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...

The ceaselessly increasing number of trips on urban highways and major arterial roads have caused serious congestion and air pollution problems. Thus many transportation agencies have persevered in their efforts not only to alleviate such problems, but also to minimize social costs. However, the complex nature of such problems has strongly hindered transportation agencies’ ability to consider a...

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...

This thesis investigates the potential uses of information technologies for transit applications; specifically to the real-time functions of operations monitoring and control and passenger information. To an agency that is currently considering technology to improve performance, this thesis guides the agency through the many issues that should be addressed. The research first investigated the i...

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...

It is difficult to determine whether specific weather events like the storms in Washington can be definitively attributed to climate change or if they are severe storm occurrences within otherwise natural weather patterns. However, consensus in the scientific community indicates that major storms and other events including inundation of coastal roads from a rising sea level, erosion of roadways...
