This study reports on a method to accomplish sensor validation and fusion in Intelligent Transportation Systems (ITS). The method is based on probabilistic and fuzzy techniques that express a confidence in the sensor data and take into account environmental factors and the state of the system....

This research project is concerned with sensor validation and sensor fusion as part of a five module hierarchical architecture for supervisory control. The goal is to enhance reliability and safety of the Intelligent Vehicle Highway System (IVHS) by taking into consideration the uncertainty of...

Ubiquitous computing application developers have limited options for a practical activity and location sensing technology that is easy-to-deploy and cost-effective. In this dissertation, I have developed a class of activity monitoring systems called infrastructure mediated sensing (IMS), which...

This article proposes a theoretical and practical extension of the IoT, taking in all "things" that can be sensed by sensors, without requiring them to be fitted with a tag or a digital network interface. These physical entities, whatever they may be (legacy appliances, passive items, subsets of...

The theory of Dempster-Shafer is discussed with emphasis placed on its use grown from the field of multisensor data fusion and data association systems. The aims of this paper are to investigate: how the structure of multisensor integration systems influences over the accuracy of objects...

This study reports on a preliminary design of a health monitoring system for automated vehicles. A new detailed nonlinear vehicle simulation which extends the current simulation is documented and will be used as a future testbed for evaluating the performance of the health monitoring system. A...

This paper describes a fault tree analysis of an automated freeway and how conformity to safety criteria can be demonstrated by fault tree analysis. The system is initially explained, followed by a discussion of hazard analysis, fault tree, and an analysis of the results. Readers are advised to...

This paper describes a fault tree analysis of an automated freeway. The design is characterized by extreme emphasis on vehicle-borne intelligence, and by the presence of a multiplicity of automated lanes. The system is platooned. At the end of the paper there is a brief discussion of the...

This dissertation presents a hierarchical, hybrid point of view to the control of large-scale systems. The analysis is based on a new hybrid dynamical system formulation that allows for the modelling of large scale systems in a modular fashion. Three problems are addressed: controller design,...

This report presents an evaluation of the Phase II Smart Card Demonstration Project, the goal of which is to develop a transit fare payment system for commercialization that will improve transit efficiency and effectiveness. The major focus of the project is the testing of selected technologies...
