Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...

hazards in different areas have different effects and consequences. nowadays considering industries vital conditions, it seems necessary to boost organizations confronting uncertainties and risks. one solution for reducing these risks, is increasing agility, stability and flexibility in production process. this study tries to increase organization capabilities in supply chain hazards handing, u...

The proliferation of mobile computing has prompted navigation to be one of the most attractive and promising applications. Conventional designs of navigation systems mainly focus either indoor or outdoor navigation. However, people have a strong need for navigation from a large open indoor environment to an outdoor destination in real life. In this poster, we present a joint navigation system, ...

This paper focuses on an overview of an autonomous navigation system in maritime transportation that is supplied with intelligent guidance to avoid collision, while respecting the COLREGs rules and regulations and using expert knowledge in navigation for close quarter’s manoeuvres. The proposed collision avoidance process consists of two modules: a fuzzy logic based parallel decision making mod...

Recent studies in system resilience have proposed metrics to understand the ability of systems to recover from a disruptive event, often offering a qualitative treatment of resilience. This work provides a quantitative treatment of resilience and focuses specifically on measuring resilience in infrastructure networks. Inherent cost metrics are introduced: loss of service cost and total network ...

Multi-dimensional data (i.e., data referenced in one, two, three, and four dimensions) are often managed by transportation agencies with databases and technologies that cannot be integrated due in part to the lack of a comprehensive model for location referencing of the data. This lack of a comprehensive location referencing system data model limits organizations in implementing improved soluti...

Relevance feedback (RF) is an interactive process which refines the retrievals by utilizing user’s feedback history. Most researchers strive to develop new RF techniques and ignore the advantages of existing ones. In this paper, we propose an image relevance reinforcement learning (IRRL) model for integrating existing RF techniques. Various integration schemes are presented and a long-term shar...

In a peer-to-peer shared ride system, transportation clients with traffic demand negotiate with transportation hosts offering shared ride services for ad-hoc ride sharing in a continuously changing environment, using wireless geosensor networks. Due to the distinctive characteristic of this system—a complex and nondeterministic transportation network, and a local peer-to-peer communication stra...

one main group of a transportation network is a discrete hub covering problem that seeks to minimize the total transportation cost. this paper presents a multi-product and multi-mode hub covering model, in which the transportation time depends on travelling mode between each pair of hubs. indeed, the nature of products is considered different and hub capacity constraint is also applied. due to ...
