITS), transportation infrastructure is complimented with information and communication technologies with the objectives of attaining improved passenger safety, reduced transportation time and fuel consumption and vehicle wear and tear. With the advent of modern communication and computational devices and inexpensive sensors it is possible to collect and pr...

INTRODUCTION Air transportation systems are based on a variety of vehicles including fixed wing aircraft and helicopters. The most diverse and developed category remains the fixed wing aircraft with sizes ranging from single seat to 555 seats in the case of the Airbus A380. This size characterization relates to passenger vehicles. However, cargo aircraft have similar range of sizes. The largest...

Passenger behavior is the fundamental factor driving air transportation market reactions to the managerial decisions of airlines; therefore, it is important to understand passenger path choice process, and to develop a valid model to represent it. In this thesis, passenger disutilities are used to indicate passengers' sensitivity to alternative path options. Accordingly, passenger disutilities ...

In the process of the optimum design of aprons, solutions should be found for problems and such issues as the optimum area and dimensions of the apron, including the passenger and the cargo the number and dimensions of the gates on the basis of different types of aircraft parking configuration aircraft simulation and arrangement in different time periods of the given day at the airport. In this...

Intelligent transportation systems (ITS) have become common in public transit systems, particularly providing real-time transit information. For new implementations, it remains difficult to predict and quantify system and user benefits of technology implementation. Although previous studies have quantified the operational benefits of real-time transit traveler information systems, a gap in know...

The increased human mobility, combined with high use of private cars, increases the load on the environment and raises issues about the quality of life. The use of private cars lends to high levels of air pollution in cities, parking problems, noise pollution, congestion, and the resulting low transfer velocity (and, thus, inefficiency in the use of public resources). Public transportation serv...

BACKGROUND Little is known about train suicide and factors influencing its prevalence. This study tests the hypotheses that railway density, railway transportation volume, familiarity with railway transportation and population density contribute to train suicide. It also tests the relationship between train suicide and general population suicide and examines the prevalence and the characteristi...

Transportation networks constitute a critical infrastructure enabling the transfers of passengers and goods, with a significant impact on the economy at different scales. Transportation modes, whether air, road or rail, are coupled and interdependent. The frequent occurrence of perturbations on one or several modes disrupts passengers’ entire journeys, directly and through ripple effects. The p...
