This demo paper describes a real-time passenger information system based on citizen sensing and linked data.

Introduction. This paper examines the goal-directed information activity of passenger information staff, working in the dynamic environment of rail network control. The explicit aim is to define a meaningful set of information system requirements. The report shows how dynamic situations may lead us to question a number of established theories of information science. Method. Passenger informatio...

Current transit data collection systems emphasize either passenger counting or vehicle location information. The prototype described in this paper represents the integration of automatic passenger counting with automatic vehicle location to allow the automatic collection of transit system performance. The system involves the incorporation of RF/ID tags into bus passes for the purpose of improvi...

Public transport information provision in rural areas is often fragmented and of poor quality at best and non-existent at worst. This can have a significant impact on the everyday life of the inhabitants of rural areas, particularly in terms of limiting their travel choices and thereby their opportunities to access goods, service and social networks. Inadequate information provision also poses ...

Query-oriented update summarization is an emerging summarization task very recently. It brings new challenges to the sentence ranking algorithms that require not only to locate the important and query-relevant information, but also to capture the new information when document collections evolve. In this paper, we propose a novel graph based sentence ranking algorithm, namely PNR, for update sum...

The primary objective of the National Airspace System (NAS) is the transportation of passengers and cargo. It is no surprise, therefore, that passenger trip time performance is positively correlated with passenger satisfaction, airfare elasticity, and airline profits. Regulatory consumer information available to airline passengers provides measures of trip performance using only flight data (an...

In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...

Public transportation becomes increasingly diverse because of innovation in transport modalities and a large number of service providers. For facilitating passengers’ comfort, intermodal passenger information systems are required, which combine data of different providers and transport modes. Therefore, context sensitive mobile applications are promising solutions to supporting passengers at ev...
