Intelligent Transportation Systems (ITS) plays a significant role in the traffic management, i.e. traffic jam prediction, route guidance. Due to the hardware failure or data transformation failure, some traffic observation data may be occasionally missed, which seriously affect intelligent transportation information service. So, the completion of traffic observation data has now become an issue that...
It has been proved that the adoption of traffic sensing data can reduce traffic jam, and improve traffic volume. However, traffic sensing by both vehicles and road monitoring infrastructures faces the problem of data missing on dimensions of time and space, which makes data reconstruction a challenge for full-time and wide-area traffic sensing. Exploiting the hidden structure of the traffic data,...
Despite the fact that wireless sensor networks (WSNs) have been applied to structural health monitoring (SHM) systems of civil infrastructure, the reliable data transmission is very challenging for structures far away from data center due to long transmission distance. In this paper, we present a novel architecture that high-speed train takes the role of a mobile sink to assist the data collection...
On the basis of extant literature, we built a conceptual model of the relationship among Perceived Quality, Perceived Value, Satisfaction, Sense of Belonging and Usage, and proposed some hypotheses about the influencing factors of continued system usage in SNS. To test the hypotheses, we designed a questionnaire, and conducted a survey in Xidian University. We used SPSS13.0 to analyze the collected...
We propose a theoretical framework about the factors that affect knowledge sharing in governmental fiscal departments. The framework is about the relationship between information technology, trust, knowledge sharing intention and knowledge sharing behaviors. Seven hypotheses are proposed based on the framework. These hypotheses are confirmed through a field survey of 169 employees from 5 governmental...
