Optimal paths computed by conventional path-planning algorithms are usually not “optimal” since realistic traffic information and local road network characteristics are not considered. We present a new experiential approach that computes optimal paths based on the experience of taxi drivers by mining a huge number of floating car trajectories. The approach(More)
A reliable and accurate short-term traffic forecasting system is crucial for the successful deployment of any Intelligent Transportation System. To address the complexity of real-world traffic forecasting conditions, this paper presents a layered traffic forecasting algorithm, which is implemented by a clustering neural network, Kohonen Self-Organizing Map(More)
This paper introduces a design framework for developing GIService web portals which are supported by Grid computing and Service-Oriented Architecture. A GIS web portal can be enhanced by Grid computing technologies to improve its performance, usability and security. The loosely-coupled Internet GIServices can be combined and integrated by implementing(More)
This article discusses how Participatory GIS (PGIS) can be improved by applying current start-of-the-art computing technologies, in particular high performance computing technology. The discussion covers the methods and tools for the four types of space-time collaboration situations (different place/time). While the four types are all addressed, the focus(More)
Current map generalization for massive spatial data is becoming more and more urgent. It is necessary to study the integration of new technologies, such as distributed computing, which is important to provide high-quality geographic information services. This paper proposes an architecture of automated map generalization in istributed environments, and(More)
Although Geographic information Systems (GISystems) have been widely used in both public and private sectors, geographic information is still not effectively used by common citizens for their everyday's life. A metropolitan spatial service infrastructure (MSSI) is a new vision to build a societal GIS allowing every citizen to create, share, and use(More)
