GetThere is a real-time passenger information system (RTPI) for rural areas that uses a citizen sensing approach to acquire information from public transport users. This paper describes the use of ontologies in GetThere to represent and integrate citizen sensors with data required to provide RTPI (e.g. timetable and route descriptions). The service architecture used to manage semantic sensor da...

Passengers experience significant inconvenience from track closures required for planned maintenance and infrastructure updates of rail networks. Generally, operators restore connectivity with shuttle busses replacing the closed link in the network. This however introduces additional transfers, while the speed of travel on busses for the replaced links is generally lower than the speed of the p...

Many of the existing methods for evaluating an airline’s on-time performance are based on flight-centric measures of flight delay. However, recent research has demonstrated that as much as 50% of passenger delays are caused by passenger travel disruptions, either flight cancelations or missed connections. The propensity for disruptions varies significantly across airports and carriers, based on...

Travel by bus with long hours will create discomfort feeling for bus passenger. Long hour travel will create physiological stress and psychological stress on bus passenger. It may due to vibration, noise, as well as seat comfort. Seat comfort is a subjective feeling of bus passenger. In this research, air cushion was used to replace the part of the seat foam. During the development of the integ...

Smart card data is increasingly used to investigate passenger behavior and the demand characteristics of public transport. The destination estimation of public transport is one of the major concerns for the implementation of smart card data. In recent years, numerous studies concerning destination estimation have been carried out—most automatic fare collection (AFC) systems only record boarding...

PROBLEM Child restraints (CRs) are vital for optimizing child passenger safety and reducing the risk of pediatric injury and fatality in motor vehicle crashes. However, most CRs are installed improperly. METHODS This present study was an assessment of observed instances of CR misuse. Participants were recruited through advertisements for CR inspection events in Los Angeles County, California....

IT components with information processing and communication capabilities are embedded in almost all commonplace and industrial objects. In our daily life we depend more and more on these IT components. On the other hand, users will increasingly expect that those IT components collaborate autonomously and thus provide emergent properties. Hence we have to guarantee their reliability, even though...

The purpose of the Air Transportation System (ATS) is to provide safe and efficient transportation of passengers and cargo. The on-time performance of the ATS is measured by flight-based metrics such as flight delays and flight cancellations. Researchers have shown that flight-based metrics do not accurately reflect the passenger trip experience, and especially underestimate the impacts of canc...

Informed driving is becoming a key feature to increase the sustainability of taxi companies. The sensors installed in each vehicle are providing new opportunities to automatically discover knowledge, which in return deliver information for realtime decision making. Intelligent transportation systems for taxi dispatching and time-saving route finding are already exploring this sensing data. In t...
